MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly advertises a 'Coin Master 3.4 4 Free Download' and links to external resources. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple download-related URLs suggests a phishing or malware distribution attempt. No scripts were extracted, but the overall structure and content point to a social engineering lure for a game hack, likely leading to a malware download.

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.
