MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains multiple embedded URLs, including one identified as a potential download link for an application. The ML classifier strongly flagged this PDF as malicious, suggesting it's part of a campaign to distribute malware. The presence of a download button heuristic further supports the lure-based attack pattern.

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