A Tennessee man accused of abusing and sexually exploiting children while actively participating in 764, a sprawling online nihilistic violent extremist collective affiliated with The Com, pleaded not guilty Thursday to a series of charges that could keep him locked up for 50 years.

Zachary Sweeney has allegedly victimized multiple children, on numerous occasions grooming and coercing minors to produce child sexual abuse material that he distributed and sometimes sold, the Justice Department said. One of the 30-year-old’s alleged victims later died of an overdose.

Sweeney has been the subject of multiple FBI investigations, which uncovered extensive crimes against children dating back to at least 2022, prosecutors said. His alleged involvement in 764 and, by extension, The Com, underscores the growing, multi-faceted threat of physical violence, cybercrime, extortion and the pursuit of criminal underground notoriety posed by thousands of members typically between 11 and 25 years old.

Victims of these crimes are often young, vulnerable and degraded or traumatized for years with life-altering impact.

“Violent extremists who victimize vulnerable children online are among the worst predators in our community and across the country,” Braden Boucek, U.S. attorney for the Middle District of Tennessee, said in a statement.

Members of 764 and related groups commit crimes in the United States and engage with other extremists globally to foment social unrest and destroy civilized society through the corruption and exploitation of vulnerable people, the Justice Department said.

Police arrested Sweeney Thursday and charged him with three counts of sexual exploitation and attempted sexual exploitation of a minor and three counts of receiving visual depictions of CSAM. Prosecutors said they intend to request Sweeney remain detained at his next court appearance June 3. 

Sweeney allegedly traveled to New York, Indiana, Missouri and Georgia to meet numerous victims in person. Officials received reports from some of his alleged victims and online platforms, triggering FBI interviews with some of his alleged victims as early as 2023. 

One of his alleged victims, who began interacting with Sweeney when she was a teenager, told investigators she degraded herself and participated in virtual self-harm group video calls with a group of people she described as friends of his in The Com. Sweeney alleged raped her and streamed the crime online. 

She died of an overdose in 2024, approximately ten days after FBI agents interviewed her. 

Sweeney allegedly drugged and raped other victims and shared videos of those acts online, according to court records.

The FBI searched Sweeney’s residence in St. Louis in September 2023, more than two months after Meta sent a pair of tips to the National Center for Missing and Exploited Children that linked him to Instagram chats containing CSAM.

Agents seized devices containing evidence of 99 possible CSAM images and videos, but encryption and passwords prevented authorities from conducting further examination, according to court records.

Sweeney moved to Tennessee in the summer of 2024 and allegedly continued to travel out of state to meet victims in person and coerce other victims to produce CSAM through at least the summer of 2025.

Authorities accuse Sweeney of boasting about his crimes and sharing blackmail material, sexual assault and CSAM depicting underage female victims.

Authorities have arrested multiple members of 764 during the past year, reflecting heightened law enforcement activity targeting the violent extremist collective and other offshoots affiliated with The Com.

Two alleged leaders of 764, Leonidas Varagiannis and Prasan Nepal, were arrested and charged for directing and distributing CSAM in April. Alexis Aldair Chavez, of San Antonio, pleaded guilty in December to multiple crimes involving the sexual exploitation of children while acting as an administrator and leader of 8884, a splinter group of 764.

“This operation puts every child predator on notice: the FBI will hunt you down and bring you to justice,” Terence Reilly, special agent in charge of the FBI Nashville Field Office, said in a statement. “Removing violent extremists from our streets protects our most innocent and vulnerable members of society.”

Instructure, the company behind Canvas, said it reached an agreement with the cybercriminals who threatened to leak a trove of sensitive data they claim was stolen during a prolonged cyberattack on the widely used education tech platform.

Pressure was mounting on the company as widespread outages left schools, students and teachers temporarily unable to access critical data late last week when the company took Canvas offline after the attackers defaced the platform’s login page. By Friday, the company said Canvas — a central hub for K-12 and university coursework, exams, grades and communication — was back online and fully operational. 

