MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The PDF document contains multiple embedded URLs and a prominent external URI pointing to sites offering game hacks and cheats. The ML classifier strongly flagged this PDF as malicious, and the presence of download-related text further supports a malicious intent to trick users into downloading potentially harmful files. No scripts were extracted, but the overall pattern suggests a lure for malware distribution.

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON

  • 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.
