LockBit Ransomware Detection

This YARA rule detects LockBit ransomware by identifying specific byte patterns (signatures) within executable files. It contains two main sets of conditions, likely corresponding to different versions or major functional blocks of the ransomware. The first set looks for patterns related to enumerating resources, finding files, and encrypting files. The second set looks for patterns related to checking blacklisted languages (anti-analysis/anti-geofencing), FNV1a hashing, creating network host traversal threads, decrypting configuration, and encrypting files. The rule requires the file to be a Windows executable (MZ header).
