The PDF contains a critical heuristic firing indicating it links to known malicious redirector infrastructure. The embedded URL, 'https://ttraff.cc/pify?keyword=utility+belt+gungeon', is the primary indicator of malicious intent. The ML classifier also strongly flagged this PDF as malicious. The document body, though heavily obfuscated, contains the same URL, reinforcing the redirection attempt.

  • Embedded URL info EMBEDDED_URL
