Detects the use of 'schtasks.exe' to disable critical Windows Update or ExploitGuard Malware Removal tasks when initiated by 'LockAppHost.exe'. This behavior is highly irregular, as the LockAppHost process is typically associated with the Windows Lock Screen and should not be modifying security-related scheduled tasks.
Detects malicious network connections, file downloads, or process execution associated with the REVSTEALER malware campaign, which utilizes hijacked YouTube channels to distribute fake game-cheat videos that lure users into downloading 'resightloader.exe' from specific malicious domains.

Detects the execution of cmstp.exe with the /au parameter, which is commonly used to install malicious INF files, when initiated by LockAppHost.exe. This pattern is often indicative of an attempt to bypass application control or achieve privilege escalation by leveraging the legitimate Microsoft Connection Manager Profile Installer.

Detects anomalous registry enumeration or modification activities targeting software uninstallation registry keys (Run/Uninstall). By monitoring for multiple subkey accesses by processes not associated with standard software management tools (like MsiExec or explorer), this rule identifies potential reconnaissance or software discovery patterns indicative of malicious activity.

This rule detects the addition of specific suspicious executables to Windows Registry run keys. Adversaries use these keys to achieve persistence, ensuring that malicious programs execute automatically upon user logon.
This rule detects the use of the LockAppHost process to execute suspicious commands associated with tampering with security configurations, including Windows Defender settings, service management (sc.exe), and task scheduling. Adversaries may abuse this process to bypass security controls, disable real-time monitoring, or maintain persistence.
This rule detects network communication associated with the REVSTEALER 'EtherHiding' technique. It monitors for POST requests to Polygon network RPC endpoints containing specific contract interaction signatures ('eth_call' with '0x4965e13f' and a specific contract address), as well as TLS connections to known malicious domains and fallback RPC providers used to resolve C2 instructions from blockchain data.
