MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for free Robux and other in-game currencies, directing users to download an application from a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent. No scripts were extracted from this sample, but the document body and heuristics indicate a phishing or scam attempt.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
