MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that promotes free in-game items and hacks for popular games. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a malicious site for further exploitation or download. No scripts were extracted from this sample, but the overall pattern indicates a phishing or malware distribution lure.

    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
