MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and text lures related to 'free spins' and 'free robux', indicating a phishing or scam attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it is designed to redirect users to download further content. No scripts were extracted, but the overall pattern points to a social engineering attack.

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