Detects when the Microsoft Management Console (MMC) loads scripting engine DLLs such as vbscript.dll, jscript.dll, or jscript9.dll. This activity can indicate an attempt to execute malicious scripts within a trusted system process, potentially for bypassing application whitelisting or defense evasion.

Detects the use of PowerShell cmdlets (`Get-LocalGroup`, `Get-LocalGroupMember`) or WMI queries (`Get-WmiObject`, `Get-CimInstance` targeting `Win32_Group`) to gather local group information. Adversaries commonly use these methods to discover local system permission groups and identify users with elevated privileges, such as local administrators.

Detects the execution of CoercedPotato, a tool used for privilege escalation. The rule specifically looks for the executable name 'CoercedPotato.exe', the command-line argument '--exploitId', or specific import hashes (IMPHASH) associated with the tool. This tool leverages vulnerabilities to achieve higher privileges on a system.

Detects suspicious calls to the "ShellExec_RunDLL" exported function of SHELL32.DLL using an ordinal number to launch other commands. Adversaries might use ordinal numbers to bypass detections that rely on the function name in the command line. The rule looks for specific ordinal numbers associated with ShellExec_RunDLL and combines this with suspicious parent command-line arguments (e.g., containing 'comspec', 'iex', 'Invoke-', or paths like 'Temp') or suspicious child processes (e.g., bash, cmd, powershell, bitsadmin, msiexec).
