Detects a host making 3 or more outbound connections within 5 minutes to AWS-hosted IP addresses known to host NJRAT C2 infrastructure from the GTA6 lure campaign, consistent with periodic RAT beaconing rather than a one-off incidental connection.
Detects high-frequency requests to the RubyGems legacy API key endpoint, which may indicate attempts to harvest or bruteforce developer API keys. The rule specifically monitors for request patterns involving variations like .yaml, .json, or parameter-based variants often observed in scanning activities.

This rule detects potential Server-Side Request Forgery (SSRF) attempts targeting specific UK council ModernGov websites (e.g., Lambeth, Wandsworth, Southwark). It looks for outbound HTTP requests from non-browser clients (specifically identifying 'Ruby' in the User-Agent string) to these specific gov.uk domains, with a threshold to catch repeated attempts.
Detects network communication associated with Mantax Otax Android malware, including traffic to identified command-and-control (C2) infrastructure and attempts to retrieve dynamic configuration files from GitHub.
This rule detects network traffic directed to the subdomain 'testing.perplexity.com', which is identified as being associated with the BragJack campaign. This specific subdomain is leveraged by the campaign to facilitate browser session redirect bypasses, indicative of an attempt to intercept or manipulate user sessions.

Detects unauthorized or suspicious POST requests to the Cisco Firepower Management Center (FMC) web interface that lack standard authentication headers (Cookie, Authorization, or X-Api-Token). This pattern is consistent with exploit attempts targeting CVE-2026-20079.
Detects SMTP MAIL FROM/Reply-To headers, DNS queries, or TLS SNI matches for known Business Email Compromise (BEC) lookalike domains (e.g., service-nowinc.com, domainlify.net) used for phishing or spoofing organizational identities.

Detects attempts to bypass AWS IMDSv2 security protections via the LiteLLM /config/pass_through_endpoint, where attackers inject the 'x-pass-X-aws-ec2-metadata-token' header to potentially strip authentication requirements.

Detects a multi-stage authentication bypass attempt against LiteLLM MCP endpoints. The rule tracks an initial malformed Authorization Bearer token request to the /mcp/ endpoint, followed by a server response returning a 200 OK status code accompanied by an 'mcp-session-id' header, confirming the exploitation of CVE-2026-59822.
Detects incoming HTTP requests to sensitive LiteLLM endpoints (/mcp and /guardrails) which are typically intended for internal or controlled use. Exposing these to the public internet may allow unauthorized individuals to interact with, enumerate, or exploit the LiteLLM framework's capabilities.
Detects network activity associated with the Mantax/Otax Android malware family, specifically identifying C2 communication to the domain apimantax.otax.fun via TLS SNI and HTTP host headers, as well as potential dynamic C2 configuration retrieval via GitHub using the OkHttp client.
This rule detects outgoing HTTP requests to 'apimantax.otax.fun' attempting to initiate a WebSocket upgrade connection. This is characteristic of the Mantax Otax v2 malware family establishing a Command and Control (C2) channel.
This rule detects command-and-control (C2) communication patterns associated with the 'soraki-proxy.workers.dev' domain, a Cloudflare Workers-hosted proxy service. Additionally, it identifies potential malicious mTLS implants by flagging non-standard TLS handshakes that use self-signed or auto-generated certificates missing standard organization (O) fields in the subject DN.

This rule detects SQL injection attempts targeting the BuddyBoss members REST endpoint, specifically identifying exploitation patterns associated with the 'sqlmap' tool. The rule monitors for specific URL parameters including 'member_type', 'search_terms', and 'scope' in combination with an 'sqlmap' user-agent, indicating an automated exploitation attempt against the application.
This rule detects potential command and control (C2) communication related to the GhostContainer malware. It inspects HTTP POST requests directed at Microsoft Outlook Web Access (OWA) paths containing a suspicious 'x-owa-urlpostdata' header. The presence of this specific header, followed by a base64-encoded string of significant length, indicates an attempt to deliver C2 commands or exfiltrate data through OWA infrastructure.
