MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains embedded links and a primary external URI pointing to a site offering 'minecraft-svg-free-game-hack', suggesting a lure for downloading malicious content. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' indicates the document may instruct users to provide a password for an archive, a common tactic to bypass security scans. The ML classifier strongly flagged this PDF as malicious, supporting the conclusion that it is part of a malicious download campaign.

Heuristics 4

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

  • 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.
