T1566.001 Spearphishing Attachment T1204.002 Malicious File

This PDF document was flagged by an ML classifier as malicious. It contains multiple embedded URLs pointing to sites offering game hacks and free in-game currency, suggesting a lure for users seeking such content. The heuristic indicating a password-protected archive handoff suggests that the downloaded content may be encrypted to evade security checks.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

Heuristics 4

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
