MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and document body text that lure the user into downloading game-related cheats, such as 'free Coin Master cards'. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URIs suggests it is designed to redirect users to malicious download sites. No scripts were extracted from this sample, but the overall pattern indicates a phishing or social engineering attempt to deliver a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9971

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.
