MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual download button lure, suggesting it is designed to trick users into downloading potentially malicious software. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple suspicious URLs related to game hacks and free accounts reinforces this assessment. While no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a phishing or malware distribution attempt.

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