Most companies have no reliable way of knowing how corporate email accounts are being used, whether policies are being followed, or if critical data is being shared on unmonitored platforms. Malware does more than steal credentials. Infostealers’ bounty includes live sessions, saved credentials, browser configurations, and user interactions across infected devices throughout an organization. It reveals how employees behave, exposes how endpoints are configured, and highlights failing security policies. With such data in hand, bad actors can pinpoint an organization’s real-world weaknesses, beyond the perimeter monitored by logs or enforced by compliance checklists.  The good news is that organizations and defenders can use that same information to protect themselves and fight back.

In this third installment of the series, we explore policy violations, insecure practices, and endpoint weaknesses that silently expand the organizational attack surface. Drawing on findings from the Constella 2025 Identity Breach Report and given context by Kineviz’s visual analytics platform, we demonstrate how to use the intersection of behavioral and technical signals to expose systemic vulnerabilities before bad actors find them first.

Policy Violations: When Acceptable Use Becomes Unacceptable Risk

Acceptable Use Policies are designed to protect organizational assets by defining clear boundaries for how corporate accounts, devices, and identities should be used. But, the reality is that there is no such thing as a human firewall. Organizations can not enforce or monitor the intent or digital behavior of each employee in real time. The truth derived from infostealer data is that these boundaries are routinely ignored in day-to-day practice.

One frequently observed violation is the use of corporate email accounts to register on unauthorized platforms, whether they are social media sites, browser plugins, streaming services, or online marketplaces. In some cases, employees may be using their corporate email addresses on adult content platforms or online gambling services. Often times, these registrations are made from personal or unmanaged devices, which then become targets for malware infections. Once attackers exfiltrate credentials and session tokens, they gain access to potentially sensitive corporate resources as well as to those external services.

Whether intentional or accidental, these violations increase legal and operational risk. More importantly, they erode the boundary between internal systems and external exposure, creating opportunities for lateral compromise that security teams often cannot see until it is too late.

Password Reuse: Bridging External Infections with Internal Impact

Constella’s analysis shows that password reuse between personal and professional accounts remains one of the most common enablers of compromise. Employees frequently reuse passwords across unrelated services, often with minor variations, or use the same login combination for both internal systems and consumer applications. While this may be more convenient for the user, it opens the door to the organization if the password is compromised by a bad actor.

Organizations have no direct way to measure this behavior. Endpoint agents and IAM systems cannot detect whether a user is reusing the same password on a third-party site, nor can they prevent it unless password managers or strict vaulting practices are universally adopted and enforced. Even then, as mentioned, people find ways around them. This lack of visibility means that an employee’s compromised gaming account, shopping profile, or personal email account can silently open the door to a breach.

However, just as bad actors use the data they glean to pinpoint weaknesses for exploitation, organizations can use infostealer data to identify where and how they need to shore up their defenses. By analyzing infections at scale, companies can detect high-risk usage patterns that were invisible before.

Security teams who use Kineviz’ GraphXR can visualize data relationships, trace risk back to its origin, identify affected users and systems, and define clear priorities for containment and training.

By analyzing aggregated infections, security teams clearly see password reuse across domains and platforms. Infection analysis regularly finds credentials tied to cloud admin consoles, CI/CD tools, or customer databases side by side with consumer services or non-sanctioned applications.

Endpoint Exposure: A Reflection of Real-World Vulnerabilities

Infostealers not only extract credentials, they also capture detailed metadata about the infected environment. This includes browser versions, system configurations, running processes, antivirus products, and even clipboard contents or autofill settings. This technical context provides direct insight into which devices are most vulnerable and how malware is evading detection.

Among the findings surfaced in the 2025 report:

• Chrome, Firefox, and Edge are the most frequently targeted browsers due to their market share and extensive storage of session cookies and credentials.
• Antivirus evasion is widespread. Infostealer logs show infections on systems that report running up-to-date antivirus tools, suggesting misconfiguration, outdated signatures, or user-level bypasses.
• Infection hotspots vary significantly by geography, often correlating with weaker IT maturity or less frequent device patching and monitoring. These regions frequently include outsourced operations, contractors, or satellite offices where central control is limited.

Kineviz allows organizations to visualize these infections across office locations, endpoint types, and operating systems, enabling risk segmentation that aligns with actual exposure rather than policy assumptions.

From Static Policy to Adaptive Defense

The convergence of behavior and endpoint visibility allows organizations to shift from static security policies to contextual defense strategies. Diving into the data, gives teams the power to figure out where security policies are failing so they can focus their remediation efforts where the risk is highest.

Recommendations include:

1. Correlate identity data with device intelligence
   Combine credential exposure with endpoint metadata to understand infection conditions, identify vulnerable builds, and prioritize device-level hardening.
2. Visualize violations and usage drift
   Use graph-based analysis tools like GraphXR to group corporate identities misused on unapproved services or linked to high-risk behavioral patterns.
3. Deploy role-based awareness campaigns
   Train users on behavior as much as job function. For example, employees using the same password across services should receive targeted training and forced credential resets.
4. Monitor high-risk geographies and external partners
   Track infections across contractors, offshore teams, and unmanaged endpoints to detect weak links in distributed environments.
5. Implement policy validation with real data
   Replace static policy enforcement with continuous validation, driven by intelligence from real-world infections and endpoint activity.

Final Thoughts

Infostealers don’t just exfiltrate data. They dynamically sense policy violations, behavioral risks, and endpoint misconfigurations and can provide real benefits to the bad actors or to the organization attacked. If the information stays buried in disconnected logs, those benefits remain latent. However, if transformed into intelligence, then they can power adaptive, visual, and context-rich defense.

The absence of visibility into real employee behavior—how identities are used, where they appear, and which systems they access—creates blind spots that attackers actively exploit. No firewall can stop a user from making a poor security decision. But with deep infostealer intelligence from Constella and advanced visual analytics from Kineviz, organizations can finally see the risk for what it is, map it across users and endpoints, and act before it escalates.

As infostealer malware continues to scale in reach, automation, and precision, organizations face an increasingly urgent challenge: a lack of comprehensive visibility across their identity exposure landscape. While credential leaks and cookie thefts are often detected in isolation, without centralized and time-aware analytics, security teams cannot understand the true extent and persistence of the threat.

This article outlines the critical elements required to close this visibility gap. Using data provided by Constella’s Identity Breach Report and delivered through Kineviz’s graph-powered analytics platform, we explore how organizations can use exposure segmentation, behavioral analysis, and temporal monitoring to turn infostealer intelligence into protective action.

Visualizing Strategic Exposure: From Fragmented Incidents to Global Awareness

Identity issues frame a variety of threats. They are critical when attempting to assess which geographies are under attack, whether certain countries are more targeted by threat actors, or whether there are internal deficiencies, such as low levels of security awareness or weaker hygiene practices that lead to password or credential sharing.

The larger the organization, the greater the hazard. Why? Because identity (however defined) is the key to access every subgroup, unit, division, and device. Without a consolidated view that links infections, credentials, and threat activity across countries and business units, security and risk leaders are forced to work with fragmented signals.

The challenge is to put all of this disparate information into a context that makes it possible to choose a plan of action. In a visual environment that explicitly shows connection between data, such as Kineviz’ GraphXR, organizations can, for example, transform raw infostealer logs into dynamic, interactive intelligence maps.

