MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that promotes free Robux and game hacks, indicating a lure for potentially unwanted software or malware. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of external URIs and the document's deceptive content suggest it's designed to redirect users to malicious download sites.

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