EU Imposes Sanctions on Trickbot Ransomware Leader Vitaly Kovalev

The European Union has imposed sanctions on Vitaly Kovalev, the alleged leader of the Trickbot ransomware operation, also known by the handle "Stern." This action, coordinated with the United States and the United Kingdom, targets a network of cybercriminals and the services that support them.

Kovalev, a 36-year-old Russian national, has been linked to significant ransomware attacks, with Trickbot and its affiliate Conti reportedly responsible for over $180 million in ransom payments in 2021 alone. The group has affected more than 1,000 organizations worldwide, including hospitals and banks, and notably attacked Ireland's Health Service Executive during the COVID-19 pandemic.

The sanctions represent a significant escalation in efforts to combat ransomware. Alongside the EU, the U.S. Treasury's Office of Foreign Assets Control (OFAC) and the UK's Office of Financial Sanctions Implementation had previously sanctioned Kovalev in February 2023, associating him with the aliases "Ben" and "Bentley." In May 2025, Germany's federal police publicly confirmed his identity as the operator behind the "Stern" alias, leading to an Interpol red notice.

Kovalev held a "CEO-like" position in the Trickbot and Conti groups, overseeing their budgets, hiring processes, and attack strategies, as revealed by leaked internal messages. His operation consisted of over 100 members and maintained physical offices, with salaries paid in Bitcoin and a system of employee incentives.

In addition to Trickbot, Kovalev has been implicated in various ransomware strains, including Ryuk and Conti. His wallets have reportedly received more than $300 million from ransom payments. The recent sanctions aim to disrupt such operations and reduce the funding for cybercriminal activities.
