Detects malicious SQL injection attempts targeting WordPress REST API endpoints that attempt to forge post parameters by injecting self-referential cycles. The pattern specifically looks for 'UNION SELECT' combined with 'author_exclude' and manipulated 'post_parent' values, matching known exploitation patterns for the wp2shell vulnerability (CVE-2026-63030 / CVE-2026-60137).
Detects HTTP traffic patterns characteristic of suo5 and Neo-reGeorg web shell tunnels. These tools facilitate bidirectional communication through JSP endpoints (e.g., /jmx/suo5.jsp, /common/themes/top_css.jsp) by utilizing hardcoded proxy identifiers in HTTP headers. This behavior is indicative of a compromised web server acting as a pivot point for command-and-control operations.
Detects the execution of sendmail via a shell (sh, bash, dash) spawned by a web server process (Apache, Nginx, httpd) where the process working directory matches the wp2shell plugin pattern (wp2shell_<hex>). This is indicative of remote code execution or web shell activity associated with the wp2shell vulnerability, where the attacker uses sendmail for exfiltration or command output delivery.
Detects the wp2shell unauthenticated SQL injection chain (CVE-2026-63030 / CVE-2026-60137) abusing the REST API batch-route confusion via author_exclude/author__not_in parameters against wp-json/wp/v2/posts or wp-json/batch/v1, where the extraction result reflects the WordPress 6.9 $wp$2y$ bcrypt-over-HMAC-SHA384 hash marker in the request query or response body. Requires both the specific unauthenticated REST SQLi vector AND the hash-format marker to fire, excluding legitimate authenticated admin export/reporting tools that reference wp_users through normal means.
Detects attempts to exploit the WordPress wp2shell vulnerability (CVE-2026-63030/CVE-2026-60137) by correlating the identification of a vulnerable WordPress version (6.9.0-6.9.4 or 7.0.0-7.0.1) via response banners with anomalous Batch REST API requests utilizing the 'author__not_in' parameter.
Detects instances where common web server processes (such as php-fpm, apache, nginx, or w3wp) spawn a command interpreter (sh, bash, or cmd.exe). This pattern is highly indicative of potential web shell activity, where an adversary executes commands on the underlying host after exploiting a web application.
This rule detects proxy requests directed to the legitimate Microsoft OAuth 2.0 device authorization endpoint (/common/oauth2/deviceauth). This activity is indicative of OAuth device code phishing, where a user is tricked into entering a malicious or attacker-provided device code into the legitimate Microsoft device login page to complete an authentication flow and grant unauthorized access to an attacker-controlled application.
Detects the wp2shell unauthenticated SQL injection chain (CVE-2026-63030 / CVE-2026-60137) abusing the REST API batch-route confusion via author_exclude/author__not_in parameters against wp-json/wp/v2/posts or wp-json/batch/v1, where the extraction result reflects the WordPress 6.9 $wp$2y$ bcrypt-over-HMAC-SHA384 hash marker in the request query or response body. Requires both the specific unauthenticated REST SQLi vector AND the hash-format marker to fire, excluding legitimate authenticated admin export/reporting tools that reference wp_users through normal means.
Detects attempts to perform error-based SQL injection against WordPress instances associated with the wp2shell exploit chain. The rule monitors for the use of MySQL functions EXTRACTVALUE or UPDATEXML within query parameters that are typically targeted by the exploit (author_exclude, author__not_in) or when interacting with the batch REST endpoint.

Detects web server processes (Apache, Nginx, PHP-FPM) spawning a system shell to execute compound commands containing discovery utilities (like id, whoami, hostname, uname, or find) within a 'wp-content/plugins' directory. This behavior is indicative of post-exploitation activity following a remote code execution vulnerability, such as those associated with the wp2shell attack pattern.
Detects silent browser-side cryptocurrency wallet fingerprinting via EIP-6963 discovery, window.ethereum probing, and wallet-extension enumeration (e.g. MetaMask, Solana) occurring together, excluding known legitimate dApp/wallet-connect domains, consistent with BlueNoroff's pre-payload wallet profiling.
Detects web server processes (Apache, Nginx, PHP-FPM) spawning a system shell to execute compound commands containing discovery utilities (like id, whoami, hostname, uname, or find) within a 'wp-content/plugins' directory. This behavior is indicative of post-exploitation activity following a remote code execution vulnerability, such as those associated with the wp2shell attack pattern.

Detects attempts to perform error-based SQL injection against WordPress instances associated with the wp2shell exploit chain. The rule monitors for the use of MySQL functions EXTRACTVALUE or UPDATEXML within query parameters that are typically targeted by the exploit (author_exclude, author__not_in) or when interacting with the batch REST endpoint.
Detects suspicious batch requests to the WordPress REST API (/wp-json/batch/v1) containing both a DELETE operation on category ID 0 and a POST operation to the core block-renderer, which is characteristic of attempts to exploit vulnerabilities like CVE-2024-27956 to achieve unauthenticated remote code execution.
Detects the execution of sendmail via a shell (sh, bash, dash) spawned by a web server process (Apache, Nginx, httpd) where the process working directory matches the wp2shell plugin pattern (wp2shell_<hex>). This is indicative of remote code execution or web shell activity associated with the wp2shell vulnerability, where the attacker uses sendmail for exfiltration or command output delivery.

Detects anomalous server responses for WordPress REST API requests targeting /wp/v2/categories/0 where the error message 'block_cannot_read' is returned instead of the expected 'rest_term_invalid'. This behavior is indicative of attempted exploitation using the wp2shell batch-handler desync vulnerability.
