**LockBit 5.0** is an actively deployed, cross-platform ransomware family targeting Windows, Linux and ESXi/virtualized environments that combines fast XChaCha20/Curve25519 encryption with strong anti-analysis and anti-forensic features; affiliates using a RaaS double-extortion model have exposed at least ~60 victims across sectors, and the variants include virtualization-specific functions to cripple VMs and wipe free space, underscoring a high enterprise impact and persistent criminal infrastructure reuse.