Such maps allow decision-makers to explore the identity threat surface across regions, teams, and technologies, making it possible to identify hotspots.

More specifically, using the information to track password patterns across regions, an organization might discover that offices in a specific country consistently use weak or reused credentials. Or, perhaps that local employees are registering corporate email addresses on high-risk consumer platforms. Such maps could reveal that regional exposure aligns with known adversary operations or geopolitical targeting patterns.

Such operational intelligence cannot be derived from isolated alerts or static dashboards. It requires the ability to explore and interact with relational data at scale, enabling organizations to go beyond detection towards true understanding.

Temporal Trends: Seeing Exposure Over Time

Timeline-based monitoring is another key element in closing the visibility gap. Security teams need to know:

• Is our phishing training actually reducing infections?
• Did the endpoint protection upgrade in Q2 reduce exposure?
• Are infections spiking after software rollouts or travel seasons?

Tracking infostealer telemetry across time reveals trends otherwise buried in static lists. By visualizing when credentials are exfiltrated, reused, or republished on dark web markets, organizations can assess whether their controls are working—or whether attackers are simply shifting vectors.

Kineviz’ GraphXR helps analysts slice infostealer intelligence by time, helping them detect waves of infections, correlate attacks with specific events (e.g., policy changes, layoffs, partner integrations), and measure the impact of remediation efforts.

Behavioral Weaknesses: The Hidden Patterns Behind Exposure

Besides geography and time, poor identity hygiene remains a critically underexplored root cause of infostealer impact. Constella’s analysis of 2024 data revealed multiple habitual behaviors driving exposure risk:

• Password reuse across personal and corporate services remains widespread.
  Infected users routinely store both business and consumer credentials in browser autofill.
• Shared credentials in production environments, particularly among DevOps and engineering teams, continue to appear across stealer logs, suggesting systemic violations of identity isolation policies.
• Weak passwords that clearly violate corporate policy appear not only in internal systems, but on third-party platforms where employees use work credentials for unapproved services.

These behaviors persist because they are difficult to detect in real time. However, the data forms clear patterns when infostealer logs are aggregated and visualized. Visual analytics reveal behavioral clusters, groups of employees using the same root passwords, storing credentials across unrelated services, or sharing privileged access. This behavioral context enables targeted interventions, not generic awareness campaigns. Now analysts can pivot from “this account was exposed” to “this role, region, or department has a recurring pattern of weak password usage.”

From Incident Response to Exposure Management

To close the visibility gap, organizations must elevate their infostealer response from tactical containment to strategic intelligence. This transformation depends on five key strategies:

• Centralize global telemetry
  Aggregate infostealer logs, credential leaks, and identity artifacts across all organizational domains, subsidiaries, and regions.
• Visualize exposure context
  Use platforms like Kineviz to connect identity elements, employee roles, geographic regions, and session data in real time, enabling meaningful exploration and segmentation.
• Track remediation over time
  Build timeline-based workflows that show how infection rates and exposure patterns evolve after security initiatives, training campaigns, or infrastructure changes.
• Detect patterns at the organizational level
  Move beyond individual detections to surface collective risk signals, such as password reuse clusters or role-based exposure profiles.
• Translate visibility into strategic policy
  Leverage this intelligence to inform acceptable use policies, endpoint configurations, access controls, and region-specific training efforts.

Final Thoughts

The volume of exposure is no longer the primary challenge. The real threat lies in the lack of insight. Without centralized, temporal, and behavioral visibility, organizations are forced to remain reactive, merely treating symptoms while systemic vulnerabilities persist beneath the surface.

By combining Constella’s deep infostealer intelligence with the advanced visual analytics provided by Kineviz’ GraphXR, organizations gain the ability to see their exposure, not just list it. This visibility enables faster response, more effective remediation, and ultimately, better decisions to promote enterprise security.

Infostealer malware dominates today’s cyber threat landscape. Designed to extract credentials, cookies, session tokens, autofill data, and other forms of digital identity, infostealers operate silently, persistently, and at industrial scale. They are no longer just a precursor to other attacks—infostealers are the breach.

There are two critical vectors of risk: employee-driven and user-driven infections. Yet many organizations treat these threats uniformly, without differentiating between them. Crucially, each introduces fundamentally different threat dynamics, requiring distinct detection strategies, containment protocols, and long-term mitigations.

This article, co-authored by Constella Intelligence and Kineviz, combines large-scale infostealer telemetry data with advanced visual analytics to demonstrate how organizations can understand and contextualize these evolving exposures. The foundation of this analysis is the Constella 2025 Identity Breach Report, which tracks over 219,000 breach events, 107 billion exposed records, and 30 million infected devices observed across deep and dark web sources. GraphXR, Kineviz’ graph data analytics and visualization platform, provided the means for the analysis and visualizations.

Employee Infections: A Gateway to Internal Compromise

Infostealers that target employees directly threaten enterprise systems. Why? Attackers exfiltrate credentials from devices used to access email, cloud services, production infrastructure, or collaboration platforms. With these credentials in hand, attackers win immediate access to the operational backbone of an organization. Constella’s data shows that infostealer logs included internal credentials in 78% of recently breached companies within an examined six-month window of compromise.

More than 30% of ransomware attacks in 2024 started with access acquired through infostealer infections. Attackers deployed infostealers like LummaC2, Redline, and Vidar to extract credentials which they either resold or reused. These infections also frequently evade detection on unmanaged or BYOD (bring your own) devices, especially in hybrid work environments.

Moreover, 95.29% of credentials exposed via infostealers in 2024 were found in plaintext, a dramatic increase from the previous year. The implications are clear: attackers don’t break in when they can simply log in.

User Infections: External, Yet Highly Impactful

While user-side infections may not directly affect enterprise systems, their impact is no less severe. What makes this type of exposure so dangerous is its latent pathway into internal systems. If an organization has federated authentication, shared credentials, or weak access controls in place, attackers may escalate privileges or move laterally using external identities. With 60% of 2024 breach datasets composed of recycled credentials, attackers often combine user- and employee-exposed data to uncover new attack paths.

Employees regularly use corporate devices to access personal accounts and vice versa. Constella’s telemetry has repeatedly shown cases where session cookies and credential pairs recovered from “user” infections include logins to administrative dashboards, internal cloud environments, or IT vendor platforms.

Attackers use credentials stolen from customers or partners to take over accounts (ATO), commit fraud, and abuse platforms. This increases the operational burden on support teams, drives up fraud losses, and even introduces brand-level risk when attackers use hijacked user sessions to phish or commit fraud.

The Critical Role of Visual Analytics in Deep Infostealer Intelligence

The dynamic nature of identity exposure—where a single infostealer infection may leak credentials across dozens of unrelated services—requires a different investigative model. Security teams must move away from static analysis of email domains or leaked passwords and begin treating infostealer datasets as high-context, interconnected threat maps.

The scale and relational complexity of Constella Intelligence’s infostealer data lakes demands a way to understand its significance beyond creating lists of actors and leaks. This is where Kineviz adds critical value. Through graph-powered visual analytics, teams can explore infostealer data in real time, connecting credentials, session artifacts, device metadata, and behavioral signals across internal and external entities. This gives analyst teams the insight they need to address the security issues as an interconnected ecosystem and to create plans to mitigate them.

Kineviz’ GraphXR enables security teams to visually distinguish and separate employee infections from user-based exposures, mapping each population independently while also exploring their intersections. This structured separation is fundamental when trying to tailor containment strategies or when reporting risk by department, geography, vendor, or user segment.

