MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that attempts to lure the user into downloading a file related to game cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it is designed to redirect the user to a download site. No scripts were extracted, but the overall pattern is consistent with a phishing or scam document designed to deliver a secondary payload.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
