MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document contains multiple embedded URLs pointing to sites offering in-game currency or virtual items, likely as a lure. The heuristic for a visual download button further supports the phishing pretext. The primary external URI, 'https://netcdn.xyz/app/406889139/get-free-food-in-coin-master-game-hack', is likely the intended destination for the user to download a payload.

  • 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.