Furthermore, the ability to operate at scale across millions of credentials allows analysts to extract collective intelligence from affected populations. Instead of responding to threats one by one, teams can investigate clusters—such as all developers using a compromised plugin, or all employees sharing credentials with leaked user accounts. These insights help uncover shared infrastructure, behavioral patterns, or systemic security weaknesses that wouldn’t emerge from individual case analysis.

Kineviz’s visual engine also allows threat intelligence teams to:

• Group infostealer logs by attack vector or malware family (e.g., Redline vs. Lumma)
• Identify concentrations of exposure by business unit, role, or application
• Tag and monitor known vendors, executives, or contractors as high-risk nodes
• Segment remediation by use case: phishing risk, lateral movement, ATO, privileged access, etc.

The result is a shift from flat reporting to visual, contextual threat modeling, where security teams can rapidly see, segment, and prioritize threats by relevance and business impact. Visualization is no longer a reporting feature—it is an investigative tool and a decision accelerator.

Recommendations

1. Adopt a Dual-Lens Threat Model
   Separate internal and external exposures in your detection stack—but correlate them where identity overlap is suspected.
2. Leverage Visual Graph Analysis
   Use tools like those developed by Kineviz to visually explore infostealer logs and extract macro-level patterns across users, malware types, and threat actors.
3. Operationalize Infostealer Intelligence at Scale
   Treat infostealer data as the backbone of identity threat modeling. Avoid treating incidents in isolation—group them to detect systemic exposures.
4. Track Beyond Credentials
   Monitor for session tokens, authentication cookies, and configuration artifacts. These are increasingly used to bypass MFA and impersonate users.
5. Expand Awareness Across the Organization
   Train employees, fraud teams, and risk stakeholders to understand how infostealer risk impacts them—even outside the traditional security perimeter.

Final Considerations

Infostealers are not a niche threat. They are the operational mechanism behind today’s largest-scale identity attacks. According to the Constella 2025 Identity Breach Report, nearly every major breach now involves infostealer data, reused credentials, or session artifacts obtained via these infections.

Responding effectively requires more than threat feeds, it requires context, correlation, and visibility. Through the joint power of deep infostealer intelligence from Constella and real-time visual exploration from Kineviz, organizations gain the clarity needed to defend at the speed and complexity of modern threats.

At Constella, we’ve spent years analyzing how cybercriminals execute attacks that affect organizations of all sizes, whether they’re startups, local businesses, or global enterprises. One of the most revealing recent cases involves the abuse of Email Marketing Platforms like MailChimp, whose accounts are being compromised through account takeover (ATO), phishing, and social engineering tactics. These attacks are not only persistent, they’re scaling globally and affecting multiple sectors with serious consequences.

What Makes Email Marketing Platform, MailChimp, an Ideal Target?

MailChimp has long been a critical communication tool for marketing teams, tech newsletters, and even cybersecurity organizations. Access to a MailChimp account typically gives attackers:

• Full lists of subscribers and contact information
• The ability to send mass emails from a trusted source
• The potential to impersonate trusted brands and individuals
• Intelligence on marketing or internal communication strategies

Even with multi-factor authentication (MFA), many of these accounts are being accessed by bypassing traditional login processes.

How? Through the use of stolen session cookies. Infostealers, malware families designed to extract stored credentials, browser cookies, and app data, are a common threat vector. Once cookies are exfiltrated, attackers can bypass login flows entirely, rendering MFA useless.

Thousands of new fresh infections in the last few days

In just the last few days, Constella has detected +1.2K newly infected devices that contained MailChimp credentials. These are not historical records, they are fresh net new infections, actively putting sensitive accounts at risk.

What’s more, this data highlights a worrying trend: attackers are increasingly targeting corporate environments, not just personal users. Many of the domains associated with these infections belong to legitimate businesses across multiple sectors and geographies.

Global Spread: Countries Most Affected

A recent analysis of infections paints a clear picture of the global nature of this threat. The following countries are seeing the highest rates of MailChimp-related compromises in the past month:

• Mexico (13.46%)
• Australia (8.65%)
• Colombia (8.65%)
• Brazil (5.77%)
• France (5.77%)
• India (4.81%)

These infections are not just hitting random individuals; they’re breaching the digital walls of corporations, nonprofits, and educational institutions alike.

Targeted Sectors: Who’s Being Hit?

By filtering recent infostealers logs, we’ve identified that the following sectors are among the most impacted by this type of threat:

The sectors most affected include:

Education

Educational institutions continue to be attractive targets due to legacy systems and limited cybersecurity resources. These platforms often support large-scale virtual learning environments, making them vulnerable to entry points.

Marketing & Digital Media

Companies offering marketing and digital solutions are high-value targets due to the client data they process. These organizations often operate in highly connected ecosystems, making lateral movement easier for attackers once inside.

Technology & IT Services

Tech companies, including software developers and IT solution providers, also featured heavily. This sector represents both a high-risk and high-reward category for threat actors due to their access to other clients’ systems.

Retail & eCommerce

Retailers, especially smaller or niche e-commerce shops. These businesses often lack robust security teams, making them soft targets for credential harvesting and carding operations.

Healthcare & Industrial Automation

These organizations are attractive targets not just because of their mailing lists, but because of the trust associated with their brand identity. When an attacker sends an email from a legitimate MailChimp account tied to one of these domains, recipients are far more likely to open and engage with it.

Cookie Theft and MFA Bypass: A Silent Killer

Even when organizations implement MFA on their services (which, notably, isn’t universally enforced by organizations itself), attackers are finding ways in. One of the more alarming methods involves stealing authentication cookies through infostealers like RedLine, Raccoon, or Lumma, among others.

These cookies are then used to impersonate a logged-in session—allowing full access to accounts without ever needing to enter a password or second factor. It’s stealthy, effective, and often undetected until damage is done.

Constella’s Commitment

At Constella, we continuously monitor infostealer data, and exposed corporate credentials in real time. Our goal is to help businesses understand not only whether their data is exposed, but also what kind of attacks can originate from that exposure.

If your organization uses MailChimp, or if you suspect credentials may have been compromised in the past month, it’s time to take action. The threat is real, active, and spreading fast.

In today’s digital age, ransomware attacks have escalated to unprecedented levels, threatening businesses of all sizes and industries. The attack on the British logistics firm Knights of Old Group (KNP Logistics) in 2023 is a grim reminder of how devastating these attacks can be. Once a thriving company with a 150-year legacy, Knights of Old was forced to cease operations due to a crippling ransomware attack, displacing over 700 employees and ending decades of business continuity.

The Fall of Knights of Old: A Timeline of Devastation

According to The Times, the attack on Knights of Old began on June 26, 2023, when threat actors infiltrated the company’s network. The attackers, leveraging stolen credentials, gained access to sensitive systems and deployed Akira ransomware. Their message, later posted online, highlighted their intention to publish the company’s corporate and customer data, further intensifying the pressure through double extortion tactics.

The attackers mocked the company, stating: “Delivering freight when you’re a knight is not as convenient. Perhaps Knight’s honor prevented them from contacting us to discuss the data we got from their network. We will share their corporate information here. There is also a database with customers’ data. Everything will be uploaded soon.”

