Summary

Hide ▲

The VECT 2.0 malware now behaves like a wiper rather than recoverable ransomware, permanently destroying large files and raising the stakes for victims. The destructive flaw affects Windows, Linux, and ESXi variants, and files over 131,072 bytes become unrecoverable even if ransom is paid. The Windows build adds anti-analysis, safe-mode persistence, and lateral spread features, while the ESXi build uses geofencing and anti-debugging checks.

    VECT 2.0 analysis shows large-file destruction across Windows, Linux, and ESXi

    Technical Analysis Update

    Check Point Research says VECT 2.0 functions like a wiper rather than recoverable ransomware across Windows, Linux, and ESXi because files larger than 131,072 bytes lose the nonce material needed for decryption, making ransom payment ineffective. The operation's affiliate program first launched in December 2025, and its current data leak site lists only two victims said to have been compromised through TeamPCP supply-chain attacks.
