MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an external URI pointing to a suspicious URL, likely intended to deliver a malicious payload. The document body, though heavily obfuscated, contains references to game-related cheats and the same suspicious URL, reinforcing the lure. The ML classifier also flagged this PDF as malicious, increasing confidence in its malicious intent.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
