Detects unexpected crashes of major security software agents (e.g., Antivirus, EDR) that are not associated with authorized vendor update or installation activities, potentially indicating tampering or exploitation attempts to disable security controls.
Detects execution or file presence associated with HOOKEDGE/HEADLACE malware. This rule uses a dual-approach: matching known malicious file hashes (SHA256) and monitoring for specific script files (bat, vbs, cmd) following a GUID-formatted naming convention typically used by the HOOKEDGE installer chain.
This rule detects attempts to modify file or directory permissions (e.g., using icacls, takeown, chmod, or chown) on paths associated with known security products. Such activity is often indicative of an adversary attempting to tamper with, disable, or exclude security tools from logging or inspection.
Detects unauthorized access to sensitive browser credential files (e.g., Chrome 'Login Data', Firefox 'logins.json' and 'key4.db') by processes other than legitimate browser executables. This behavior is indicative of credential harvesting attacks, such as those performed by BabylonRAT.
This rule detects attempts to modify file or directory permissions (e.g., using icacls, takeown, chmod, or chown) on paths associated with known security products. Such activity is often indicative of an adversary attempting to tamper with, disable, or exclude security tools from logging or inspection.

Detects command line containing reference to the "::$index_allocation" stream, which can be used as a technique to prevent access to folders or files from tooling such as "explorer.exe" or "powershell.exe"
Cortex Agent Exception Rule Created
Cortex XDR
Detects the creation of a new exception rule within the Cortex endpoint agent management configuration. Exception rules can be used to exclude specific files, processes, or behaviors from security prevention policies, potentially leading to a reduction in defensive coverage.
This rule detects attempts to disable, stop, or uninstall various security products, including antivirus and EDR solutions, by monitoring command-line activity for administrative utilities like sc.exe, net.exe, wmic.exe, and PowerShell.

Detects the SourTrade browser-side build-pipeline setup sequence: a ServiceWorker registered at /sw.js immediately followed, within the same page load, by a SharedWorker instantiated from an in-page Blob URL carrying an application/javascript MIME type — restricted to domains flagged as newly-registered or low-reputation — consistent with the pre-download preparation stage of browser-assembled malware.
Detects files containing 3+ TOKYOCORE ransom note strings combined with 2+ C2-related strings (Tier 2 cluster overlap)
