Satana Ransomware Detection (YARA)

This YARA rule detects the Satana ransomware by identifying specific byte patterns associated with its file encryption routines, file searching mechanisms, and remote connection capabilities. The rule looks for distinct sequences of bytes ($encrypt_files_p1, $encrypt_files_p2) indicative of how the ransomware encrypts files, patterns related to how it searches for files ($search_files_p1, $search_files_p2), and byte sequences involved in establishing remote connections ($remote_connection). The rule requires the presence of the remote connection patterns, along with all file searching and file encryption patterns, to trigger a detection, ensuring a high confidence in identifying Satana ransomware.
