MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that lure the user into downloading a file by promising game-related cheats. The ML classifier strongly indicates maliciousness, and the presence of multiple suspicious URLs suggests a phishing or scam attempt. While no scripts were explicitly extracted, the PDF format can embed JavaScript, which could be used to facilitate the download or redirect the user.

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.