ShinyHunters, a decentralized crew of prolific cybercriminals that researchers affiliate with The Com, claimed responsibility for the attack on its data leak site and was attempting to extort the company for an unknown ransom amount. 

Instructure didn’t outright say it paid a ransom, but insisted the agreement provided all necessary assurances. “The data was returned to us. We received digital confirmation of data destruction (shred logs),” the company said in an update Monday.

“We have been informed that no Instructure customers will be extorted as a result of this incident, publicly or otherwise,” the company added. “This agreement covers all impacted Instructure customers, and there is no need for individual customers to attempt to engage with the unauthorized actor.”

The threat group initially set a deadline of May 6 — four days after Instructure previously said the incident was contained — claiming it stole 3.65 terabytes of data spanning 275 million records across 8,809 school systems. 

When that deadline passed without payment, ShinyHunters escalated its pressure on the company by “injecting an extortion message directly into the Canvas login pages of roughly 330 institutions, and pivoted to school-by-school extortion with a current deadline of May 12,” Cynthia Kaiser, senior vice president of Halcyon’s Ransomware Research Center, told CyberScoop.

The additional public pressure prompted Infrastructure to take Canvas offline, disrupting schoolwork and access to critical systems nationwide. 

Instructure CEO Steve Daly apologized over the weekend for the company’s inconsistent communication and deficient public response to the cyberattack. 

“Over the past few days, many of you dealt with real disruption. Stress on your teams. Missed moments in the classroom. Questions you couldn’t get answered. You deserved more consistent communication from us, and we didn’t deliver it. I’m sorry for that,” he said in a statement.

Daly acknowledged that the attack, which remains under investigation aided by CrowdStrike, exposed usernames, email addresses, course names, enrollment information and messages. He insisted that course content, submissions and credentials were not compromised.

The temporary but widespread disruption has spurred broad concern across the education sector as ransomware experts and threat hunters continue to track developments. The cyberattack also caught the attention of lawmakers on Capitol Hill. 

The House Homeland Security Committee on Monday published a letter to Daly seeking a briefing with him or a senior leader at Instructure by May 21. 

“The recurrence of an intrusion within days of an initial breach disclosure, and Instructure’s apparent failure to fully remediate the underlying vulnerabilities during that window, raise serious questions about the company’s incident response capabilities and its obligations to the institutions and individuals whose data it holds,” House Homeland Security Chairman Andrew Garbarino, R-N.Y., wrote in the letter to Daly.

The committee wants to learn more about the “circumstances of both intrusions, the the nature and volume of data accessed, the steps Instructure has taken and is taking to contain the threat and notify affected institutions, and the adequacy of the company’s coordination with federal law enforcement and the Cybersecurity and Infrastructure Security Agency,” he added. 

CISA did not describe the extent of its involvement in Instructure’s response. “CISA is aware of a potential cyber incident affecting Canvas. As the nation’s cyber defense agency, we provide voluntary support and cybersecurity services to organizations in responding to and recovering from incidents,” Chris Butera, the agency’s acting executive assistant director for cybersecurity, said in a statement.

Instructure’s timeline of the attack has changed and remains incomplete. The company said it first detected unauthorized activity in Canvas on April 29 and immediately revoked the attacker’s access and initiated an incident response. Researchers not directly involved with the formal investigation said ShinyHunters gained access to Canvas at least a few days earlier.

The follow-on malicious activity on May 7 — the defacement of public login pages — was tied to the same incident, the company said. 

“We have since confirmed that the unauthorized actor carried out this activity by exploiting an issue related to our Free-For-Teacher accounts. This is the same issue that led to the unauthorized access the prior week. As a result, we have made the difficult decision to temporarily shut down Free-For-Teacher accounts,” the company said in an updated post about the incident.

Instructure did not answer questions about the vulnerability or explain how attackers intruded its systems. The company said it also revoked privileged credentials and access tokens for affected systems, rotated internal keys, restricted token creation pathways, and deployed additional security controls and monitoring.

Canvas is fully operational and safe to use, the company said, adding that CrowdStrike has reviewed known indicators of compromise and “found no evidence that the threat actor currently has access to the platform.”

