MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for free Robux and game hacks, directing users to external URLs. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it is intended to download further malicious content or redirect users to phishing sites. No scripts were extracted from this sample, but the overall pattern indicates a social engineering attempt to trick users into downloading potentially harmful files.

  • 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.
