MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a document body that attempts to lure the user into downloading game-related hacks. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it is designed to download a second-stage payload. No scripts were extracted, but the overall pattern indicates a phishing or malware distribution attempt.

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