Despite adhering to international data security standards and having cyber insurance, Knights of Old could not recover from the operational and reputational damage inflicted by the attack. By September 2023, the company had ceased operations entirely, marking a significant loss for the logistics industry.

The Rising Tide of Ransomware Attacks

The plight of Knights of Old is not an isolated incident. Ransomware attacks have surged globally, with a staggering 105% increase in incidents reported between 2022 and 2023, according to cybersecurity firm Sophos. Threat actors are becoming more organized, often using data harvested by infostealers to craft highly targeted attacks.

Infostealers, such as RedLine and Raccoon, have become critical tools in the ransomware supply chain. These malicious programs harvest login credentials, system information, and other sensitive data from compromised devices. This data is then sold on underground forums, providing ransomware gangs with the resources needed to infiltrate corporate networks.

A Growing List of High-Profile Victims

1. Colonial Pipeline (2021): Stolen VPN credentials allowed attackers to deploy ransomware, causing fuel shortages across the U.S.
2. CWT Global (2020): Attackers leveraged credentials from an infostealer to demand a $4.5 million ransom, later negotiated to $4.2 million.
3. Nvidia (2022): While primarily a data breach, the attackers used stolen data to threaten ransomware deployment.

The increasing collaboration between infostealer developers and ransomware operators highlights the importance of understanding the interconnected nature of these threats.

Lessons Learned from Knights of Old

The tragic downfall of Knights of Old underscores several critical lessons for businesses aiming to protect themselves from similar fates:

1. Invest in Proactive Security Measures: Advanced endpoint protection, continuous network monitoring, and robust incident response plans are essential.
2. Implement Multi-Factor Authentication (MFA): This can prevent attackers from using stolen credentials to access sensitive systems.
3. Conduct Regular Employee Training: Phishing remains a leading entry point for infostealers. Educating employees on recognizing and reporting suspicious activity is crucial.
4. Leverage Threat Intelligence: Monitoring the dark web for compromised credentials can provide early warning signs of potential attacks.
5. Backup Critical Data: Secure and offline backups ensure data recovery even if ransomware encryption occurs.

The Broader Implications of Ransomware’s Rise

The closure of Knights of Old is a stark example of how ransomware can dismantle even well-established organizations. As The Times article highlights, the global economy’s reliance on digital infrastructure has made businesses increasingly vulnerable to these attacks. With ransomware incidents growing in frequency and sophistication, no organization is immune.

Cybersecurity experts warn that the intertwining of infostealers and ransomware marks a new era of cybercrime. By selling harvested data to the highest bidder, infostealer operators fuel a cycle of exploitation that culminates in devastating ransomware attacks.

Conclusion

The fall of Knights of Old serves as a powerful reminder of the stakes involved in today’s cybersecurity landscape. Organizations must prioritize comprehensive defense strategies, recognizing that the cost of inaction is far greater than the investment in proactive measures.

Ransomware is not just an IT problem—it’s a business continuity crisis. By learning from incidents like Knights of Old, businesses can better prepare for the challenges ahead, ensuring their resilience in an increasingly hostile digital world.

While many associate financial hacks with stolen funds, recent incidents reveal a more complex landscape. Cybercriminals are increasingly targeting confidential employee information, which can lead to tailored phishing attacks, extortion, reputational harm, and internal disruptions within financial institutions. This blog continues our previous exploration of cybersecurity challenges in the banking and financial sector, focusing on recent breaches highlighting evolving threats to employees and customers.

The exposure of employee data—such as organizational roles, personal contact details, and work-related credentials—has become a lucrative asset for threat actors. This information enables attackers to craft convincing phishing campaigns, impersonate executives, and infiltrate critical systems. Beyond immediate financial risks, these breaches subject employees to extortion attempts, psychological distress, and potential damage to their professional reputations. Such scenarios not only harm individuals but also undermine trust in the organization as a whole.

For customers, the risks extend far beyond compromised accounts. Even when financial details remain secure, leaked personal information such as addresses, phone numbers, or account identifiers can enable identity theft and scams. Attackers often exploit this data to impersonate individuals, apply for loans, or facilitate broader fraud.

As these breaches grow in scale and sophistication, financial institutions face mounting pressure to safeguard not just customer accounts but the broader ecosystem of sensitive data. This analysis delves into recent breaches to shed light on these pressing issues and the proactive measures required to mitigate their impact.

Cyberattacks are becoming increasingly sophisticated, with cookie session hijacking emerging as a significant threat. This technique allows attackers to bypass even advanced security measures like multi-factor authentication (MFA), enabling unauthorized access to critical systems and user accounts. Infostealers, a category of malware designed to harvest sensitive information, have become a primary tool for conducting these attacks. This blog explores how infostealers facilitate cookie session hijacking, its implications for organizations, and how businesses can defend against this evolving threat

How Cookie Session Hijacking Works

Cookie session hijacking is a process in which attackers steal and reuse session cookies to impersonate authenticated users. Here’s how the attack typically unfolds:

1. Initial Infection:
   1. Attackers use infostealers, phishing emails, or other malicious techniques to compromise a user’s device.
   1. Infostealers like RedLine, Racoon, Vidar, Meta, and Lumma are commonly deployed to harvest session cookies from compromised devices.
2. Cookie Extraction:
   1. Once the device is infected, the infostealer accesses the browser’s database to extract session cookies.
   1. These cookies are stored locally on the system, typically in locations like %localappdata%\Google\Chrome\User Data\Default\Cookies.
   1. Advanced tools like Mimikatz can decrypt protected cookies.
3. Session Hijacking:
   1. Stolen cookies are imported into the attacker’s browser using tools like “Cookie Quick Manager” (Firefox) or “cookies.txt importer” (Chromium-based browsers).
   1. The attacker now gains access to authenticated user sessions without needing credentials or MFA tokens.

• Exploitation:
  • Attackers leverage hijacked sessions to gain unauthorized access to critical systems, such as cloud administration consoles, collaboration platforms, and web-based email services.

• This access can facilitate further attacks, including data exfiltration, lateral movement within networks, or ransomware deployment.

Real-World Vulnerabilities Exploited Through Cookie Session Hijacking

Cookie session hijacking poses significant risks across most of the platforms and industries, so it is not limited to niche applications. We have tested and discovered vulnerabilities in many commonly used services:

• Email Services (including corporate emails)
  • Web-based email services are one of the most critical assets attackers seek to compromise. By hijacking session cookies, threat actors can bypass traditional authentication, gaining access to email accounts without needing the user’s password or two-factor authentication codes. This access level allows attackers to monitor and even exfiltrate sensitive data, conduct spear-phishing campaigns, reset passwords for other linked services, or impersonate the victim in business correspondence. The repercussions are severe, ranging from data breaches to financial fraud, as attackers use compromised email accounts to pivot and gain access to more valuable assets.

• Collaboration and Productivity Tools
  • With the rise of remote work, collaboration platforms like Slack, Microsoft Teams, and Google Workspace have become indispensable. Unfortunately, these tools are also vulnerable to cookie hijacking. Attackers who gain access to these sessions can infiltrate internal company communications, steal sensitive documents, and even disrupt workflows. This not only compromises the integrity and confidentiality of internal discussions but can also provide attackers with insights into project timelines, corporate strategies, and employee details, setting the stage for further attacks, such as ransomware or insider threats.

