Summary: Cisco Talos reported that cyber attacks against Ukrainian government websites, including defacements and destructive wiper malware, have escalated alongside military tensions on the Russian/Ukrainian border. Talos found the WhisperGate malware shares strategic similarities with the 2017 NotPetya wiper, including masquerading as ransomware and destroying the master boot record rather than encrypting it, but has more components designed to inflict additional damage.
Key Takeaway: WhisperGate's multi-stage chain pulls a malicious DLL from a Discord server and drops a second wiper that destroys files, so blocking the listed IOC hashes matters before a machine's boot record is gone.
