MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual call-to-action, strongly suggesting an attempt to trick the user into downloading malicious content. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of external URLs indicates a potential download or redirection to a second-stage payload.

  • External URI info PDF_URI
    PDF contains an external URL action