• Cloud Administration Consoles
  • Perhaps the most concerning are attacks targeting cloud administration consoles. These consoles provide deep access to a company’s digital infrastructure. Hijacked sessions here allow attackers to potentially manipulate cloud resources, disrupt services, or even delete critical infrastructure. The potential damage ranges from service outages to complete data loss, making cloud environments a prime target for sophisticated threat actors.

• AI Tools like ChatGPT
  • AI tools, such as ChatGPT, have also become targets for cookie session hijacking. Attackers who hijack sessions of AI tools can impersonate users and access sensitive conversations, which may include proprietary or confidential information.

• Social Media and Messaging Platforms
  • Many popular social media and messaging platforms are particularly vulnerable to cookie-based session hijacking. These platforms often allow users to replicate sessions across devices without requiring additional validation. This convenient feature, intended for user experience, becomes a weak point for security. Attackers who gain access to session cookies can use them to impersonate victims, gaining full access to their accounts, including private messages and sensitive interactions. This form of unauthorized access can lead to identity theft, social engineering attacks, or even brand impersonation to deceive contacts.

Implications for Organizations

Once attackers successfully hijack a session, they often move quickly to exploit the compromised account. For individuals, this can mean loss of privacy, unauthorized purchases, or fraudulent messages sent to contacts. For companies, the impact can be far more devastating:

• Corporate Espionage: Access to internal communication tools can reveal sensitive business strategies and negotiations.
• Financial Fraud: Compromised email or cloud accounts can lead to unauthorized transactions or blackmail.
• Supply Chain Attacks: Attackers can use hijacked sessions to impersonate company employees and target partners or suppliers, leading to a broader compromise of the supply chain.
• Data Exfiltration: Threat actors can use hijacked accounts to extract sensitive information, which is then sold or used for further attacks.

Introduction: Ransomware Landscape for Businesses

In recent years, ransomware has become one of the most pervasive cybersecurity threats, inflicting substantial losses on businesses globally. With an increasing number of organizations, from manufacturing to healthcare, falling victim to cyber extortion schemes, attackers are evolving their strategies to maximize impact. Notably, many of these attacks leverage infostealers—a type of malware designed to covertly harvest sensitive information, which is later used to facilitate ransomware operations. This blog delves into recent trends in ransomware, examining how cybercriminals exploit stolen data and the potential costs for organizations that become ensnared in these schemes.

Constella’s Analysis on Recent Ransomware and Data Exposures

Overview of Breaches and Infostealers

Ransomware attacks have escalated across various high-value industries, exploiting their unique vulnerabilities:

• Manufacturing:
  • Among the most affected sectors due to its reliance on complex data flows and interdependent supply chains.
  • Disruptions in this industry can lead to cascading operational failures across global supply networks.
• Healthcare:
  • A prime target for its critical systems containing life-saving information and sensitive patient data.
  • Ransomware in this sector poses heightened risks, as providers are often forced to pay ransoms to restore services promptly.
• Technology:
  • Targeted for its valuable intellectual property and business-critical information.
  • Breaches can disrupt innovation, compromise trade secrets, and damage competitive advantages, as well as compromise access to key security tools relied upon by other companies, amplifying the ripple effect of such attacks.
• Retail and Finance:
  • Cybercriminals exploit these sectors for their vast repositories of consumer data and financial assets.
  • Stolen data is often sold on the dark web or used for fraud and identity theft.

Ransomware incidents have a global footprint, with certain countries and regions experiencing elevated risks:

• United States:
  • The most affected country, facing frequent ransomware incidents across critical infrastructure, financial institutions, and healthcare systems.
  • Extensive digital connectivity and high concentrations of essential services make the U.S. an attractive target for cybercriminals.
  • Disruptions not only impact economic stability but also compromise key security platforms, potentially weakening defenses across industries.
• India:
  • Rapidly expanding digital infrastructure creates multiple vulnerabilities, offering attackers numerous points of entry.
  • Growth in technology and finance sectors increases exposure to ransomware threats.
• Canada, United Kingdom, and Australia:
  • These countries share similar dependencies on digital infrastructure as the U.S., making them attractive targets for cybercriminals.
  • Critical industries and public services in these nations are frequently disrupted by ransomware attacks, with increasing concerns about attackers exploiting security software providers.
• Germany:
  • A significant manufacturing hub, Germany’s strong industrial sector makes it particularly susceptible to supply chain disruptions caused by ransomware.
  • Breaches in Germany’s tech-driven industries could compromise tools essential for securing other companies, magnifying the impact of an attack.

The analysis further indicates that breaches involving stolen credentials—many gathered through infostealers—affect more than 86% of recently compromised companies. Specifically, 34.6% of breached organizations reported exposure to infostealer infections, illustrating how attackers infiltrate networks via seemingly legitimate entry points. This data underscores the necessity for robust cybersecurity measures to counteract these sophisticated threats.

How Infostealers Facilitate Ransomware Deployment Within Organizations

Infostealers play a pivotal role in ransomware operations, acting as the silent enablers that pave the way for attackers to infiltrate and compromise organizations. By harvesting credentials and other sensitive information, infostealers provide the initial access points necessary for deploying ransomware.

Infostealers frequently collect session cookies, allowing attackers to bypass authentication mechanisms entirely. This facilitates a rapid ransomware deployment process by giving attackers immediate access to critical systems without triggering security alerts.

On the other hand, infostealers extract credentials for VPNs, remote desktops, email accounts, and administrative tools. These credentials are often used to bypass security measures, such as firewalls and multi-factor authentication, granting attackers unrestricted access to an organization’s internal systems. Once inside, they can escalate privileges and move laterally across the network to identify valuable data and critical systems.

Below are real-world examples that highlight how infostealers are weaponized to infiltrate various organizational systems:

• VPN Access:
  Compromised VPN credentials can grant hackers a secure entry point into a company’s internal network. A notable example is the $22 million Change Healthcare ransomware incident, where attackers leveraged stolen VPN credentials to infiltrate the network, escalate privileges, and exfiltrate sensitive data before executing the ransomware.

• Corporate Webmail:
  Hackers exploit stolen email credentials to extract confidential information from employee mailboxes. A high-profile case involved the Argentine police, where hackers obtained over 12,000 police contact details using compromised webmail access.

• Collaboration Tools:
  Platforms like GitHub, Confluence, and Slack house critical company data. The EA Sports breach, which resulted in the theft of 780 GB of source code, exemplifies the risks associated with infostealer-compromised collaboration accounts.

• Cloud Services:
  As businesses increasingly rely on cloud platforms, credentials for AWS, GCP, and Azure have become prime targets. A large-scale breach involving Snowflake impacted 165 organizations, including major firms such as AT&T, affecting millions of end users worldwide.

Economic Impact and Costs of Ransomware Attacks

The financial toll of ransomware extends beyond ransom payments, impacting business operations, customer trust, and regulatory compliance. In the case of Change Healthcare, the breach’s overall cost reached an estimated $22 million. Globally, ransomware has already cost organizations billions, with damages encompassing lost productivity, legal fees, and system recovery expenses. The threat is also reputational, as customers and stakeholders scrutinize data protection efforts following a breach.

In today’s digital landscape, protecting your identity from real-time threats is more critical than ever. As a cybersecurity expert, I’ve seen an evolving spectrum of threats that go far beyond traditional identity theft. From classic dark web doxing to the advent of fullz—full identity kits sold for a few dollars—threat actors are leveraging these methods for a new breed of real-time scams, amplified by cutting-edge technology.

