MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that promotes 'free Robux' and game hacks, indicating a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a suspicious nature. While no scripts were explicitly extracted, the overall context suggests an attempt to trick users into downloading a second-stage payload.

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