MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that advertises hacks for popular games, strongly suggesting a lure for users to download malicious content. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the presence of external URIs and the overall context indicate a phishing or malware distribution attempt, likely initiated via a spearphishing attachment.

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