Recently, a project by Anh Phu Nguyen  and Caine Ardayfio demonstrated the capability to integrate facial recognition technology with Meta’s smart glasses, allowing instant identification of strangers. This development marks a significant leap from the traditional static forms of identity theft into real-time exploitation, where personal information is weaponized in the moment.

Classic Doxing and Fullz on the Dark Web

For decades, doxing and the sale of fullz (complete identity kits) have been staple methods of cybercriminals on the dark web. Doxing involves collecting and publicizing personal information such as home addresses, phone numbers, and social media profiles, often with the intent to embarrass, harass, or intimidate. OSINT tools (Open-Source Intelligence) allow attackers to scrape social media profiles, public databases, and breached datasets to compile detailed profiles on their victims. Once exposed, this data is used for targeted harassment or extortion.

Meanwhile, fullz provide a more comprehensive set of personal details, typically including social security numbers, financial data, and other sensitive information that can be exploited for identity theft. The sale of fullz on dark web marketplaces has enabled identity theft and financial fraud on a massive scale. For a relatively small fee, threat actors can purchase a victim’s entire identity, making it easy to perform account takeovers, create fake profiles, or apply for credit in the victim’s name.

In the past, these methods were effective but static. Attackers could steal and use personal data long after it was exposed. Today, however, advancements in technology have transformed these identity theft techniques into dynamic, real-time threats.

Real-Time Identity Exploitation: The New Era of Scams

The rise of facial recognition technology combined with wearable devices, like Meta’s smart glasses, introduces a new dimension to identity theft. By pairing this real-time data collection with pre-existing fullz or other doxing techniques, threat actors can instantly exploit an individual’s identity on the fly.

In this I-XRAY demonstration, Meta’s smart glasses were modified to scan faces in public, instantly cross-referencing them with public social media data and possibly with compromised identity information. Imagine walking down the street, unaware that someone can identify you, access your data, and target you with personalized scams—all in real time. This shift turns identity theft into a real-time, hyper-targeted activity.

Here’s how this modern version of doxing and scamming might unfold:

• Real-time recognition: A malicious actor equipped with facial recognition on smart glasses could walk through crowded public spaces and instantly identify individuals based on a match with their leaked photos from social media or other sources. This is no longer hypothetical; the proof-of-concept has already been demonstrated.

• Instant exploitation: Once an individual is identified, scammers could access their leaked fullz from the dark web, providing them with a detailed set of personal information. They could then approach the target in real-time, pretending to know them, creating a social engineering scenario where the victim believes the scammer is a legitimate acquaintance or authority figure.

• On-the-spot phishing: Imagine being approached by someone who knows your full name, email, address, and the last few digits of your social security number. When they ask you to verify some information the victim could easily fall into the trap of handing over even more sensitive information—like bank account details—without realizing they’ve been scammed until it’s too late.

The Role of AI in Amplifying Real-Time Threats

AI plays an integral role in the future of identity scams. It allows for the rapid analysis and deployment of identity data, enabling new, sophisticated scams that were previously unimaginable. Here are several ways AI can enhance these real-time threats:

• AI-Powered Deepfakes: Threat actors can combine AI-generated deepfakes with real-time data to impersonate individuals in both video and audio formats. By using AI to craft believable but fake messages or phone calls, scammers can extort or deceive people more convincingly than ever before.
• Automated Identity Theft at Scale: AI tools can automate the collection and correlation of personal data across multiple sources—social media, leaked data, and public records—faster than any human could. This allows threat actors to assemble profiles on victims quickly, accelerating identity fraud.
• Behavioral Analysis and Predictive Attacks: AI can analyze online behaviors to predict the types of scams most likely to succeed on a given target. For example, someone frequently searching for job opportunities could be targeted with a fake job offer, exploiting the victim’s immediate needs.

In recent weeks, underground forums on the dark web have continued to flourish as bustling marketplaces where cybercriminals sell unauthorized access to corporate networks. From VPN credentials to Remote Desktop Protocol (RDP) access, threat actors take advantage of compromised corporate environments, often leveraging data from recent breaches or stolen via infostealers. This analysis highlights the trends observed in the last few weeks, shedding light on the types of actors involved, the most targeted countries and sectors, and the types of access being traded.

Selling Access to Corporate Networks Through Key Actors on Underground Forums

In just the last few weeks, over 250 distinct threat actors have been identified on underground forums, all involved in selling access to corporate networks. These actors can be divided into two major categories:

• Individual cybercriminals – Typically specializing in phishing attacks or leveraging malware like infostealers, these individuals focus on lower-value or opportunistic attacks.
• Organized cybercrime groups – These structured groups act as access brokers, offering extensive credential dumps and long-term, persistent access to corporate environments. Their capabilities are far more advanced, often involving sophisticated breaches and after-sale services to ensure buyers can maximize the value of the access.

Breakdown of Threat Actors:

• 60% of the identified actors are individuals, concentrating on smaller, low-value targets, often selling low-risk access points.
• The remaining 40% are part of coordinated cybercriminal groups, focusing on high-value targets with comprehensive access that often includes post-sale support like lateral movement within networks and privilege escalation.

These actors don’t just stop at initial access. A significant number of them provide additional services, such as helping buyers navigate through compromised corporate systems and avoid detection. The after-sale support offered by these groups often includes technical assistance to move laterally within the network and maintain persistent access, ensuring attackers can continue exploiting their entry points over time.

The data from just a few weeks offers a window into the vast and diverse ecosystem of cybercrime thriving on underground forums. This highlights the rapidly evolving nature of these threat actors and underscores the need for corporations to stay vigilant against an ever-growing array of cyber threats.

The persistent activity observed emphasizes the continuous development of more advanced methods to breach and exploit corporate environments, making it clear that cybersecurity must remain a top priority for organizations across all sectors.

Most Targeted Countries

Recent data from underground forums shows that threat actors are targeting companies and institutions across multiple continents, with a clear focus on high-value sectors like finance, technology, government, and energy. Here’s a summarized breakdown of the affected countries and continents:

North America

• United States: Primarily targets in the financial and technology sectors.
• Canada: Focus on financial and real estate sectors.
• Mexico: Targets include government agencies and financial services.

Europe

• Russia: Focus on energy and government sectors.
• Poland: Targets in the manufacturing sector.

Recent Data Trends in Cybercriminal Targeting & Selling Access to Corporate Networks

The latest data from underground forums indicates a growing focus on three main sectors: finance, education, and real estate. These sectors are increasingly becoming targets for cybercriminals, primarily due to the wealth of sensitive information they hold and their operational importance.

Finance Sector

Access to financial services firms has become one of the most common offerings on underground forums. Financial institutions are especially vulnerable because they manage vast amounts of sensitive data, from customer information to transaction details. This data is not only valuable for direct financial gain but also for long-term exploitation, such as fraud and identity theft.

Threat actors are selling access to financial organizations, particularly banks and investment firms, that control billions in assets. These listings often include VPN and RDP access to corporate networks, allowing attackers to infiltrate the system and potentially deploy ransomware or steal sensitive data. Cybercriminal groups see this as a high-return opportunity, especially since financial institutions are often willing to pay ransoms to recover their operations quickly.

