Detects unauthorized processes (non-browser applications) creating, modifying, or renaming sensitive browser data files such as Login Data, Cookies, or local state files within standard browser profile directories. This activity is indicative of credential harvesting or session hijacking attempts by malicious software.

This activity is indicative of credential harvesting or session hijacking attempts by malicious software.
Detects potential DLL side-loading attempts involving GlobalProtect VPN components. The rule identifies the execution of GlobalProtect.exe with specific command-line arguments combined with the presence of suspicious versions of bcrypt.dll or WININET.dll within the same directory, which are characteristic of recent malicious activity involving modified DLL files targeting GlobalProtect environments.
This rule monitors for a multi-stage attack pattern involving two potential indicators: first, it identifies phishing emails containing a 'Google Docs' link combined with an attachment named 'API Logic Flaw'. Second, it detects browser activity involving the paste of JavaScript code or suspicious browser clipboard activity, which may indicate an attacker attempting to execute malicious scripts directly in the user's browser context.
Detects the installation or modification of a browser extension (manifest.json file creation) followed by network activity from the browser to trusted AI assistant domains within a five-minute window. This behavior is indicative of potentially malicious browser extensions or content scripts being introduced to intercept or manipulate user interaction with AI services.

Detects the suspicious registration of a Cloud Filter provider callback using staging paths and naming conventions associated with the ShieldCrash (CVE-2026-69414) exploit. The rule monitors DeviceEvents for cloud provider activity that originates from unsigned or untrusted binaries, excluding known-legitimate cloud synchronization clients.
Detects indicators of the 'ShieldCrash' proof-of-concept (CVE-2026-69414 exploit bypass) on Windows systems. The rule monitors for specific malicious file activity, module loading, and the presence of decoy archive files associated with the PoC, which are used to achieve arbitrary file read as SYSTEM.
This rule detects modifications to Windows Registry persistence keys (Run and RunOnce) associated with specific suspicious filenames ('cplsupport.exe', 'wtass.exe'), as well as modifications to specific Synapse agent configuration registry keys. These patterns are often associated with persistence mechanisms or unauthorized software configuration changes.
Detects the presence of known file hashes associated with Vectra Remote Access Trojan (RAT). The rule monitors both file creation/existence events and process execution events where the SHA256 hash matches the identified indicators of compromise.
This rule detects potential malicious activity by monitoring for specific file hashes, specific suspicious filenames, and suspicious command-line patterns (e.g., 'antivm') initiated by known update or launcher processes. This is likely an indicator of malware behavior involving anti-sandbox or evasion techniques.
Detects execution or file presence associated with the TraderTraitor malware, specifically targeting known malicious file paths or SHA1 hashes used by the actor to masquerade as legitimate macOS system utilities (iTunesCloud, iSync, AppleAccountd).

Detects host-based activity or network communication associated with the SloppyRAT remote access trojan. The rule monitors for specific malicious file hashes and connection attempts to known C2 IP addresses and domains.