Access still remains spotty and unavailable for some Canvas users as school districts restore the platform in phases after conducting their own internal checks.

Halcyon published an alert about the attack Friday, including a screenshot of the message that some school staff, guardians and students encountered before Instructure took the learning management system offline.

ShinyHunters is a notorious data theft extortion group that previously hit major cloud platforms, including Salesforce and Snowflake, via voice phishing, credential theft and supply-chain attacks. 

Education is a recurring and consistent target for cybercriminals, accounting for more than 250 ransomware attacks globally last year, according to Halcyon. 

Yet, the scope of the attack on Canvas “makes this one of the largest single education-sector exposures we’ve tracked,” Kaiser said.

“By compromising a shared platform used across thousands of schools, ShinyHunters hit the entire education sector in one move, which is the same playbook Clop ran against Oracle EBS customers last fall,” she added. “Among 2026 incidents against critical infrastructure, this is at or near the top for education-sector impact, and it highlights a trend of third-party software vendors now being part of an attack surface, and causing cascading effects across an entire sector.”

Cybersecurity professionals focused on ransomware and data theft extortion consistently encourage victims to not pay ransoms, but they also often acknowledge that companies have to make tough decisions based on their own interests and the security of their customers or users caught up in the aftermath.

Allison Nixon, chief research officer at Unit 221B, said the threat group claiming responsibility for the attack should not be trusted. 

“They are claiming they will delete the data after they are paid, and if they are not paid that they will leak the data,” she told CyberScoop. “This is in line with the past data extortion scams run by the same and related Com actors, who have made false statements to victims and to the public in the past.”

Instructure acknowledged that its agreement with the attackers isn’t ironclad. “While there is never complete certainty when dealing with cybercriminals, we believe it was important to take every step within our control to give customers additional peace of mind, to the extent possible,” the company said.

Daly — a longtime security executive who was previously CEO at Ivanti — ended his mea culpa with a pledge to improve communications and provide a summary of a forensics report soon.

“Last week, we made a call to get the facts right before speaking publicly. That instinct isn’t wrong, but we got the balance wrong. We focused on fact-finding and went quiet when you needed consistent updates. You’ve been clear about that, and it’s fair feedback. We will change that moving forward,” he said. 

“Rebuilding trust takes time,” Daly added. “We’re going to earn it back through consistent action and honest communication.”

Update: May 12, 11:00 am: This story has been updated to reflect that Instructure announced they have reached a deal with ShinyHunters.

A pair of persistent and problematic threat groups affiliated with The Com are actively targeting organizations across multiple critical infrastructure sectors for rapid data theft and extortion attacks, according to CrowdStrike.

The financially-motivated attackers, which CrowdStrike tracks as Cordial Spider and Snarky Spider, have used voice-phishing and social engineering attacks to break into victims’ identity platforms and traverse SaaS environments since at least October 2025, the company said in a report Thursday, which it shared exclusively with CyberScoop prior to release. 

Adam Meyers, senior vice president of counter adversary operations at CrowdStrike, said the subgroups composed of native English speakers primarily target U.S.-based organizations in the academic, aviation, retail, hospitality, automotive, financial services, legal and technology sectors.

This “new wave of ecrime threat actors” are closely aligned with Scattered Spider and linked to other subsets of The Com, including SLSH and ShinyHunters, Meyers said. 

Because these attacks target identity systems and can expose data in other connected services beyond the initial breach point, it’s difficult to determine how many victims have been caught up in these campaigns. 

CrowdStrike’s warning closely follows research Palo Alto Networks’ Unit 42 and the Retail & Hospitality Information Sharing and Analysis Center shared last week about Cordial Spider’s string of attacks targeting organizations in the retail and hospitality industry, among others. 

Cordial and Snarky Spider have set lures via voice calls, text messages and emails directing targeting employees to phishing pages posing as their employer’s legitimate single sign-on page or primary identity provider, researchers said. 

These phishing pages, which capture credentials, session keys or tokens, depending on the workflow, provide attackers an entry point into systems, which they exploit for widespread access across victims’ entire SaaS ecosystems.

