Detects processes that make outbound API calls to known Large Language Model (LLM) domains while simultaneously performing high-volume network connection attempts or scanning-like fan-out activity across multiple public IP addresses.
Detects the creation of cook.pth or cook.py in Python site-packages or dist-packages directories by package managers or interpreters, followed by a Python interpreter execution on the same device within one hour. This pattern matches the malicious supply chain behavior observed in compromised LiteLLM versions (e.g., 1.107.0) utilizing .pth auto-import chains for persistence and execution.
Detects process injection activities (such as remote thread creation, memory allocation, and writing to virtual memory) targeting common Windows background processes where the injecting process runs directly from the C:\Windows\ directory with a random or suspicious executable name.
Detects attempts to disable or tamper with Windows Defender settings, services, or registry keys via command-line execution (such as reg.exe, PowerShell, or sc.exe) or direct registry modifications.
Detects post-exploitation behavior where a PaperCut server Java process spawns local account creation or administrator reset followed closely by Active Directory enumeration on the same host, indicating potential post-RCE meterpreter activity.
Detects PowerShell execution spawning 7zr.exe to extract password-protected 7z archives using overwrite and password switches within a specified timeframe, or referencing specific malicious IOC file names and domains.
Detects the correlation of Registry Run key values for known utilities (Lightshot, Procmon, RuntimeBroker) pointing to paths in Program Files with a scheduled task creation of the same name on the same device within a 1-hour window.
Detects a single non-browser process accessing the 'Web Data' files of multiple different web browser families within a short timeframe, which is indicative of credential harvesting or browser stealer activity.
Detects a sequence where PowerShell downloads an .msi installer file from Azure Blob Storage, followed closely by msiexec.exe spawning a PowerShell process on the same device.
Detects the installation or service setup of unauthorized remote access tools (such as AnyDesk, TeamViewer, or ScreenConnect) followed by outbound public network connections from the same device within a one-hour window.
Detects the correlation of two or more distinct discovery tools or artifacts (such as SharpShares, NetScan, NetExec, ShareFinder, and specific nltest.exe domain trust commands) executed on the same device within a one-hour window.
Detects outbound network connections from Python processes associated with known indicators of compromise or specific suspicious command line arguments such as cook.py, cook.pth, or privcollect.
Detects Microsoft Edge (msedge.exe) spawned by command shells or script hosts with hidden or headless window parameters, or communicating with webhook.site, which is commonly indicative of malicious browser automation or exfiltration.
Detects network connections to the npm registry (registry.npmjs.org) initiated by AI coding agent processes (such as Claude, Cursor, Copilot, Windsurf, Codeium, Aider) or by unexpected processes that are not standard package managers or browsers.
Detects execution of a Python script named SysMon.py via a scheduled task, correlated with a subsequent network connection to ipinfo.io initiated by the same Python interpreter within a 10-minute window.
Detects the execution of the AI prompt hook script 'project_context_hook.py' or the creation/modification of the associated investigation state files (scope.md, surface.md, notes.md) within the same folder.
Detects endpoint network connections and correlates multi-stage communications associated with the ClickFix browser cache smuggling campaign, including initial payload retrieval and secondary stage/C2 communication across devices.
Detects the presence of Tailscale binaries (tailscale.exe, tailscaled.exe) on a device within 24 hours of other campaign-specific toolkit components such as kitanai.exe, nandemo.exe, ufw.exe, or upd-ms.bat, indicating potential unauthorized remote access setup.
Detects potential C2 beaconing activity associated with Potassium by correlating a DNS query for a known C2 domain with a subsequent TCP connection to port 50792 from the same device within a short time window.
Detects the Tensorlake npm 0.5.144 compromise (Shai-Hulud worm via preinstall). Includes a baseline query to identify the affected package/version across Defender inventory, file, network, device and process events, plus preinstall download/obfuscated-exec behaviour. Results are summarized per device/account.
Detects the execution of fsquirt.exe spawned by INISAFECrossWebEXSvc.exe where fsquirt.exe subsequently loads an unsigned or untrusted DLL, indicative of a potential TechHub DLL side-loading technique.
