Detects the initial execution of FakeUpdates/SocGholish malware. This rule identifies scenarios where 'wscript.exe' is used as a parent process to execute a JavaScript file from the 'AppData\Local\Temp' directory, often containing 'update' and '.zip' in its command line, and subsequently spawns 'cmd.exe' or 'powershell.exe'. The presence of browser names in the parent command line further indicates a drive-by download infection vector.

This YARA rule detects the ChaosRAT backdoor by identifying specific byte sequences related to its network communication, system information gathering, and file download capabilities. The rule includes three distinct versions of these functionalities, indicating evolution or different variants of the malware. Detection relies on the presence of these unique byte patterns within executable files, specifically ELF files as indicated by the magic byte check.

This rule detects modifications to specific Windows Registry keys that are known to be used by BlackByte ransomware for privilege escalation and to prepare for lateral movement and encryption. Specifically, it looks for the setting of 'LocalAccountTokenFilterPolicy', 'EnableLinkedConnections', and 'LongPathsEnabled' to a DWORD value of '1'. These modifications can enable administrative shares for non-administrator accounts, allow for longer file paths, and potentially facilitate ransomware operations.
