Detects a command-line pattern using a ping loopback command to create a delay, a technique used by malware like DarkTortilla/CHAMELEON#NET to evade automated sandbox analysis.
This rule detects attempts to exploit the Zip Slip vulnerability in inbound ZIP archives. It specifically looks for the sequence '../' within the file data of a ZIP archive, which indicates an attempt to write files outside of the intended directory during extraction.
This rule detects the presence of the PowerShell cmdlet 'Register-ScheduledTask' within an HTTP response body. This could indicate an attacker attempting to establish persistence on a compromised system by creating a scheduled task, potentially delivered via a web-based command and control channel or a malicious download.
This rule detects the string "schtasks" followed by "/end" and then "/tn" within the HTTP response body. This pattern indicates that a client is receiving a response that contains a command to end a scheduled task using the `schtasks` utility. This could be part of a command-and-control communication or a lateral movement attempt where an adversary is managing scheduled tasks on a compromised system.
This rule detects the presence of 'schtasks' followed by '/delete' and '/tn' (task name) in the HTTP response body with a 200 status code. This could indicate an attacker attempting to delete scheduled tasks on a compromised Windows system, potentially to remove forensic evidence or disrupt legitimate operations. The detection is case-insensitive and uses a PCRE to match the specific command structure.
This rule detects attempts to exploit CVE-2024-30043, a vulnerability in Microsoft SharePoint's SPXmlDataSource. The detection is based on the presence of specific content in HTTP response bodies, including '<!DOCTYPE', '<SharePoint:SPXmlDataSource', and 'DataFile="', combined with a PCRE regex matching file or SMB paths, indicating an attempt to fetch data via XML External Entity (XXE) injection.
This rule detects an attempted buffer overflow vulnerability (CVE-2025-9298) in Tenda routers. Specifically, it looks for HTTP POST requests to the '/goform/QuickIndex' URI where the 'PPPOEPassword' parameter contains an excessively long string (100 or more characters) that could lead to a buffer overflow.
This rule detects an attempt to exploit a buffer overflow vulnerability (CVE-2024-8573) in TOTOLINK devices. The exploit targets the `setParentalRules` function within the `/cgi-bin/cstecgi.cgi` endpoint, specifically looking for HTTP POST requests with multiple parameters (desc, week, sTime, eTime) containing excessively long values (100 or more characters), indicative of a buffer overflow attempt.
This rule detects attempts to exploit a critical authentication bypass vulnerability (CVE-2025-54309) in CrushFTP's WebInterface. The exploit leverages an alternative channel to bypass authentication, specifically targeting the '/WebInterface/function/' URI with a 'command=login' parameter and a 'crushadmin' string in the 'as2-to' HTTP header. Successful exploitation could lead to unauthorized administrative access.
