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.
ET WEB_SPECIFIC_APPS VMware Workspace ONE Access OAuth2TokenResourceController ACS Authentication Bypass (CVE-2022-22956)
ET WEB_SPECIFIC_APPS Oracle E-Business Suite (EBS) Authentication Bypass (SyncServlet) (CVE-2025-61882)
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.
ET WEB_SPECIFIC_APPS Adobe ColdFusion Unauthenticated Remote Code Execution (CVE-2023-29300)
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.
ET WEB_SPECIFIC_APPS Oracle E-Business Suite (EBS) Template Manager Template Copy (CVE-2025-61882)
This rule detects an attempt to exploit a critical vulnerability (CVE-2025-31324) in SAP NetWeaver Visual Composer's Metadata Uploader. The exploit leverages unauthenticated HTTP GET or HEAD requests to the '/developmentserver/metadatauploader' URI, combined with specific characters in the URI parameters (semicolon, dollar sign, backtick, pipe, or their URL-encoded equivalents) that indicate an attempt to execute arbitrary commands. This vulnerability allows an unauthenticated attacker to achieve remote command execution on the affected SAP system.
This rule detects attempts to exploit the Zip Slip vulnerability within TAR archives. Specifically, it looks for the sequence `../` (dot dot slash) within the file data of an inbound TAR archive, which indicates an attempt to write files outside of the intended directory during extraction. This is a common technique used in Zip Slip attacks to achieve directory traversal and potentially overwrite critical system files or place malicious files in arbitrary locations.

ET WEB_SPECIFIC_APPS Oracle E-Business Suite (EBS) Template Manager Template File Add (CVE-2025-61882)
Detects post-exploitation behavior of LANDFALL spyware on Samsung devices. After exploiting CVE-2025-21042, the spyware uses LD_PRELOAD to inject a malicious shared object (.so) from its working directory (`/data/data/com.samsung.ipservice/files/`) into the benign `/system/bin/id` process, often via a shell wrapper.
This rule detects an attempted exploitation of an insecure deserialization vulnerability (CVE-2025-10035) in Fortra GoAnywhere MFT. Specifically, it looks for HTTP POST requests to the '/goanywhere/lic/accept/' URI containing the string 'bundle=' in the request body, which is indicative of an attempt to trigger the vulnerability.
This rule detects the 'Zip Slip' vulnerability pattern within TAR archive uploads. Specifically, it looks for the sequence '../' (dot dot slash) in the file data of a TAR archive, which indicates an attempt to traverse directories and potentially write files outside the intended extraction directory. This is a common technique used in Zip Slip attacks to achieve arbitrary file write.
This rule detects HTTP requests to the '.well-known/' directory that include common webshell file extensions (php, cfm, cgi, asp, aspx, jsp, rb, sh, py, pl). This activity is suspicious as the '.well-known/' directory is typically used for standardized metadata files (e.g., for ACME challenges, security.txt) and not for executable scripts. The rule specifically excludes requests from 'Let's Encrypt validation server' to reduce false positives.
This rule detects attempts to exploit CVE-2021-20021, an unauthenticated arbitrary user creation vulnerability in SonicWall Email Security. The rule specifically looks for HTTP POST requests to the '/createou' URI with 'data=' in the request body, indicating an attempt to create a new organizational unit or user.
ET EXPLOIT_KIT LandUpdate808 Domain in DNS Lookup (virtvan .com)
This rule detects an attempted remote code execution (RCE) vulnerability in Microsoft SharePoint, specifically CVE-2024-38018. The detection is based on an HTTP POST request targeting the `/_vti_bin/webpartpages.asmx` URI with a specific content pattern in the request body: `|3c|AttachedPropertiesShared|3e 2f|wE`. This pattern indicates an attempt to exploit a deserialization vulnerability within SharePoint's SPThemes functionality.
