MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that advertises free in-game currency and hacks for popular games, aiming to trick users into downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a suspicious nature. While no scripts were explicitly extracted, the document's structure and content suggest it's a lure for further malicious downloads.

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.
