MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple links to external websites, one of which is directly embedded in the document body and appears to be a lure for downloading game hacks. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the document's theme suggest it's designed to trick users into downloading malware, likely through a spearphishing attachment vector.

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