MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document body and extracted URLs indicate a lure for free Robux and game hacks, suggesting a phishing or malware distribution attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports this assessment. While no scripts were explicitly extracted, the document's structure and content are designed to trick users into downloading further malicious content.

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