A U.S. judge sentenced a Russian man who built a reputation as a global spam kingpin to time served in prison, over the wishes of prosecutors who hoped the defendant would spend more than a decade behind bars. Peter Levashov, known by the online alias “Severa,” who was arrested in Spain in 2017, faced up to 12 more years in prison after he pleaded guilty to operating one of the largest botnets ever.

Security vendor MalwareBytes highlighted the malware spam campaign Tuesday, describing how unidentified attackers send “malspam” messages with both a URL and a file that purports to be a Microsoft update of the Kaseya VSA vulnerability. Clicking on the the link, or “SecurityUpdates.exe,” drops Cobalt Strike on a victim. Cybercriminals have increasingly leveraged that security testing tool for attacks, according to recent research. It’s another example of how cyberattacks can have long tails after their initial infections. The zero-day vulnerability that the ransomware gang REvil apparently used to infiltrate Kaseya systems turned into a way for intruders to access the systems of Kaseya’s managed service provider customers, who provide IT services to a wider range of potential victims. It has turned […]