Attackers use these initial hooks to remove and establish multi-factor authentication devices, then delete emails and other alerts that would otherwise warn organizations of potential malicious activity, researchers said. 

The data theft for extortion campaigns share striking similarities, but CrowdStrike said the tactics, techniques and procedures for each subgroup are distinct. These variances include hours of operation, different phishing domain providers, preferred operating systems, data leak sites, and the tools or devices they used to register for multi-factor authentication. 

The domain for BlackFile, Cordial Spider’s data-leak site, was offline as of Wednesday, according to Meyers.

CrowdStrike declined to put a range on the groups’ extortion demands, but Unit 42 previously said Cordial Spider, which is also tracked as CL-CRI-1116 and UNC6671, are typically in the seven-figure range.

Some victims that didn’t pay extortion demands have been subjected to DDoS attacks, and Snarky Spider has used more aggressive follow-on harassment tactics, including the swatting of victim organizations’ employees, Meyers said. 

CrowdStrike said Cordial and Snarky Spider also use residential proxy networks — including Mullvad, Oxylabs, NetNut, 9Proxy, Infatica and NSOCKS — to evade IP-based detection and blend in with typical traffic. 

Residential proxy networks, which rely on IP addresses assigned to real home users, can serve a legitimate purpose, but researchers have been warning that unethical or outright criminal operators are abusing these networks to build and support botnets, cybercrime campaigns, espionage and other malicious activity.

Cordial and Snarky Spider haven’t achieved the impact or technical capability of Scattered Spider, but the groups share many commonalities and objectives, Meyers said. 

“They’ve kind of taken their playbook and they’re using a lot of their techniques, but we haven’t really seen the technical sophistication demonstrated by them that we saw from Scattered Spider,” he said. “It’s kind of the new generation of Scattered Spider.”

Researchers warn that BlackFile, an extortion group likely associated with The Com, continues to impersonate IT support in voice-phishing and social engineering attacks that have impacted organizations in multiple industries, including healthcare, technology, transportation, logistics, wholesale and retail.

Attackers have been actively targeting organizations in the retail and hospitality industry since February, according to Unit 42’s latest intelligence on the campaign, which the Retail & Hospitality Information Sharing and Analysis Center (RH-ISAC) released alongside indicators of compromise Thursday.

The threat group, which is also tracked as CL-CRI-1116, UNC6671 and Cordial Spider, appears to be targeting victims opportunistically in a campaign that remains active and ongoing, Matt Brady, senior principal researcher at Palo Alto Networks’ Unit 42, told CyberScoop. 

“The core objective of these threat actors is to pressure targeted organizations into paying large ransom demands, typically in the seven-figure range,” Brady said.

Unit 42 declined to say how many organizations have been impacted thus far, and RH-ISAC did not respond to a request for comment.

BlackFile’s attacks against companies in the retail and hospitality sector are part of a broader wave of voice-phishing attacks initiated by multiple cybercrime groups, which Google Threat Intelligence Group and Okta warned about in January. 

Unit 42 also noted that BlackFile’s activities overlap with an ongoing data theft and extortion campaign CrowdStrike has been tracking as Cordial Spider since at least October 2025.

Yet, the threat group’s tactics have been far from cordial. RH-ISAC said some attackers have swatted company personnel, including executives, to increase leverage and pressure victims to pay their ransom demands. 

The threat group lures victims via voice-phishing attacks and phishing pages mimicking corporate single-sign on services to steal credentials before moving into privileged accounts. 

“They scrape internal employee directories to obtain contact lists for executives,” RH-ISAC wrote in a blog post. “By compromising these senior accounts via further social engineering, they gain persistent, broad-spectrum access to the environment that mirrors legitimate executive session activity.”

The group’s unauthorized access and data theft for extortion activity spans SaaS environments, Microsoft Graph API permissions, Salesforce API access, internal repositories, SharePoint sites and datasets containing employee’s phone numbers and business records. 

BlackFile also created a data-leak site to extort victims that it claims ignored or failed to agree to its demands, according to researchers. 

