MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains numerous URLs related to game hacks and exploits, including a primary URL that appears to host a downloadable script. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs and a 'download button' heuristic further supports a malicious intent to trick users into downloading potentially harmful content. No scripts were extracted, but the overall structure and content point to a social engineering attack.

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