Detects potential ClickFix-style social engineering attacks where a victim is prompted to execute an encoded PowerShell command (often via copy-paste into a terminal). The rule specifically monitors PowerShell processes initiated by shell environments (explorer.exe, cmd.exe, or WindowsTerminal.exe) that execute encoded, hidden scripts to perform multiple suspicious network requests for files (e.g., .zip, .enc, .bin) from non-standard domains.

Detects the execution of the 'su' binary preceded by command-line strings that are highly indicative of known Linux privilege escalation exploits, specifically those targeting vulnerabilities like PwnKit (CVE-2021-4034). The rule monitors for common exploit payloads or status messages (e.g., 'prctl PR_SET_DUMPABLE', 'fork userns mapper') associated with successful exploitation attempts that manipulate environment variables or process attributes to elevate privileges to root, while filtering out legitimate container-related processes.
