The Russian state-sponsored APT known as Star Blizzard has transitioned to using a new backdoor, MaybeRobot, following the public disclosure of its LostKeys malware. This change comes as the group continues to employ sophisticated infection techniques to target civil society members in Russia.

The Bitter APT group is leveraging an old vulnerability in WinRAR to deploy new backdoor attacks. This highlights the ongoing threat posed by advanced persistent threats (APTs) that exploit outdated software vulnerabilities.
