Trend Research analyzed the latest version of LockBit ransomware, LockBit 5.0, which exhibits advanced obfuscation, anti-analysis techniques, and cross-platform capabilities for Windows, Linux, and ESXi systems. The Windows variant uses heavy obfuscation and packing, loading its payload through DLL reflection and implementing anti-analysis techniques. The Linux variant has similar functionality with command-line options for targeting specific directories and file types. The ESXi variant specifically targets VMware virtualization infrastructure. All variants use randomized 16-character file extensions, have Russian language system avoidance, and clear event logs post-encryption. The existence of multiple variants confirms LockBit's continued cross-platform strategy, enabling simultaneous attacks across entire enterprise networks including virtualized environments.
