This rule monitors for web server exploit attempts (indicated by patterns like JNDI lookups or SQL injection sequences in URI/cookie data) that correlate with a surge in server-side errors (400+ status codes) and subsequent anomalous process creation or outbound network connections from the web server process.

Detects the creation of a WordPress administrator account within one hour of a recorded web request to a known web shell path (Mushr00w) or suspect plugin upload directory. This correlation is a high-fidelity indicator of post-exploitation persistence and administrative account hijacking.

This rule monitors the software inventory for outdated versions of the PostgreSQL database server. It identifies installations where the major and minor versions are below the threshold for current security releases (e.g., v18 < 6, v17 < 11, v16 < 15, v15 < 19, v14 < 24). Running outdated software increases the risk of exploitation of known vulnerabilities.

Detects instances where common web server processes (e.g., PHP, Apache, Nginx) spawn child processes associated with command-line utilities (e.g., curl, bash, python). The rule specifically monitors for command-line arguments referencing log files or traces, which is indicative of potential exploitation attempts or post-exploitation activities such as log poisoning or remote code execution.

This rule detects anomalous high-frequency, short-duration bursts of CAPWAP (Control and Provisioning of Wireless Access Points) traffic originating from external sources and targeting internal FortiGate devices. This behavior is indicative of automated exploitation attempts, specifically targeting known heap-grooming activities used in vulnerabilities like CVE-2023-27997, which rely on repetitive 'Add-Station' operations. Legitimate controller traffic is filtered by focusing on internal-to-internal communication patterns.

Detects anomalous serialized object payloads within authenticated GraphQL subscription requests to GitLab Duo Chat endpoints. This pattern is indicative of exploitation attempts targeting the insecure deserialization vulnerability in GitLab EE (CVE-2026-87719), where malicious payloads are injected into serialized data streams.

Detects the initialization of containerized LLM-based gateway services (e.g., litellm, ollama) followed closely in time by high-volume network traffic containing suspicious web injection payloads (e.g., SQLi, XSS, SSRF). The rule correlates process execution events for container launches with network activity originating from the same device to identify potential unauthorized or unsupervised automated exploitation.

This rule detects potential exploitation attempts (CVE-2026-59822) against LiteLLM MCP tool endpoints. It identifies HTTP requests where the authorization bearer token is unusually short (<= 12 chars), lacks the 'sk-' prefix, and does not appear to be a valid JWT, yet successfully results in a 200 OK status, indicating a potential bypass of authentication logic.

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 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 requests to a LiteLLM proxy that have been assigned the 'PROXY_ADMIN' role despite the absence of valid authentication credentials (Authorization headers, JWT tokens, or OAuth2 tokens). This pattern typically indicates that the LiteLLM instance is misconfigured, specifically that a 'master_key' is missing, causing the proxy to default to a permissive mode where every request is treated as having administrative privileges.

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 the creation or update of LiteLLM custom code guardrails that include suspicious Python snippets, specifically 'import os' and 'os.popen', which are indicative of attempts to execute arbitrary OS commands via guardrail logic (CVE-2026-59821).
