Detects when an attacker modifies values of the Disk Cleanup Handler in the registry to achieve persistence via autorun. The rule specifically looks for modifications to the 'Autorun', 'CleanupString', or 'PreCleanupString' registry values within the 'VolumeCaches' key, combined with specific executable names or common suspicious paths in the 'Details' field.
This rule detects attempts to establish persistence by modifying specific registry keys related to the Windows Event Viewer's redirection functionality. Adversaries can manipulate these keys, specifically 'MicrosoftRedirectionProgram' and 'MicrosoftRedirectionURL', to execute arbitrary programs or open malicious URLs when a user interacts with the Event Viewer. The rule filters out legitimate modifications made by svchost.exe (likely via GPO) for default redirection programs and command-line parameters, as well as the default Microsoft events.asp URL and empty values, to reduce false positives.
Detects a specific UAC bypass technique leveraging Windows Media Player's `osk.exe` by monitoring modifications to a particular registry key. This technique, often associated with UACMe (specifically method 32), involves setting a 'Binary Data' value in the AppCompatFlags\Compatibility Assistant\Store registry path for `C:\Program Files\Windows Media Player\osk.exe`.
Detects the creation of a specific named pipe ('thisispipe') which is known to be used by the DiagTrackEoP Proof-of-Concept tool. This tool exploits the "SeImpersonate" privilege for privilege escalation on Windows systems.
Detects modifications to Windows service paths using the 'sc.exe' utility to point to suspicious executables or common adversary-used paths. This activity can indicate an attempt to establish persistence or escalate privileges by altering how a service executes.
Detects when the 'windir' environment variable is modified from its default value. This modification is often a precursor to a User Account Control (UAC) bypass technique leveraging the 'SilentCleanup' scheduled task, which is an auto-elevated task that can execute with administrator privileges without prompting the user.
Detects a specific UAC bypass technique (UACMe 52) that abuses a path parsing vulnerability in `winsat.exe`. This bypass involves modifying registry keys related to `winsat.exe` to point to a malicious executable located in a temporary directory, allowing for privilege escalation without a UAC prompt.
Detects usage of the "usermod" binary to add users add users to the root or suoders groups
Detects suspicious WMI event filter and command line event consumer based on WMI and Security Logs.
Detects additions to the Emond Launch Daemon that adversaries may use to gain persistence and elevate privileges.
Detects abuse of the cron utility to perform task scheduling for initial or recurring execution of malicious code. Detection will focus on crontab jobs uploaded from the tmp folder.
Detect standard users login that are part of high privileged groups such as the Administrator group
Detects when administrator grants either application permissions (app roles) or highly privileged delegated permissions
Rule to detect the use of the SCX RunAsProvider Invoke_ExecuteShellCommand to execute any UNIX/Linux command using the /bin/sh shell.
SCXcore, started as the Microsoft Operations Manager UNIX/Linux Agent, is now used in a host of products including
Microsoft Operations Manager, Microsoft Azure, and Microsoft Operations Management Suite.

Detects blocked image load events with revoked certificates by code integrity.

Detects the presence of a loaded unsigned kernel module on the system.
Detects the use of Moriya rootkit as described in the securelist's Operation TunnelSnake report
Detects suspicious Powershell code that execute COM Objects
Detects the creation of a schtask via PowerSploit or Empire Default Configuration.
Detects suspicious shell spawn from Java utility keytool process (e.g. adselfservice plus exploitation)
