MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains embedded URLs and a call-to-action phrase, strongly suggesting a lure for users to download potentially malicious content. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lures (game hacks) indicate a likely attempt to deliver a second-stage payload.

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.
