VECT 2.0 is a cross-platform (Windows, Linux, ESXi) Ransomware-as-a-Service that effectively functions as a wiper due to a critical cryptographic implementation flaw. Files larger than 128 KB are encrypted in chunks using raw ChaCha20-IETF, but the malware fails to save the required nonces for the first three chunks, rendering full data recovery impossible even if the ransom is paid.
