MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for 'Coin Master Free Spins' and includes an external URI pointing to a suspicious domain. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of malicious intent. While no scripts were explicitly extracted, the presence of embedded URLs and the nature of the lure suggest the document is designed to redirect users to potentially harmful content or initiate further malicious downloads.

Machine Learning

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.
