Detects the Blackwood tunneling tool from Blinder Tunnel. Blackwood.dll is sideloaded into a signed vshost32.exe via its .config and reflectively loads Go-compiled Chisel, which dials a raw public IP and opens a reverse SOCKS proxy for lateral pivoting.
Detects outbound SMTP traffic associated withAVERAT malware, tracking the EHLO sequence, STARTTLS command negotiation, server acceptance, and subsequent custom TLS ClientHello patterns on port 25.

This rule monitors for sustained, repeated network connections from specific processes (often legitimate binaries used by the NeedyMantis group for loader activities) to known NeedyMantis-associated C2 domains. It triggers when an initiating process, associated with known loader activity, maintains a persistent communication pattern consistent with an active WebSocket C2 session.
Detects network patterns associated with NeedyMantis-style command-and-control (C2) activity. This includes specific HTTP GET requests with hardcoded User-Agent strings, cookie-based binary data transfer in server responses, and WebSocket communication attempting to establish binary protocol channels.
Detects HTTP beaconing patterns and TLS SNI traffic associated with the Sauron Loader malware. The rules identify specific URI structures (including versioned resources and various configuration/profile endpoints), specific URL parameters used for session management, and characteristic User-Agent strings. Additionally, it monitors for connections to known command-and-control infrastructure via TLS SNI filtering.
This rule detects potential Cobalt Strike SMB beacon activity by identifying the creation of suspicious named pipes (commonly associated with Cobalt Strike) and correlating them with low-jitter, uniform outbound network communication patterns typical of command and control (C2) beaconing behavior.
This rule detects network activity associated with the DarkMe RAT, specifically targeting outbound TCP connections or DNS resolutions involving known C2 domains by the rundll32.exe process. This activity is indicative of the malware's post-injection C2 registration and beaconing.
This rule detects outbound network beaconing from the SCKit malware to known command-and-control (C2) domains hosted on skyleen.fr or to a specific malicious IP address (139.84.223.178). The rule monitors both TLS SNI indicators in HTTPS traffic and direct IP connections to identify compromised hosts communicating with the attacker's infrastructure.
This rule detects potential Cobalt Strike SMB beacon activity by identifying the creation of suspicious named pipes (commonly associated with Cobalt Strike) and correlating them with low-jitter, uniform outbound network communication patterns typical of command and control (C2) beaconing behavior.
Detects network connection attempts to known typosquatted domains (thecovnresation.com/net) commonly associated with the CLEANGULP malware beaconing activity, specifically targeting the /beacon/pre-register URI path.
Detects network connection attempts to known typosquatted domains (thecovnresation.com/net) commonly associated with the CLEANGULP malware beaconing activity, specifically targeting the /beacon/pre-register URI path.
Detects network indicators and session patterns associated with the JWR Phishing Framework, specifically targeting its WebSocket-based command and control (C2) communication, client engine (main.js/ws-worker.js) retrieval, and unique session token (JWRCVV) usage.
Detects network connection attempts to known typosquatted domains (thecovnresation.com/net) commonly associated with the CLEANGULP malware beaconing activity, specifically targeting the /beacon/pre-register URI path.
Detects network activity associated with the NarwhalRAT malware, specifically C2 beaconing via HTTP/DNS to known infrastructure and file downloads from staging domains.
Detects network connection attempts to known typosquatted domains (thecovnresation.com/net) commonly associated with the CLEANGULP malware beaconing activity, specifically targeting the /beacon/pre-register URI path.

Detects Sauron Loader C2 registration/polling: an HTTPS POST whose URI path matches the malware's exact <prefix>/v<1-9>/<action><Resource> structure (action = set|get; resource = one of the 10 known config/task resource names) combined with the malware's hardcoded Windows-10 Edge/Chrome 143 user agent. Narrowing the URI regex from a generic '/api/v1/anything' wildcard to the exact action+resource vocabulary eliminates matches against ordinary versioned REST API traffic, which was the dominant false-positive source.
