MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs that lead to sites offering free in-game items and currency, a common lure for malware distribution. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to download a secondary payload or redirect the user to a malicious site. No scripts were extracted from this sample, but the overall structure and embedded links point towards a phishing or malware delivery attempt.

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.
