MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and lures users with promises of free in-game items, a common tactic for distributing malware. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it is designed to download further malicious content. No scripts were extracted, but the overall structure and content indicate a phishing or malware distribution attempt.

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