MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded links, forming a link farm, and a primary external URI pointing to a site offering 'Coin Master Daily Free Spins'. The document body, though partially corrupted, also contains references to game hacks and free in-game currency. This suggests a social engineering lure to drive traffic to potentially malicious or ad-filled websites. The presence of embedded links and the nature of the content strongly indicate a phishing or scam attempt.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9769

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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.
