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

The document presents itself as a free download for Minecraft, a common lure for users seeking game cheats or hacks. It contains an embedded URI pointing to a suspicious domain, likely serving as a download source for a malicious payload. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests that the user might be instructed to decrypt a downloaded archive, a common tactic to bypass security filters.

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.
