ET EXPLOIT_KIT LandUpdate808 Domain in DNS Lookup (virtvan .com)
ET ATTACK_RESPONSE PowerShell String Base64 Encoded Text.Encoding (V4dC5FbmNvZ) in DNS TXT Reponse
This rule detects HTTP POST requests to github.com's /login/device/code endpoint containing a 'client_id=' parameter in the request body. This pattern is indicative of a device code authentication flow, which could be leveraged in phishing attacks (device code phishing) to steal application access tokens or facilitate unauthorized access to GitHub accounts.
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.

ET INFO Remote Monitoring and Management (RMM) Tool in TLS SNI (gorelo-rmm .azurewebsites .net)
This rule detects attempts to exploit a deserialization vulnerability (CVE-2018-8421) in Microsoft SharePoint via a crafted workflow. The detection specifically looks for HTTP POST requests to the `/_vti_bin/webpartpages.asmx` endpoint containing `ValidateWorkflowMarkupAndCreateSupportObjects` and `workflowMarkupText` with CDATA, indicating an attempt to inject malicious XML.
ET ATTACK_RESPONSE HTML Smuggling Powershell Payload In href
This rule detects HTTP requests to archive.org for image files (png, jpg, jpeg, svg, gif, tiff) that have minimal request headers, specifically lacking both 'User-Agent' and 'Referer' headers. This behavior can be indicative of automated tools or malware attempting to retrieve content while trying to evade detection or hide their origin.
This rule detects attempts to exploit CVE-2021-20021, an unauthenticated arbitrary user creation vulnerability in SonicWall Email Security. The detection is based on HTTP GET requests to the '/createou' URI containing 'data=' in the request body, which is indicative of an exploitation attempt.
This rule detects inbound network traffic attempting to exploit an open redirect vulnerability within the Google APIs 'AddItNow' service. Specifically, it looks for requests to 'apis.google.com/additnow/l?__lu=' which could be used to redirect users to arbitrary malicious websites.
This rule detects attempts to exploit the Zip Slip vulnerability by identifying ZIP archive uploads containing directory traversal sequences ('../') within filenames. This technique allows attackers to write files outside the intended extraction directory, potentially leading to arbitrary file overwrite or remote code execution.
