MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that attempts to lure the user with free Robux gift card codes. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URIs suggests a download attempt. No scripts were extracted, limiting the ability to determine the exact payload or persistence mechanisms.

  • External URI info PDF_URI
    PDF contains an external URL action
