Out of date: the sync last ran 3 hours ago. Newer CVEs and scores may be missing from the map.
The strips, in order: the CVEs it is reported to exploit by weakness class and by vendor, the techniques ATT&CK says it uses by tactic, its malware and tools, then who it targets. Each square is one record.
MSTIC has not found any notable associations between this observed activity, tracked as DEV-0586, and other known activity groups. MSTIC assesses that the malware (WhisperGate), which is designed to look like ransomware but lacking a ransom recovery mechanism, is intended to be destructive and designed to render targeted devices inoperable rather than to obtain a ransom.
