The RTF file contains embedded PHP source code for an IRC bot. The script is designed to connect to IRC servers, join specified channels, and respond to commands. It appears to be a tool for remote control and potentially coordinating malicious activities over IRC. The embedded source code is the primary indicator of this functionality.

Heuristics 2

  • PHP webshell / backdoor source critical WEBSHELL_PHP
    The file contains PHP server-side code with the signature of a webshell/backdoor (request input fed to a command/code-exec sink with a decoder/second sink (RCE backdoor)). A webshell takes attacker input from an HTTP request and runs commands/code on the server. Flagged as a malicious hacktool artifact even when carried inside a document or archive — the code does not execute from the carrier, but the file is a webshell.
  • PHP IRC bot source embedded in RTF high RTF_PHP_IRC_BOT_SOURCE
    RTF document contains PHP source code with IRC socket connection logic, IRC protocol commands, and bot-control indicators. The RTF is acting as a wrapper for bot source rather than an exploit that executes when opened.
