MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains an embedded URI pointing to a URL that promises 'Coin Master Free Pet Food Links'. This, combined with the ML classifier flagging the PDF as malicious, strongly suggests a phishing or scam attempt. The document body, though heavily obfuscated, contains references to the same malicious URL, reinforcing the lure.

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.
