MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to a "tiktok-free-like-2021-game-hack". The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to download a second-stage payload. The document body, though partially obfuscated, also contains references to game hacks and cheats, reinforcing the lure.

  • 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.
