Detects a suspicious pattern where an endpoint initiates an HTTP GET request to a known staging IP with a specific 'force=1' parameter, followed by the execution of a bash shell process. This behavior is associated with the ClickFix attack chain used to deliver AMOS Stealer payloads on macOS.
This rule detects outgoing HTTP POST requests to the 'velvet-otter-glagceis.life' domain path '/collect'. The request body contains indicators of victim fingerprinting, specifically looking for 'visitorId' and 'events' fields, characteristic of the Macfinger/ClickFix campaign used for gathering visitor telemetry for malicious purposes.
Detects network activity associated with the AMOS (Atomic macOS Stealer) malware, specifically identifying C2 registration/heartbeat beacons and tasking retrieval requests to known C2 URI paths over port 8133.
Detects network activity associated with the Sauron Loader, including TLS connections to specific C2 domains and repeated HTTPS POST requests to api.* subdomains indicating beaconing or polling behavior.
Detects activity associated with the Sauron Loader malware, specifically monitoring for the execution of rnpkeys.exe or loading of tdwp.dll, followed by a high volume of HTTPS POST requests to the same destination host, which is characteristic of chunked screenshot exfiltration.
Detects network traffic consistent with AMOS Stealer command-and-control (C2) activity, specifically HTTP POST requests to the path '/api/t' on non-standard TCP port 8133. The rule includes a threshold to mitigate noise from single connections.
Detects HTTP POST requests to '/api/credentials' which is indicative of the AMOS (Atomic macOS) Stealer malware exfiltrating stolen credentials. The rule uses a threshold to identify multiple exfiltration attempts from the same source within a short time window.
Detects HTTP POST requests to '/api/credentials' which is indicative of the AMOS (Atomic macOS) Stealer malware exfiltrating stolen credentials. The rule uses a threshold to identify multiple exfiltration attempts from the same source within a short time window.
Detects unauthenticated attempts to exploit CVE-2025-3248 in the Langflow 'validate/code' endpoint, characterized by missing authentication headers and the presence of suspicious Base64-encoded payloads or command execution keywords. Additionally, it identifies potential post-exploitation activity where Langflow processes spawn Python subprocesses.
Detects network activity associated with the AMOS (Atomic Stealer) malware, specifically identifying C2 registration, heartbeats, or credential exfiltration attempts over the non-standard port 8133 using HTTP patterns matching its known API endpoints.
Detects outbound HTTP POST requests characteristic of the Sauron Loader malware, utilizing a specific, randomized URI path structure and a known malicious User-Agent string to establish C2 communication.
Detects outbound HTTP POST requests characteristic of the Sauron Loader malware, utilizing a specific, randomized URI path structure and a known malicious User-Agent string to establish C2 communication.
Detects network communication associated with the Casbaneiro (Metamorfo) banking trojan, specifically identifying DNS queries, TLS SNI headers, HTTP Host headers, and direct IP connections to known malicious C2 infrastructure.
Detects network activity associated with the SloppyRAT malware, specifically identifying C2 authentication attempts via HTTP POST requests containing specific headers and user-agent strings, as well as TLS connections to known malicious domains and IP addresses.
Detects periodic outbound HTTP POST requests consistent with C2 beaconing behavior associated with the Latrodectus malware. The rule identifies multiple POST requests occurring within a 10-minute window, a pattern often used by Latrodectus for command-and-control heartbeats.
Detects network activity associated with the SilkParasite actor's NodeEdgeRAT malware, including DNS queries, TLS SNI, HTTP Host headers, and direct IP connections to the identified command-and-control infrastructure 'hoster-kg.com'.
Detects command-and-control (C2) communication patterns associated with the Graphalgo framework, which utilizes the Arbitrum Sepolia blockchain for dead-drop resolution and task orchestration. The rules monitor for specific JSON-RPC method calls ('eth_call', 'setCPubKey') and repeated polling of contract functions ('serviceData') characteristic of this threat actor's network behavior.
Detects network traffic to GitHub API endpoints that matches patterns indicative of RUSTYSHADE malware communicating with a private repository for command and control. The rule specifically looks for access to repository content paths related to commands, results, heartbeats, screenshots, or information files, coupled with the inclusion of an Authorization token in the HTTP header.
Detects potential JWT algorithm-confusion or authentication-bypass attempts
targeting WSO2 API Manager components through JWTs specifying unsupported,
downgraded, or unexpected signing algorithms such as "none" or HS256 where
asymmetric signing is expected. Matching events should be investigated to
determine whether the request represents exploitation of CVE-2026-5430.

Detects endpoint, process, and network activity associated with the 'TaskStomp' threat actor, specifically targeting known malicious file hashes, command-and-control domains, and specific URLs used in their campaigns.
Detects anomalous HTTP POST requests to a suspected C2 endpoint ('/beacon/pre-register') on a typosquatted domain ('thecovnresation') characterized by an application/octet-stream content type, which is indicative of encrypted C2 beacon registration activity.
