A new wiper attack has been identified affecting Ukraine. (self.blueteamsec)

"A new wiper attack has been identified by ClearSky Cyber Security affecting Ukraine. We named this wiper "GamaWiper" (VBS-based wiper). The intrusion chain begins with the exploitation of a vulnerable WinRAR version (CVE-2025-80880). We assess with moderate confidence that this activity is linked to the Gamaredon APT group. This marks the first observed instance of Gamaredon conducting destructive operations rather than its traditional espionage activities."
