MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious, and it contains numerous embedded URLs pointing to sites offering game hacks and cheats. The document body, though truncated, also contains a suspicious URL, suggesting a lure for users to download potentially harmful content. No scripts were extracted, but the presence of external links and the high ML score indicate a likely attempt to deliver a second-stage payload.

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.