Brady said Unit 42 has observed relatively consistent activity from the threat group since February. 

RH-ISAC advises organizations to manage multi-factor identity verification for callers and limit the IT support actions that can be completed in a single call without escalation to management.

A core leader of the hacker subset of The Com responsible for a series of high-profile phishing attacks and cryptocurrency thefts from September 2021 to April 2023 pleaded guilty to federal charges, the Justice Department said Friday. 

Tyler Robert Buchanan of Dundee, Scotland, pleaded guilty to conspiracy to commit wire fraud and aggravated identity theft. The 24-year-old was arrested by Spanish police in Palma in 2024 as he attempted to board a charter flight to Naples, Italy. 

Buchanan has been in federal custody since April 2025 and faces up to 22 years in federal prison at his sentencing, which is scheduled for August 21. 

The British national and his co-conspirators, including Noah Michael Urban, who was sentenced to a 10-year federal prison sentence last year, harvested thousands of credentials via phishing and stole more than $8 million in cryptocurrency from U.S. residents via SIM-swapping attacks.

Victims included high net worth individuals and businesses in the entertainment, telecom, technology, business process outsourcing, IT, cloud and virtual currency sectors, officials said.

Buchanan and his co-conspirators were part of an aggressive subset of The Com coined Scattered Spider. While The Com and its offshoots don’t operate with formal leaders in the traditional sense, Buchanan played a crucial role in the operation, according to Allison Nixon, chief research officer at Unit 221B.

“[Buchanan] was the glue that held this gang together. His success at wiping out victims’ savings made him a target for both law enforcement and rival Com gangs,” Nixon told CyberScoop.

“[Buchanan] is part of an older generation that came from certain toxic gaming servers before the pandemic. People from this generation learned hacking in order to steal vanity usernames and bully kids before using it to steal peoples’ savings,” she added.

Federal authorities filed charges against five individuals with links to the Scattered Spider cybercrime outfit in 2024. Buchanan and Urban’s alleged co-conspirators — Ahmed Hossam Eldin Elbadawy, Evans Onyeaka Osiebo and Joel Martin Evans — still face charges in the case, officials said. 

Nixon lauded law enforcement for acting decisively to arrest Buchanan during a brief window of opportunity while he was traveling internationally. 

“Com members are obsessed with private jets and foreign vacations, and the feds took that dream away with one arrest,” she said. 

The tactic, which U.S. officials also use against Russian cybercriminals, works because most countries are willing to support in the arrest of foreign criminals, thereby keeping them out of their respective jurisdictions, Nixon said. 

“As a foreigner, he was caught in a weaker legal position than if he was arrested at home, and cases following this tactic tend to have very long sentences,” she added. “The takeaway for Com members watching this case is that criminal foreigners associated with violence are the lowest class in every country. And that’s what Com members are when they travel.”

The Justice Department said Buchanan and his co-conspirators defrauded at least a dozen companies and their employees throughout the United States. A digital device police found at his residence in April 2023 contained personal data on numerous individuals and victim companies, according to his plea agreement.

It’s unclear what transpired between that search in April 2023 in Scotland and his June 2024 arrest at a resort city on the Spanish island of Mallorca. Moreover, his plea agreement doesn’t include the entirety of his alleged crimes. 

Buchanan attracted a lot of attention and successfully coordinated many attacks before a rival Com gang allegedly broke into his home and used a blowtorch on him to extract crypto keys in his possession, according to Nixon. 

Following his arrest, Spanish police said Buchanan had gained control of bitcoin worth more than $27 million at that time. 

While early leaders of Scattered Spider have been arrested or sentenced for their crimes, others have filled those roles with even more exceptional impact. 

The Com has grown to thousands of members, typically between 11 and 25 years old, splintered into three primary subsets the FBI describes as Hacker Com, In Real Life Com and Extortion Com.

Criminal acts committed by these multiple, interconnected networks include swatting, extortion and sextortion of minors, production and distribution of child sexual abuse material, violent crime and various other cybercrimes.
