Detects instances of an mcp-grafana server responding with an HTTP 200 status code to a 'tools/call' request without an Authorization header, indicating potential unauthenticated remote tool execution on a vulnerable or misconfigured server.
Detects upload requests targeting executable or server-side script file extensions.
Detects HTTP upload attempts to web directories where a request URL contains a suspicious double file extension pattern (e.g., a web shell extension followed by an image or document extension). This technique is commonly used to bypass web server or application-level security filters that check for forbidden file types by looking at the final extension while the server might execute the underlying script.
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 an unauthenticated exploitation attempt against Magento GraphQL endpoints, specifically targeting the 'styles' parameter. The attack pattern involves sending a malformed request to the /graphql endpoint with an 'X-TRACE-' header, which is indicative of the StyleSmuggler vulnerability exploit.
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 potential exploitation or unauthorized discovery of Programmable Logic Controllers (PLCs) by identifying the use of default SNMP community strings or unauthenticated S7comm protocol sessions.
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.
Detects the use of non-standard, unusual, or potentially dangerous HTTP methods within Caddy web server logs, which may indicate reconnaissance, web application exploitation, or attempts to abuse server functionalities like WebDAV.
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.
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 suspicious child process creation (e.g., cmd.exe, powershell.exe) originating from Java applications where the command line contains indicators of deserialization vulnerabilities (e.g., FilteredObjectInputStream, Log4jLogEvent). This pattern is often associated with exploitation of Java applications to gain remote code execution.
Detects files that present a valid PNG magic header at the start but contain embedded PostScript instructions. This pattern is commonly used to exploit vulnerabilities in image processing libraries like Ghostscript or ImageMagick, which may attempt to process the file as PostScript despite the misleading header.
Detects legacy RFB security-type 2 (VNC password) authentication negotiation against macOS Screen Sharing from external sources, indicating legacy-VNC administration or abuse of the CVE-2026-43760 legacy-auth path that retains root file-copy authority.
Detects a Ray raylet, gcs_server, or dashboard process spawning a calculator process (a near-certain PoC/exploit indicator) or a shell child process carrying suspicious network, encoding, or reverse-shell command-line indicators, consistent with post-exploitation of CVE-2025-62593. Known-legitimate pipeline package-install commands are filtered out to reduce noise from normal Ray job workers.
Detects a process other than screensharingd binding to macOS Screen Sharing port 5900 shortly after being newly spawned, indicating potential exploitation of the CVE-2026-43779 connection-interception logic flaw.
Detects HTTP requests to the attacker's WebApp-Form-Host operator panel managing compromised WordPress sites at scale (wp-uploading.php/wp-verifyup.php with activator parameters).
This rule detects potentially malicious, unauthenticated GraphQL mutation requests targeting common data modification operations ('delete', 'destroy', 'remove', 'update'). By checking for missing Authorization and Session tokens during frequent mutation attempts, it identifies potential exploitation attempts or unauthorized data manipulation attempts against an exposed GraphQL endpoint.
Detects the creation of .php files within the wp-content/uploads directory tree by common web server or PHP-FPM processes. This behavior is indicative of an adversary attempting to drop a web shell via file upload bypass vulnerabilities, such as those exploiting MIME-type manipulation.
Detects HTTP requests to the malicious 'verify' WordPress plugin serving the fake CAPTCHA ClickFix overlay.
Detects HTTP requests to StopAndProtect's WordPress webshells and malicious MU-plugin backdoor endpoints.
