APT28, the Russian hacking group tied to last year’s interference in the 2016 presidential election, has long been known for its advanced arsenal of tools for penetrating Windows, iOS, Android, and Linux devices. Now, researchers have uncovered an equally sophisticated malware package the group used to compromise Macs.
Like its counterparts for other platforms, the Mac version of Xagent is a modular backdoor that can be customized to meet the objectives of a given intrusion, researchers from antivirus provider Bitdefender reported in a blog post published Tuesday. Capabilities include logging passwords, snapping pictures of screen displays, and stealing iOS backups stored on the compromised Mac.
The discovery builds on the already considerable number of tools attributed to APT28, which other researchers call Sofacy, Sednit, Fancy Bear, and Pawn Storm. According to researchers at CrowdStrike and other security firms, APT28 has been operating since at least 2007 and is closely tied to the Russian government. An analysis Bitdefender published last year determined APT28 members spoke Russian, worked mostly during Russian business hours, and pursued targets located in Ukraine, Spain, Russia, Romania, the US, and Canada.
