MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for free Robux, a virtual currency for the Roblox game, and includes a direct link to download an application. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to a download site. No scripts were extracted from this sample, but the overall structure and content suggest a phishing or malware distribution attempt.

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.
