MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a lure for a game hack, directing users to a URL that likely hosts a malicious payload. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs and a visual download button further supports a phishing or malware distribution attempt. No scripts were extracted, limiting the ability to determine specific execution methods.

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