Microsoft, along with a group of industry partners, disrupted EvilTokens, a short-lived but highly consequential cybercrime platform that investigators linked to more than 12,000 compromised Microsoft customer email inboxes across more than 10,000 organizations globally, the company said Tuesday.

Acting on federal court order Sept. 15, Microsoft and partners seized 50 websites the phishing-as-a-service used for operations and disabled more than 175 domains linked to EvilTokens’ supporting infrastructure. 

EvilTokens, launched in February 2026, was “a powerful cybercrime platform that used AI at every step of the attack chain — from compromising email accounts to designing intricate roadmaps for financial fraud and scams,” Steven Masada, associate general counsel and general manager of Microsoft’s Digital Crimes Unit, wrote in a blog post.

About 1,000 cybercriminals used EvilTokens over the course of its operation, a Microsoft spokesperson told CyberScoop.

The service was centered on an AI-style chatbot that cybercriminals used to analyze victims’ inboxes, identify trusted relationships, payment authorizations and other sensitive details that could facilitate fraud.

“AI was not simply helping attackers write more convincing messages. It helped them decide who to target, who to impersonate, and how to most effectively exploit the relationship to extract as much money as possible,” Masada wrote. 

EvilTokens was one of the most widely used phishing-as-a-service platforms prior to its takedown. It facilitated business-email compromise campaigns by stealing session tokens that allowed cybercriminals to sift through a victim’s inbox and maintain persistent access.

“We cannot estimate the total fraud attributable to all EvilTokens activity. However, we were able to correlate at least 13 complaints filed with the FBI’s Internet Crime Complaint Center to EvilTokens-linked activity, representing approximately $1.7 million in reported losses,” a Microsoft spokesperson said. “Because many incidents go unreported and not all victims can be definitively linked to specific campaigns, we believe this is a conservative estimate.”

Victims of EvilTokens were largely concentrated in the United States, Canada, the United Kingdom, Australia, India and France, according to Microsoft. SpyCloud, which supported the takedown, identified compromised email domains spanning 79 countries.

Microsoft said it also identified two men behind EvilTokens — Felix Utomi and Waidi Segun Adams — and attributes the development and support of the platform to Storm-2992, a threat actor unaffiliated with any other known cybercrime groups.

The United Kingdom’s Metropolitan Police acted on that information Sept. 18 when it served warrants in the greater London area, arrested the men accused of making articles for use in fraud and money laundering and seized their digital devices.

The Metropolitan Police said it received information from Microsoft about EvilTokens’ administrators in August. Utomi and Adams were released on bail as the investigation continues. 

“The two primary operators identified in our investigation were residing in the U.K.,” a spokesperson for Microsoft told CyberScoop. “While our investigation focused on those individuals, we believe others may have supported the operation in various capacities.”

Microsoft’s legal filing in the U.S. District Court for the Eastern District of Virginia refers to five additional unidentified people allegedly acting as support personnel and users.

Microsoft and others involved in the EvilTokens takedown, including Health-ISAC, Cloudflare, OpenAI, Shadowserver and TRM Labs, didn’t fully quantify how much fraud the service enabled, but it gained popularity quickly among cybercriminals and was lucrative for its operators.

Coinbase, which also aided the investigation into EvilTokens, said it traced about $1.1 million in revenue for EvilTokens from its paying customers. The virtual currency company’s threat researchers found more than 1,000 deposits to EvilTokens from more than 700 distinct addresses through June 2026. 

Operators sold access to the service through Telegram for a $1,500 initiation fee and a recurring $500 subscription. EvilTokens significantly lowered the barrier to entry for cybercriminals by including specialized tools for identity attacks, cloud systems, social engineering and financial fraud in a single interface.

The service allowed cybercriminals to map organizational structure and permissions in Microsoft Graph, which enabled lateral movement, researchers said. With active tokens gained through a collection of highly-targeted phishing lures, cybercriminals consistently bypassed multi-factor authentication, email gateways and endpoint security tools.

Microsoft said the platform’s creators developed portions of the platform with AI and it uncovered capabilities from multiple AI models. 

“It packaged much of the criminal process into a commercially run service, complete with subscription pricing, customer support, management dashboards and tools designed to move customers from account access toward financial exploitation,” Masada added.

The companies and organizations involved in the globally-coordinated takedown identified and notified potential victims, shared indicators of compromise and shared intelligence with law enforcement about EvilToken’s operators and some of its customers.

Experts advised organizations and employees to treat unsolicited device codes as a red flag, assume compromised accounts are fully cataloged in minutes, and independently verify requests to change payment information or redirect funds.

“The infrastructure supporting EvilTokens has been disrupted, but the model it demonstrated will not disappear with it,” Masada warned.

The Trump administration rolled out a six-month test program in Texas on Monday that will draw on volunteer expertise and technology from cyber and artificial intelligence companies to protect the water sector.

“Project Watershed 250” is the first of the state-based, industry-centric pilot projects to cross the finish line that the Office of the National Cyber Director has previewed since the publication of its national cybersecurity strategy earlier this year. Water systems have long been viewed as among the most vulnerable and neediest critical infrastructure sectors, and in recent months the sector has been the victim of a spree of attacks.

“Project Watershed 250 is a commitment from the states, industry and federal government that we will continue to prioritize our nation’s safety and deliver on America-first policies for the American people,” National Cyber Director Sean Cairncross said at a rollout event in San Antonio Monday.

“U.S. companies are providing world-class cyber capabilities, red teaming that tests utilities’ current defenses, system hardening using the latest private sector cyber tools and AI tooling that helps utilities’ frontier cyber defenders to protect Texas water systems and scale proven solutions across the country,” he said. “This six-month pilot program is designed to make our water and wastewater critical infrastructure more resilient and resistant to cyber attacks by proactively finding and fixing system weaknesses.”

The pilot program, featuring collaboration between federal and state governments, stands in contrast to how the Biden administration tried to tackle the issue, with audit requirements that some GOP states challenged in court, forcing Biden’s Environmental Protection Agency to withdraw its rule.

“For too long, at least on the federal level, the government has admired the problem of cybersecurity in water systems,” Cairncross said. “We are going to find out what works. We’re going to target that, and we are going to scale off of this and learn lessons.”

A dozen companies — Parsons, Microsoft, Fortinet, Google Cloud, Palo Alto Networks, Amazon Web Services, Reflection AI, Cloudflare, Zscaler, Forescout, Abnormal AI and Dragos — appeared at the rollout Monday to praise the initiative and tout their contributions to it.

Not everyone praised the initiative elsewhere, however. One cyber professional who works on water security issues, speaking on condition of anonymity, said the program was “all smoke” and that “there’s no real money behind it.”

“The White House did what it always does — reached out to industry with their hands out asking for industry to pay for things the government should be doing, at least in part,” the person said.

Texas Gov. Greg Abbott said the program would be overseen by Cairncross’s office and Texas Cyber Command, which was established just last year. Abbott cited the need for the program by mentioning “an Iranian-backed cyberattack” on 30 water systems across 12 states and a 2024 attack on the water system in Muleshoe, Texas, suspected to be the work of Russian hackers.

“The need for cyber resilience is overwhelming,” Abbott said. “Many rural providers simply don’t have the resources they need to be able to protect themselves.”

Watershed 250 isn’t the only federal effort to bolster water cybersecurity, with lawmakers introducing legislation in the aftermath of the recent attacks. Past legislation that Congress has enacted also sought to tackle the problem.
