Detects high-frequency password reset or credential recovery attempts originating from a single source IP against multiple user accounts. This behavior is indicative of an automated enumeration or brute-force attack, potentially exploiting vulnerabilities such as the referenced CVE-2026-18963.
Flags an MCP request when its routing label and the instructions inside do not match. For example, the label points to Task A, but the request inside asks for Task B. This could be an attack attempt or a software mistake; the alert alone does not mean unauthorized access succeeded.
Detects potential exploitation of CVE-2025-3248 in Langflow by identifying suspicious inbound network traffic targeting the /api/v1/validate/code endpoint, correlated with subsequent python child processes containing base64 decoding and execution primitives such as eval, exec, or subprocess.

Detects successful user authentication events originating from an external source IP address. This rule is intended to identify remote logins that can be correlated with RMM (Remote Monitoring and Management) activity or other remote access patterns.
This rule detects potential exploitation activities targeting Atlassian Confluence by monitoring for unauthorized access to administrative configuration actions (e.g., setup/setupadministrator.action) and the subsequent addition of accounts to the 'confluence-administrators' group. It correlates process execution, network request patterns, and local user account modifications to identify successful or attempted privilege escalation and configuration manipulation.
This rule detects potential keystroke logging activities on Android devices by monitoring the 'UniversalInputMonitor' accessibility service. This service is abused by the RatHat malware family and similar threats to capture user input, including passwords, PINs, and text entered into masked fields, by intercepting accessibility text events.
Detects the presence of PHP web shell code within the Admin Menu Editor Pro WordPress plugin directory. This rule targets indicators of a supply chain compromise where a legitimate plugin update is backdoored to include malicious PHP code designed for remote command execution via HTTP requests.
Detects successful API requests to sensitive administrative endpoints on WSO2 systems that lack a corresponding legitimate authentication event (session) from the same SourceIP and user pair, which may indicate the use of forged JWTs or authentication bypass exploitation (e.g., CVE-2026-5430).
Detects anomalous access to WSO2 API Manager Store and Publisher endpoints involving the retrieval of sensitive information like consumer keys and secrets. The rule specifically targets requests authenticated with JWTs that exhibit headers indicative of 'alg=none' or other unsupported/forged algorithm patterns, often associated with CVE-2026-5430 exploitation attempts. The rule uses statistical baseline monitoring to identify volume spikes in requests to these sensitive paths.
Detects attempts to exploit a vulnerability in WSO2 API Manager and Traffic Manager that allows for authentication bypass by utilizing a malformed JWT with the 'alg=none' header. Attackers can leverage this to impersonate users or bypass security controls by providing a crafted Bearer token in the Authorization header.
This rule identifies instances of the Acronis backup plugin for cPanel, WHM, or Plesk running on versions older than 1.9.3 HF3. This versioning threshold corresponds to the patch level required to mitigate the security vulnerability identified as CVE-2026-87886.
Detects unauthenticated path traversal attempts targeting the GitLab repository commits API, specifically checking for URL-encoded and plain path traversal patterns (e.g., '../') in requests to the commits endpoint. This behavior is indicative of attempts to exploit vulnerabilities like CVE-2026-85706 to read arbitrary files outside the repository scope.
This rule performs a wide aggregation of logs across proxy, cloud, GitHub, and network destination data sources. Because it lacks specific filtering logic or behavioral indicators, it does not detect any specific attack technique and serves only as a broad data collection query.
The rule detects the deletion of specific log files ('Udydn.out', 'server.log', or 'derby.log') which are often associated with application operations or internal debugging. Adversaries may delete these logs to conceal their activities, remove indicators of compromise, or interfere with forensic analysis.
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.

determine whether the request represents exploitation of CVE-2026-5430.
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.
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 potential exploitation of CVE-2025-3248 in Langflow by identifying suspicious inbound network traffic targeting the /api/v1/validate/code endpoint, correlated with subsequent python child processes containing base64 decoding and execution primitives such as eval, exec, or subprocess.
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).
Detects changes to Keycloak realm configurations that enable the 'Forgot password' (resetPasswordAllowed) setting. This specific configuration change is associated with temporary mitigation strategies for CVE-2026-18963 on known-vulnerable versions of Keycloak.
