Detects incoming Grafana API requests directed at vulnerable mcp-grafana server instances identified by an outdated version (pre-1.1.0). This rule correlates host-level version discovery with application-layer logs containing suspicious 'grafana_api_request' method calls, which may indicate an attempt to exploit Server-Side Request Forgery (SSRF) vulnerabilities.

Detects instances where unauthenticated users or sessions execute privileged 'tools/call' operations within the Grafana MCP dispatcher. This behavior is indicative of potential session spoofing attacks, specifically targeting vulnerabilities similar to CVE-2026-19516, where lack of an Authorization header allows unauthorized access to privileged tool functions.

Detects invocations of the 'grafana_api_request' tool that lack a preceding valid bearer-token authentication event for the same session. This indicates a potential scenario where a server or service account token is being used on behalf of an unauthenticated caller, bypassing normal authentication requirements for the Grafana API.

Detects a PHP TypeError in Magento system logs where array_merge() is called with an integer argument following an include statement. This signature is indicative of exploitation attempts targeting Magento sites using the StyleSmuggler vulnerability, which often involves malicious file inclusion and code execution.

This rule detects the installation of browser extensions that occur during an idle user session (greater than 7 minutes). This behavior is consistent with automated, remote-driven synthetic input injection, often utilized by malware (e.g., NinjaMare) to install malicious extensions without user consent while the system is unattended.

Detects anomalous access to Microsoft 365 services (OneDrive, SharePoint, Mail) where the user activity is characterized by a high volume of operations (more than 30) across a diverse set of objects (more than 15) within a one-hour window. The detection focuses on activity originating from specific common automation/scripting User-Agents (Microsoft Graph, Python httpx/requests) that deviate from typical, focused service account behavior.

This rule detects potential unauthenticated access or unauthorized configuration modifications to an AI agent management backend. It monitors HTTP logs for requests targeting configuration endpoints that lack proper authentication, specifically identifying attempts to retrieve sensitive information like Dify or Coze keys, or attempts to inject new agent configurations via unauthenticated POST requests.

This rule identifies a discrepancy between actual network connections processed by HAProxy and the corresponding entries in its server-side logs. Such inconsistencies can indicate the presence of a malicious backdoor compiled into or injected into the HAProxy process, designed to facilitate C2 traffic while evading standard monitoring by suppressing or omitting logging for those connections.

This rule detects instances where a user account performs a password update without any preceding or associated account verification events (such as email verification, reset requests, or action execution) within a short timeframe. This behavior can be indicative of account compromise where an adversary modifies credentials for a compromised user account.

This rule monitors the Windows Application event log for critical Microsoft SQL Server (MSSQL) events. It detects server crashes, access violations, stack overflows, and high-severity (20+) errors. These events often indicate severe database corruption, underlying system instability, or potential exploitation attempts targeting the database engine.

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.
