This rule detects HTTP traffic to specific Visual Studio Code (VS Code) remote tunnel domains, specifically 'tunnels.api.visualstudio.com' or 'vscode.dev'. A high frequency of such connections (10 times within 60 seconds from the same source) is flagged as potential command and control (C2) activity, indicating the use of VS Code Remote Tunnels as a C2 channel.
This rule detects HTTP traffic where the client body contains a long string (100 or more characters) composed exclusively of uppercase letters and digits 2-7, potentially followed by padding characters. This pattern is indicative of custom alphabet base encoding, often used in Command and Control (C2) communications to obfuscate data.
This rule detects HTTP traffic where a shortened URL (from services like bit.ly, tinyurl, ow.ly, or t.co) is used in the HTTP referer header, and the HTTP response body contains the 'MZ' magic bytes, indicating a Windows executable file. This combination suggests a malicious redirect leading to the download of a payload, often associated with phishing or drive-by download attacks.
