Detects evidence of the Rapuncel infostealer attempting to compromise Chrome or Edge browsers. The rule identifies suspicious image loads into browser processes linked to known malicious hashes or the creation of specific browser decryption log files used by the malware to defeat App-Bound encryption.
Detects persistence mechanisms associated with 'ComponentTask33Agent' which involves either creating a scheduled task or modifying Windows Registry Run keys, alongside potential VBScript-based agent execution via wscript.exe.
Detects the use of PowerShell cmdlets (Add-MpPreference or Set-MpPreference) to modify Microsoft Defender exclusions (paths, processes, or extensions). This behavior is often associated with adversaries attempting to evade security detection by excluding malicious files or processes from being scanned by Microsoft Defender.
Detects Node.js or Python processes exhibiting suspicious behavior consistent with information-stealing malware (such as BeaverTail or InvisibleFerret). The rule monitors for these processes accessing sensitive files, including browser credentials, cookies, browser extension wallet settings, cryptocurrency wallet files, and various identification document image types, followed by the execution of archiving utilities (e.g., zip, rar, 7z) to stage the collected data for exfiltration.
Detects the execution of known remote-access or screen-sharing software (e.g., TeamViewer, AnyDesk, RDP) within 30 minutes of launching common video conferencing applications (e.g., Zoom, Teams, Google Meet). This pattern is consistent with an adversary remotely assisting an unauthorized user during a live coding interview or similar assessment process.
Detects a specific behavioral chain associated with the CHOSEN BRICK implant. This rule identifies when a suspected malicious process writes image/screenshot files (.png, .jpg, .bmp) to disk, followed by a network connection to the Telegram Bot API within a 15-minute window, suggesting potential data exfiltration.
Detects a chained sequence of suspicious activity initiated by agentic AI development tools (e.g., Claude Code, Aider, AutoGen). The rule identifies the execution of these tools followed by local reconnaissance commands, lateral movement attempts, and outbound network connections originating from the same host, indicating potential automated exploitation or credential abuse.
Detects anomalous, chained execution patterns initiated by AI agents integrated with Model Context Protocol (MCP) servers. The rule identifies a multi-stage sequence involving the invocation of browser automation tools followed by shell execution and subsequent outbound network activity, potentially indicating an AI-driven attack chaining filesystem, shell, or cloud-API access in an unauthorized manner.
Detects high-volume, individually-tailored spear-phishing campaigns likely assisted by Generative AI. The rule monitors for a single sender targeting a high number of unique recipients with distinct, non-identical email subjects within a short timeframe. It specifically flags activity involving newly registered look-alike domains and interactions with credential-harvesting patterns in URLs.
Detects outbound HTTPS connections to major generative AI inference endpoints originating from non-browser, non-development tool processes at regular intervals. This activity is indicative of beaconing behavior, where malware (specifically families like LAMEHUG) leverages LLM APIs for dynamic command generation, payload obfuscation, or C2 instruction retrieval, bypassing traditional security controls.
