Cops in Germany Claim They’ve ID’d the Mysterious Trickbot Ransomware Kingpin

Several cybersecurity researchers who have tracked Trickbot extensively tell WIRED they were unaware of the announcement. An anonymous account on the social media platform X recently claimed that Kovalev used the Stern handle and published alleged details about him. WIRED messaged multiple accounts that supposedly belong to Kovalev, according to the X account and a database of hacked and leaked records compiled by District 4 Labs but received no response.

Meanwhile, Kovalev’s name and face may already be surprisingly familiar to those who have been following recent Trickbot revelations. This is because Kovalev was jointly sanctioned by the United States and United Kingdom in early 2023 for his alleged involvement as a senior member in Trickbot. He was also charged in the US at the time with hacking linked to bank fraud allegedly committed in 2010. The US added him to its most wanted list. In all of this activity, though, the US and UK linked Kovalev to the online handles “ben” and “Bentley.” The 2023 sanctions did not mention a connection to the Stern handle. And, in fact, Kovalev’s 2023 indictment was mainly noteworthy because his use of “Bentley” as a handle was determined to be “historic” and distinct from that of another key Trickbot member who also went by “Bentley.”

The Trickbot ransomware group first emerged around 2016, after its members moved from the Dyre malware that was disrupted by Russian authorities. Over the course of its lifespan, the Trickbot group—which used its namesake malware, alongside other ransomware variants such as Ryuk, IcedID, and Diavol—increasingly overlapped in operations and personnel with the Conti gang. In early 2022, Conti published a statement backing Russia’s full-scale invasion of Ukraine, and a cybersecurity researcher who had infiltrated the groups leaked more than 60,000 messages from Trickbot and Conti members, revealing a huge trove of information about their day-to-day operations and structure.

Stern acted like a “CEO” of the Trickbot and Conti groups and ran them like a legitimate company, leaked chat messages analyzed by WIRED and security researchers show.

“Trickbot set the mold for the modern ‘as-a-service’ cybercriminal business model that was adopted by countless groups that followed,” Recorded Future’s Leslie says. “While there were certainly organized groups that preceded Trickbot, Stern oversaw a period of Russian cybercrime that was characterized by a high level of professionalization. This trend continues today, is reproduced worldwide, and is visible in most active groups on the dark web.”

Stern’s eminence within Russian cybercrime has been widely documented. The cryptocurrency tracing firm Chainalysis does not publicly name cybercriminal actors and declined to comment on BKA’s identification, but the company emphasized that the Stern persona alone is one of the all-time most profitable ransomware actors it tracks.

“The investigation revealed that stern generated significant revenues from illegal activities, in particular in connection with ransomware,” the BKA spokesperson tells WIRED.

Stern “surrounds himself with very technical people, many of which he claims to have sometimes decades of experience, and he’s willing to delegate substantial tasks to these experienced people whom he trusts,” says Keith Jarvis, a senior security researcher at cybersecurity firm Sophos’ Counter Threat Unit. “I think he’s always probably lived in that organizational role.”

Increasing evidence in recent years has indicated that Stern has at least some loose connections to Russia’s intelligence apparatus, including its main security agency, the Federal Security Service (FSB). The Stern handle mentioned setting up an office for “government topics” in July 2020, while researchers have seen other members of the Trickbot group say that Stern is likely the “the link between us and the ranks/head of department type at FSB.”

Stern’s consistent presence was a significant contributor to Trickbot and Conti’s effectiveness—as was the entity’s ability to maintain strong operational security and remain hidden.

As Sophos’ Jarvis put it, “I have no thoughts on the attribution as I’ve never heard a compelling story about Stern’s identity from anyone prior to this announcement.”
