Mint Sandstorm - AsperaFaspex Suspicious Process Execution
Detects suspicious process execution patterns originating from AsperaFaspex, specifically targeting activities observed in campaigns attributed to Mint Sandstorm. The rule looks for PowerShell execution with suspicious command-line arguments (e.g., for credential dumping, defense evasion, or discovery), execution of tools like wget or curl for downloading content, attempts to modify local administrator groups, registry modifications for defense evasion, and WMI/vssadmin/wbadmin commands for persistence or defense evasion. This behavior indicates potential post-exploitation activity.
