20,501 detections

Detects post-exploitation shell activity spawned from the IIS worker process (w3wp.exe), narrowed to command lines carrying encoded/obfuscated PowerShell flags, remote-download cradles, or basic recon/persistence commands (whoami, certutil, bitsadmin, schtasks, reg add). This reduces noise from benign w3wp.exe-initiated automation while retaining the behavioral pattern seen in the Telerik UI for ASP.NET AJAX unauthenticated RCE chain (webshell/in-memory DLL execution dropping to a shell).

This rule detects potential unauthorized use of MeshAgent RMM software by correlating process execution events (mvtcs.exe, MeshAgent) with network traffic to specific IP addresses identified as associated with Settra command-and-control infrastructure. It specifically filters for MeshAgent activity and validates the threat by requiring an established network connection to known malicious endpoints.

Detects the execution of npm commands to install specific, potentially malicious or typo-squatted npm packages. The rule filters for common npm install command line arguments and matches against a predefined list of package names that are often associated with supply chain compromise attempts.

002
This rule detects instances where a Node.js process spawns a child Node.js process from a 'node_modules' directory using configuration flags typically associated with hidden, detached background tasks (e.g., 'detached', 'stdio', 'windowsHide', 'ignore'). It explicitly excludes common Node.js process managers and build tools to reduce false positives associated with legitimate development activities.

Detects indicators associated with the exploitation of CVE-2025-3248 in Langflow. The rule identifies anomalous web requests targeting the /api/v1/validate/code endpoint, subsequent suspicious process creation (base64 encoded payloads in Python/shell), and network communication with identified command and control (C2) or data exfiltration IP addresses. It also includes alerts for observed contact with known extortion email addresses.

This rule detects the use of specific tools associated with credential dumping and memory forensics, including Dokan driver installations for file system mounting, the use of DumpIt for creating memory dumps, and the subsequent analysis of these dumps using MemProcFS to access sensitive process memory information such as LSASS minidumps.

Detects potential C2 activity associated with MQTTDoor or MatrixDoor malware by monitoring suspicious network traffic patterns. This includes unauthorized processes connecting to MQTT brokers (hivemq.com), non-chat applications interacting with a Matrix homeserver, and geo-location lookups (ip-api.com) occurring shortly after process execution.

Detects git checkout of a bare 40-hex commit SHA or the literal FETCH_HEAD ref, executed by a recognized AI coding-agent process. Narrowed to the Plugin4Shell exploitation fingerprint (checkout of a pinned-SHA-shaped or FETCH_HEAD ref) rather than ordinary branch/tag checkouts, which these agents perform constantly during normal plugin installs.

Detects the Sauron Loader DLL side-loading chain: rnpkeys.exe (legitimate) side-loading malicious rnp.dll, which loads tdwp.dll to decrypt the loader in memory, all staged from C:\ProgramData\keyroll. Requires BOTH DLLs to be loaded by the same rnpkeys.exe process instance (not either/or) to eliminate single-artifact false positives, and surfaces SHA256 hashes of all three components for direct comparison against known IOCs (legitimate rnpkeys.exe: 194d7e8870ff783ce1e4e4e3015c895cc67ae52fd5e063c89dd1c069400d3991; malicious rnp.dll: 5606afdc5191d42f38d3c4f1692eda0a629c88810e29bfe78528733284ad1bf8; malicious tdwp.dll: 6551293e996d19755ba497f50b30a18c178f0d6e2a73b29ae742b8171e2985b7).

Detects creation of the 'keyroll' scheduled task used to relaunch the Sauron Loader DLL side-loading chain. Requires the schtasks.exe command line to both reference the 'keyroll' task name AND explicitly reference the ProgramData\keyroll path or rnpkeys.exe (ruling out unrelated tasks that happen to be named 'keyroll', e.g. legitimate key-rotation automation), and requires an INNER join corroborating an actual rnpkeys.exe relaunch from that path within 24h — a lone task-creation event with no follow-on relaunch no longer alerts.

Detects exploitation attempts by the CARBONATO botnet targeting exposed Docker daemons. The rule monitors for container escape techniques using 'nsenter' to access host namespaces, the execution of specific malicious entrypoint scripts, the use of known malicious container image references, and the creation of privileged containers with host bind mounts, which are indicative of host filesystem and network compromise.

Detects activity associated with the CARBONATO botnet, specifically the weaponization of the Hermes Agent framework. The detection monitors for the overwrite of the SOUL.md configuration file to inject a malicious GH0ST persona, execution of the hermes-agent binary from known malicious paths, and the presence of the CARBONATO_API_KEY environment variable or command-line parameter.
