MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded URL pointing to a domain associated with game hacks and exploits. The ML classifier strongly flagged this PDF as malicious, and the presence of a download button lure reinforces the phishing attempt. The document body, though heavily obfuscated, contains references to 'free Robux' and a URL that likely leads to a second-stage payload.

  • 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.
