MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document contains an external URI pointing to a suspicious domain associated with game hacks. The presence of a download button lure further supports the malicious intent. Although no scripts were explicitly extracted, the PDF structure and embedded URLs suggest it's designed to trick users into downloading 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.
