MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for obtaining free in-game currency for popular games, directing users to download an application from a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent to trick users into downloading potentially harmful content. No scripts were extracted, but the overall pattern suggests a phishing or social engineering attack.

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.
