Detects a Redis process connecting to a suspected rogue replication master (using non-standard ports or known malicious IPs) followed by a file modification to a system cron directory. This sequence is indicative of a Redis Rogue Replication exploit where a crafted RDB file is used to achieve persistence by writing a malicious entry to a cron job.

This rule detects a suspicious sequence of events indicative of a Redis Lua sandbox escape. It monitors for a network connection to Redis (port 6379) followed shortly by the redis-server process reading the system's /etc/passwd file, which is a known indicator of an attempted arbitrary file read via the EVAL command.

Detects indicators associated with the exploitation of CVE-2025-3248 in Langflow. The rule identifies anomalous web requests targeting the /api/v1/validate/code endpoint, subsequent suspicious process creation (base64 encoded payloads in Python/shell), and network communication with identified command and control (C2) or data exfiltration IP addresses. It also includes alerts for observed contact with known extortion email addresses.

This rule detects incoming HTTP POST requests to the '/api/v1/validate/code' endpoint of a Langflow instance. The rule specifically looks for a JSON key 'code' containing a large, potentially base64-encoded string, which indicates an attempt to exploit CVE-2025-3248 to achieve unauthenticated remote code execution.

Detects web requests to 'wp-admin/theme-install.php' containing suspicious query parameters that indicate an attempt to force an unauthenticated theme installation via a Cross-Site Request Forgery (CSRF) exploit (Click2Shell). The rule identifies requests with malicious payloads in the 'theme' parameter, specifically looking for indicators that attempt to bypass CSRF protections when originating from an external site or a non-admin session context.

Detects attempts to exploit CVE-2021-33044, an authentication bypass vulnerability in Dahua NetKeyboard hardware. The rule triggers when a POST request containing 'global.login', 'clientType: NetKeyboard', and 'loginType: Direct' is observed, which allows unauthorized access by manipulating authentication parameters.

This rule detects an attempt to exploit CVE-2021-33045, an authentication bypass vulnerability in certain Dahua products. An attacker can bypass authentication by sending a crafted HTTP POST request to the application, specifically using a loopback authentication type with a local IP address (127.0.0.1) in the login payload.

The following analytic detects executable file formats being created within the Confluence main directory.
This can be indicative of exploitation of the Confluence web services to stage malware.
This won't catch adversaries who modify the output location outside the Confluence directory when exploiting.

The following analytic identifies attempts to inject Log4Shell JNDI payloads via web calls. It leverages the Web datamodel and uses regex to detect patterns like `${jndi:ldap://` in raw web event data, including HTTP headers. This activity is significant because it targets vulnerabilities in Java web applications using Log4j, such as Apache Struts and Solr. If confirmed malicious, this could allow attackers to execute arbitrary code, potentially leading to full system compromise. Immediate investigation is required to determine if the attempt was successful and to mitigate any potential exploitation.

Detects incoming HTTP requests where the 'pagename' parameter contains directory traversal sequences (e.g., '../', '..%2f'). These attempts are typically indicative of automated vulnerability scanning or exploitation attempts targeting WordPress page-template resolution logic, specifically related to CVE-2026-87902.

Detects rapid, machine-speed, sequential attack-path adaptation by suspected AI agent binaries. The rule monitors for a correlation of four stages occurring within a tight 20-minute window: 1) Failed service connections across three or more distinct protocols (SMB, SSH, HTTP, RDP, WinRM), 2) Credential access attempts (Logon events or execution of known credential-dumping tools), and 3) A lateral movement pivot to a new, previously un-targeted internal destination. The rule specifically keys on the InitiatingProcessId and InitiatingProcessCreationTime to ensure the sequence is attributed to a single process instance, distinguishing it from human manual penetration testing activity. Covers T1190, T1210, T1078

These rules detect various exploitation attempts targeting SharePoint to bypass SafeControls, an security mechanism used to restrict the types of controls allowed in web parts. The patterns match suspicious Register directives and markup injection techniques often associated with remote code execution or privilege escalation, as identified in CVE-2026-65660.

Detects the IIS worker process (w3wp.exe) used by SharePoint loading a specific combination of assemblies (PresentationFramework.dll, System.Xaml.dll, and System.Data.Services.dll). This behavior is indicative of an ExpandedWrapper/XamlServices.Parse() insecure deserialization gadget chain, typically associated with the exploitation of vulnerabilities like CVE-2026-65660, which enables fileless in-memory code execution.
