MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a document body that explicitly mentions free Robux and game hacks, indicating a lure for users to download potentially malicious content. The ML classifier strongly flagged this PDF as malicious, supporting the suspicious verdict. While no scripts were directly extracted, the presence of external URIs and the nature of the lures suggest an attempt to redirect users to malicious sites or download further payloads.

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