A federal judge in Connecticut today handed down a sentence of time served to spam kingpin Peter “Severa” Levashov, a prolific purveyor of malicious and junk email, and the creator of malware strains that infected millions of Microsoft computers globally. Levashov has been in federal custody since his extradition to the United States and guilty plea in 2018, and was facing up to 12 more years in prison. Instead, he will go free under three years of supervised release and a possible fine.
Authorities in Spain have arrested a Russian computer programmer thought to be one of the world’s most notorious spam kingpins.
Spanish police arrested Pyotr Levashov under an international warrant executed in the city of Barcelona, according to Reuters. Russian state-run television station RT (formerly Russia Today) reported that Levashov was arrested while vacationing in Spain with his family.
According to numerous stories here at KrebsOnSecurity, Levashov was better known as “Severa,” the hacker moniker used by a pivotal figure in many popular Russian-language cybercrime forums. Severa was the moderator for the spam subsection of multiple online communities, and in this role served as the virtual linchpin connecting virus writers with huge spam networks that Severa allegedly created and sold himself.
Over the past 18 months, I’ve published a series of posts that provide clues about the possible real-life identities of the men responsible for building some of the largest and most disruptive spam botnets on the planet. I’ve since done a bit more digging into the backgrounds of the individuals thought to be responsible for the Rustock and Waledac spam botnets, which has produced some additional fascinating and corroborating details about these two characters.
Microsoft on Monday named a Russian man as allegedly the guy responsible for running the Kelihos botnet, a spam engine that infected an estimated 40,000 PCs. But closely held data seized from the world’s largest spam affiliate program suggests that the driving force behind Kelihos is a different individual who is still coordinating spam campaigns for hire.
Kelihos shares a great deal of code with the infamous Waledac botnet, a far more pervasive threat that infected hundreds of thousands of computers and pumped out tens of billions of junk emails promoting shady online pharmacies. Despite the broad base of shared code between the two malware families, Microsoft classifies them as fundamentally different threats. The company used clever legal techniques to seize control over and shutter both botnets, sucker punching Waledac in early 2010 and taking out Kelihos last fall.
On Monday, Microsoft filed papers with a Virginia court stating that Kelihos was run by Andrey N. Sabelnikov, a St. Petersburg man who once worked at Russian antivirus and security firm Agnitum. But according to the researcher who shared that intelligence with Microsoft — and confidentially with Krebs On Security weeks prior to Microsoft’s announcement — Sabelnikov is likely only a developer of Kelihos. Rather, the researcher argues, the true coordinator of both Kelihos and Waledac is another Russian man who is well known to anti-spam activists.
