MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that advertises a "Coin Master Free Spins Hack Link", suggesting a lure for users to download potentially malicious content. The ML classifier also flagged this PDF as malicious with high confidence. No scripts were extracted, but the presence of external URIs and the ML detection strongly indicate a malicious intent to trick users into downloading a payload.

Heuristics 3

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
