MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links disguised as guides for obtaining free in-game currency for Coin Master and Roblox. The presence of external URIs and a high ML classifier score strongly suggest malicious intent. The document body and extracted URLs indicate a lure for potentially malicious content or phishing, likely delivered as a spearphishing attachment.

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.