Education Sector

Educational institutions, particularly large universities with many employees and students, are becoming frequent victims of cyberattacks, especially ransomware. Schools and universities hold sensitive intellectual property, personal student data, and research information, making them attractive targets. Attackers frequently exploit this data by using stolen credentials obtained from phishing or malware campaigns. Once inside, they can lock down critical systems and demand a ransom, often crippling educational services and access to essential resources.

This rise in attacks on educational institutions aligns with the broader trend of ransomware-as-a-service (RaaS), where organized cybercriminal groups offer ransomware to affiliates, who then launch attacks and split the ransom payments. Educational institutions, especially those involved in cutting-edge research or government-sponsored projects, are prime targets for these sophisticated, high-impact ransomware campaigns.

Real Estate Sector

The real estate sector is another emerging target for cybercriminal groups, with listings for real estate firms becoming more common. These companies hold critical data on property ownership, transactions, and financial dealings, making them attractive to attackers seeking to steal valuable information or disrupt operations. The real estate industry also relies on secure networks to manage large transactions and sensitive communications, further making it a target for ransomware and data exfiltration.

Ransomware-as-a-Service (RaaS) Influence

Organized cybercriminal groups are increasingly using RaaS to monetize stolen data. This model allows cybercriminals to sell access or share ransomware tools with affiliates who conduct the attacks, splitting profits with the developers of the ransomware. The shift toward this model has lowered the barrier to entry for cybercriminals, allowing even low-skilled attackers to participate in high-impact attacks. Institutions in the finance, education, and real estate sectors are prime targets for RaaS-based attacks because of the high potential for extortion, intellectual property theft, and operational disruption.

Overall, the convergence of RaaS with sector-specific targeting demonstrates how organized cybercrime is evolving, with specialized groups focusing on high-value sectors that are more likely to pay ransoms or suffer significant disruptions from attacks.

Links to Public Breaches and Infostealers

Much of the data traded for corporate access originates from well-publicized breaches or is harvested via infostealers. These infostealers, like Vidar and Redline, are frequently used to siphon login credentials from compromised devices. These credentials are then sold in bulk on underground forums or offered as part of access packages.

One prominent example is the sale of credentials linked to a breach at a North American financial institution. The listing offered RDP access to the company’s network, likely obtained through a combination of phishing and infostealer malware. Similarly, credentials linked to healthcare organizations and university networks in the U.S. and Canada have been offered for sale, highlighting how infostealers play a critical role in these underground economies.

Types of Access Sold

The most commonly sold types of access on these forums include VPN credentials, RDP access, and increasingly, cloud platform access. VPN credentials allow buyers to gain access to secure corporate networks by bypassing firewalls, while RDP access grants full control over a target machine, allowing attackers to move laterally within the system and escalate privileges.

Cloud platform access is also becoming more prevalent as companies move critical infrastructure to cloud services like AWS and Azure. Listings advertising admin access to a company’s cloud infrastructure, such as AWS environments, have attracted interest, as cloud-based environments represent a significant attack surface for organizations.

The Importance of Comprehensive Corporate Protection

Many of the cyberattacks observed on underground forums are rooted in data obtained from data breaches or infostealers, highlighting the urgent need for organizations to expand their security focus beyond traditional corporate credentials. While many companies concentrate their defenses on securing credentials from corporate devices, cybercriminals do not discriminate between data obtained from corporate or personal devices. Their sole interest is in accessing valuable data from targeted or attractive companies.

For threat actors, it doesn’t matter if credentials were compromised on a work-issued laptop or a personal device; as long as the credentials grant access to sensitive corporate systems, they are of high value. This means that companies must protect all potential entry points—both professional and personal. Employees often use the same passwords across platforms or access corporate resources from personal devices, creating a significant vulnerability.

On the other hand, there is another important issue because many organizations continue to rely heavily on Multi-Factor Authentication (MFA) and VPN solutions as their primary security mechanisms. However, recent studies, such as those by Constella Intelligence, have demonstrated that these protections are no longer as foolproof as once believed. Infostealers—malware designed to harvest login credentials and other sensitive information—have proven effective at bypassing these security measures. Threat actors can use stolen data to circumvent both MFA and VPN mechanisms, rendering them ineffective against sophisticated attacks.

In particular, infostealers can capture session tokens, cookies, and authentication tokens that allow attackers to bypass MFA entirely. Even if a corporate system requires two-factor authentication, attackers can replay these tokens to gain unauthorized access. Likewise, VPN protections can be bypassed if attackers obtain the necessary credentials and tokens, allowing them to enter corporate networks as legitimate users without raising red flags.

This growing threat underscores that, while MFA and VPNs are important components of a security strategy, they can no longer be the sole lines of defense. Organizations need to adopt more advanced security measures that address the vulnerabilities exposed by credential-based attacks.

The geopolitical conflict between Israel and its adversaries has shifted into the digital sphere, where sophisticated cyberattacks have become a primary tool for targeting critical sectors. In recent months, cyberattacks have exposed Israeli defense data, diplomatic communications, and sensitive civilian information. Among the prominent players in this cyberwarfare is the Handala Group, a hacktivist entity leveraging advanced persistent threat (APT) tactics to disrupt Israeli operations. Other actors, such as EagleStrike and the Hunter Killer hacker group, further complicate Israel’s cybersecurity landscape.

The digital world has revolutionized the way we live and work, but it has also opened up a new realm for cybercriminals. The rise of the dark web has provided a breeding ground for hackers and other malicious actors to trade stolen data and launch attacks against companies worldwide. This blog post provides a summary of some of the trends observed over the past few days, highlighting how threat actors are using compromised data to exploit businesses, the sectors most impacted, and the dynamics of this underground market.

Cybercriminal’s Hidden Market for Stolen Data

Imagine an underground marketplace bustling with activity — vendors selling hacked streaming service accounts, buyers bidding on cloud storage credentials, and a community exchanging tips on how to bypass security features. This is the reality of the dark web, where forums like BreachForums act as virtual bazaars for compromised data.

Stolen information is incredibly valuable in this shadowy ecosystem. From streaming service logins to financial account credentials, threat actors peddle a variety of digital goods. But why is there such a demand? The answer lies in the sheer usability of this data — for unauthorized access, fraud, identity theft, or even blackmail.

Which Sectors Are Being Targeted the Most?

Recent activity on underground forums reveals a worrying trend: threat actors are targeting multiple industries. The most affected sectors include digital services, cloud storage platforms, and financial services, reflecting a shift in focus towards companies that hold valuable user data and offer high resale value.

1. Digital Services and Streaming Platforms:

• Who’s at Risk? Companies like Netflix and Disney+ are prime targets. Their popularity and the fact that millions of users are willing to pay for premium content make them attractive for hackers.
• What’s Being Sold? Compromised accounts are often shared or sold with details like session cookies, making it easy for buyers to bypass login security. This enables users to enjoy premium services without the account owner’s knowledge.

The fight against cybercrime is ongoing, and understanding how threat actors operate is the first step in protecting our digital assets.

By shedding light on these dark activities, we hope to raise awareness and help companies build stronger defenses against the ever-evolving threat of compromised data.

Infostealers are specialized malware designed to extract sensitive data from infected systems. They operate in the background, collecting login credentials, browser histories, and cookies, often without detection. Deployed through phishing emails or malicious websites, infostealers are a growing favorite among cybercriminals due to their low risk of detection and the high-value data they yield.

