MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for a 'Coin Master Hack' and embeds multiple URLs pointing to potentially malicious content or scam pages. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a call-to-action button further supports a malicious intent to redirect users to harmful sites or downloads. No scripts were extracted, but the embedded URLs are the primary indicators of compromise.

  • 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.
