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

The PDF contains a lure for downloading an application, indicated by the document body and a high-severity heuristic for password-protected archive handoffs. It also includes an external URI pointing to a suspicious download link, suggesting the document is designed to trick users into downloading malware disguised as a game or application. The presence of a benign Wikipedia link does not detract from the 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

    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.
