MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a document body that explicitly advertises "free spins" and "hacks" for popular games, aiming to trick users into downloading further malicious content. The ML classifier strongly flagged this PDF as malicious, supporting the conclusion that it is part of a phishing or malware distribution scheme. No scripts were extracted, but the presence of external URIs and the document's deceptive content indicate a high likelihood of it being a lure for further compromise.

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.
