MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a URL that points to a file advertised as a 'roblox-project-pokemon-dll-hack-game-hack'. This, combined with the ML classifier flagging the PDF as malicious and the presence of a visual download button lure, strongly suggests an attempt to trick the user into downloading a malicious payload. No scripts were extracted, but the overall context points to a downloader or dropper.

Heuristics 3

  • 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.
