This rule detects inbound network traffic attempting to exploit a path traversal vulnerability (CVE-2025-8088) related to RAR files and Alternate Data Streams (ADS). The detection logic specifically looks for a pattern indicative of path traversal attempts within the RAR file structure over raw TCP connections, excluding HTTP traffic. This exploit could allow an attacker to write files to arbitrary locations on a compromised system.

This rule detects network traffic indicative of a Windows Shortcut Link (LNK) file containing an unusually large amount of padded whitespace in its command line arguments. This technique is often used to obfuscate malicious commands or exploit vulnerabilities like ZDI-CAN-25373, which was a zero-day exploit related to Windows shortcuts. The rule specifically looks for the LNK file header signature and then uses a PCRE to identify repeated whitespace characters (tab, newline, vertical tab, form feed, carriage return, space) within the file data, suggesting padding for obfuscation or to bypass security controls.

This rule detects an attempt to exploit a path traversal vulnerability (CVE-2025-8088) in RAR files delivered via HTTP. The exploit leverages Alternate Data Streams (ADS) and specific path traversal patterns to potentially write files outside of the intended directory. The detection is based on the presence of 'STM' in the HTTP response body and a PCRE regex matching a specific path traversal pattern.

This rule detects the 'Zip Slip' vulnerability pattern within incoming ZIP archives. Specifically, it looks for the sequence '..\' (dot dot backslash) in the file data of a ZIP archive, which is indicative of an attempt to extract files outside of the intended directory. This vulnerability can lead to directory traversal and arbitrary file overwrite.

This rule detects attempts to exploit an insecure deserialization vulnerability (CVE-2025-53690) in Sitecore Experience Platform via exposed ASP.NET MachineKeys. It specifically looks for HTTP POST requests to '/sitecore/blocked.aspx' containing a '__VIEWSTATE' parameter with a highly encoded string, indicative of a crafted ViewState payload used in deserialization attacks.
