This rule detects attempts to exploit an XML External Entity (XXE) injection vulnerability in Adobe Experience Manager Forms. The detection logic specifically looks for HTTP POST requests to the '/edcws/services/urn:EDCLicenseService' URI containing '<EDCSecurity>' and '<!ENTITY' patterns in the request body, along with a PCRE regex to identify the XXE payload structure.
This rule detects attempts to exploit an insecure deserialization vulnerability (CVE-2025-49533) in Adobe Experience Manager Forms. The detection is based on specific HTTP URI patterns and content within the request body, looking for '/FormServer/servlet/GetDocumentServlet' followed by 'serDoc=' and 'H4sIAA', which are indicators of a serialized object being sent to the server.
This rule detects attempts to exploit the Zip Slip vulnerability by identifying the sequence '../' within a ZIP archive being uploaded to a server. This pattern indicates an attempt to write files outside the intended directory, potentially leading to arbitrary file overwrite or remote code execution.
This rule detects the presence of the PowerShell cmdlet 'Start-ScheduledTask' within the HTTP response body. This could indicate an attacker attempting to establish persistence on a compromised system by creating scheduled tasks, potentially delivered via a web-based command and control channel or during an exploit.
This rule detects the presence of the PowerShell cmdlet 'Disable-ScheduledTask' within the HTTP response body. This could indicate an attacker attempting to disable scheduled tasks on a compromised system, potentially to remove persistence mechanisms or hinder forensic analysis. The rule specifically looks for a successful HTTP status code (200) and the 'disable-scheduledtask' string, optionally preceded by '-taskname' or '-taskpath'.
This rule detects HTTP GET requests to github.com for PNG files where the User-Agent header contains "WindowsPowerShell". This combination could indicate an attempt to download malicious content or C2 instructions disguised as an image file using PowerShell.
This rule detects attempts to exploit a buffer overflow vulnerability in the `SetNetControlList` function of Tenda routers. Specifically, it looks for HTTP POST requests to the `/goform/SetNetControlList` URI where the `list` parameter in the request body is excessively long (100 characters or more). This vulnerability (CVE-2025-9087, CVE-2025-29215, CVE-2025-1897) could lead to denial of service or arbitrary code execution.
This rule detects an attempt to exploit a buffer overflow vulnerability (CVE-2025-9297) in Tenda networking equipment. Specifically, it looks for HTTP POST requests to the '/goform/wxportalauth' URI where the 'type' parameter in the request body contains a string of 100 or more characters, indicating a potential buffer overflow attempt.
This rule detects attempts to exploit a command injection vulnerability in B-Link devices, specifically targeting the `/goform/set_hidessid_cfg` endpoint with the `enable` parameter. Attackers can inject commands by manipulating the `enable` parameter in a POST request, indicated by the presence of command separators like semicolon, newline, backtick, pipe, or dollar sign.
This rule detects inbound network traffic associated with the Braodo Loader malware. It specifically looks for a unique byte sequence and a specific string within the HTTP response body, indicating the download or communication related to this loader.
This rule detects the inbound transfer of a KoiStealer payload over HTTP. It specifically looks for unique string patterns within the HTTP response body that are indicative of the KoiStealer malware, including specific context definitions and keywords like 'CONTEXT_i386', 'CONTEXT_i486', 'CONTEXT_CONTROL', and 'CONTEXT_INTEGER'. This suggests the rule is designed to identify the download of the malware executable or a component of it.
This rule detects the presence of 'activeMQConnectionURL' and 'tcp://' within HTTP response bodies, which is indicative of a Commvault server exposing its hostname or connection details. This information could be leveraged by attackers for reconnaissance or to identify vulnerable Commvault instances.

This rule detects attempts to exploit a vulnerability in Xerox FreeFlow Core (CVE-2025-8356) that allows for arbitrary file upload and directory traversal. The detection logic looks for HTTP POST requests with a specific content type ('multipart/related' and 'application/vnd.cip4-jmf+xml') and a 'Content-Disposition: attachment; filename="' header, combined with a PCRE regex matching directory traversal patterns (e.g., '../', '..\'). This indicates an attacker is trying to upload a malicious file or traverse directories on the server.
