Vect 2.0 Ransomware Acts as Wiper, Thanks to Design Error

Check Point and other researchers found that the Vect 2.0 ransomware contains a critical implementation flaw: it generates four nonces per large file chunk but only stores the final nonce, rendering the first three chunks undecryptable and effectively turning the ransomware into a wiper for files >=128 KB across Windows, Linux, and ESXi. The flaw, combined with Vect's active RaaS operation and partnership with TeamPCP (a supply-chain actor), makes it a destructive threat to organizations with critical data; defenders are advised to prioritize prevention, enforce strict access controls, isolate virtualization management, and maintain offline immutable backups.
