Rook Ransomware Detection

This YARA rule detects the Rook ransomware by identifying specific byte patterns associated with its file enumeration, process enumeration, network share enumeration, and file encryption functionalities. The rule looks for distinct sequences of bytes ($find_files, $encrypt_files_p1, $encrypt_files_p2, $encrypt_files_p3, $enum_procs, $enum_shares) that are characteristic of Rook ransomware's operations. The presence of these combined patterns indicates a high probability of Rook ransomware infection.
