MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for a "Minecraft Hack Client Download" and includes a high number of embedded URLs pointing to various game-related cheats and hacks. The presence of a "password-protected archive lure" heuristic suggests that the document may be intended to trick users into downloading an archive that requires a password, likely to bypass security scanning. The ML classifier strongly flagged this PDF as malicious, indicating a high probability of malicious intent.

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.
