MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for free in-game items and currency, directing users to external URLs. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URIs suggests an attempt to download further content or redirect users to malicious sites. While no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a phishing or scam attempt.

Machine Learning

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