Unlike more overt forms of cyberattacks like ransomware, infostealers are subtle and continuous. The stolen information is often sold in bulk on dark web marketplaces or used to launch further attacks, such as gaining access to company networks or committing financial fraud. The sophistication of these tools has grown, making them one of the most effective methods for threat actors to compromise corporate environments.

Why Infostealers Are Effective Against Companies

Infostealers are attractive to threat actors for several reasons:

1. Low Detection Rates: Infostealers are designed to evade detection by traditional security measures such as antivirus software. Once deployed, they blend seamlessly into legitimate system processes, making it challenging for conventional security solutions to recognize or remove them. This stealth allows them to operate undetected for extended periods, gathering critical data.

• Targeting High-Value Data: Infostealers are capable of extracting a wide range of sensitive information, including passwords, session cookies (which can be used to bypass multi-factor authentication), financial records, and proprietary business data. This stolen data is often sold on dark web marketplaces or used for extortion, leading to significant financial and reputational damage.

• Wide Availability and Accessibility: Infostealers are readily available for purchase on dark web forums, frequently offered as part of malware-as-a-service (MaaS) platforms. This makes them accessible even to less experienced cybercriminals, lowering the barrier to entry for launching sophisticated attacks. The ease of access and customization further amplifies their appeal to threat actors across the cybercriminal ecosystem.

Top Threat Actors Leveraging Infostealers

We have seen that many cybercriminals are actively using infostealers data as a preferred method for infiltrating organizations. These groups have leveraged infostealers to breach companies, leading to extensive financial and reputational damage. Below are a number of threat actors that stand out for their sophisticated use of these tools:

• USDoD: This threat actor has carried out high-profile attacks, including the breach of Airbus by exploiting compromised credentials from a Turkish Airlines employee. This attack underscores the significant risk that infostealers pose to supply chains, allowing hackers to penetrate companies through vulnerable third-party partners​.
• Sp1d3rHunters: Known for exploiting Snowflake accounts, Sp1d3rHunters has executed breaches against major companies such as Ticketmaster and AT&T, exfiltrating sensitive data such as customer information and event tickets. Their operations demonstrate how infostealer logs can be used to gain access to cloud services and wreak havoc​.
• IntelBroker: This notorious threat actor has breached both government and private sector entities, targeting organizations such as Apple, Zscaler, and Microsoft. By using Infostealer-collected credentials, IntelBroker has facilitated attacks on critical infrastructure and sold access to compromised systems on dark web forums, further intensifying the risk to companies​.
• Andariel (North Korea): Part of the Lazarus Group, Andariel is a North Korean state-sponsored Advanced Persistent Threat (APT) actor. This group is known for using infostealers, alongside other tools like keyloggers and remote access trojans (RATs), to target sectors such as military, nuclear, and manufacturing. Andariel’s strategy of using Infostealers to gather intelligence and financial data is a key part of their cyber operations​.
• Lapsus$: Emerging in 2021, Lapsus$ has quickly gained a reputation for its high-profile breaches of companies like NVIDIA, Samsung, and Vodafone. Lapsus$ utilizes info stealers to harvest login credentials, payment information, and proprietary business data. In a notable attack, Lapsus$ breached Electronic Arts (EA), stealing source code for popular games like FIFA. The group’s aggressive tactics have caused widespread disruption in the tech and financial sectors​.

These groups’ sophisticated use of infostealers illustrates why businesses must adopt more advanced detection and monitoring systems to protect against this growing threat.

How Companies Can Defend Against Infostealers

While info stealers present a complex threat, companies can adopt several key strategies to mitigate the risks and minimize the impact of such attacks:

• Analyze Exposed Data for Risk Mitigation: After a suspected infostealer attack, companies must conduct thorough analyses of the stolen data to assess the potential risks. This includes examining session cookies that could be hijacked to bypass multi-factor authentication (MFA), as well as personal credentials that may be used to impersonate employees or escalate privileges within the organization. Proactively identifying and addressing these risks can help prevent follow-up attacks or unauthorized access.

• Strengthen Authentication Practices: While MFA is an essential safeguard, it is not foolproof, especially if session cookies are compromised. Companies should implement adaptive MFA, which monitors for anomalies in login attempts (such as unusual locations or devices) to prevent attackers from using stolen credentials. Additionally, frequent reauthentication can help disrupt the use of stolen session tokens.

• Monitor for Unusual Access Patterns: Regularly reviewing access logs and monitoring for anomalous login attempts—such as multiple failed attempts, logins from unexpected locations, or odd behavior patterns—can help detect infostealer activity early. Endpoint Detection and Response (EDR) systems can play a key role in identifying and mitigating the effects of infostealers by flagging unusual data access or exfiltration activities.

• Educate Employees on Phishing and Cyber Hygiene: Many infostealers are deployed through phishing attacks or malicious links. Regularly training employees to recognize suspicious emails, websites, and attachments can significantly reduce the likelihood of an initial infection. Implementing phishing simulations and real-time feedback can help maintain employee vigilance.

In recent years, the landscape of cyber scams has evolved, targeting even the tools designed to protect consumers. One such concerning development involves the exploitation of trusted services to mislead and scam users. This article explores a specific case in which scammers may have taken advantage of these services to deceive users into divulging sensitive information, leading to potential financial losses and identity theft.

The Mechanics of the Cyber Scams

At the core of this issue lies a highly sophisticated cyber scam that exploits the trust consumers place in services that were designed to alert users regarding suspicious activities or data breaches. In this case, however, scammers have managed to breach the very systems intended to safeguard user identities. Here’s how the scam operates:

1. Compromised Alerts: Users receive seemingly legitimate alert emails from a trusted organization, notifying them of potential security issues. These emails include clickable links that direct users to what appear to be secure websites.
2. Redirects to Malicious Sites: Upon clicking the link, users are redirected to malicious domains designed to look like legitimate websites or are taken directly to scam sites hosted on platforms like Telegram. These sites may request further sensitive information under the guise of security checks or offer downloads that contain malware.
3. Exploitation of User Trust: The effectiveness of this scam lies in its exploitation of user trust. Since the alerts originate from a trusted source, users are more likely to click on the links without their usual level of scrutiny. This bypasses standard phishing detection mechanisms, which often filter out emails from suspicious or unknown sources.

Indicators of Deceptive Practices

Several red flags were identified during the investigation into these compromised alerts:

• Clickable Links in Alerts: Unlike more secure practices adopted by other identity protection services, some alerts include clickable links. This practice is risky because it can easily be exploited to redirect users to malicious sites.
• Use of Scam Domains: The domains used in these alerts were found to be registered for the explicit purpose of hosting scam operations. For example, one domain redirected users to a Telegram channel that further directed them to malicious downloads or additional scams.
• High Click-Through Rates: Analysis of traffic to these scam domains revealed a substantial number of users clicking through from these alerts. This suggests a significant exploitation of these alerts, driving traffic to malicious sites and potentially resulting in a high number of compromised users.

Potential Implications and Risks of Cyber Scams

The consequences of this scam could be far-reaching:

• Financial Loss: Users deceived by these scams might inadvertently provide sensitive information such as banking details, leading to financial fraud or unauthorized transactions.
• Identity Theft: The exposure of personal information can lead to identity theft, where attackers use the information to open new accounts, make purchases, or engage in other forms of fraud.
• Malware Infections: Users who download files from these scam sites could infect their devices with malware, further compromising their security and potentially leading to data loss or additional breaches.
