MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one that appears to be a direct download link for a 'Coin Master Free Spins Link App'. The ML classifier strongly flagged this PDF as malicious, and the presence of a visual download button heuristic further supports a phishing or scam attempt. Although no scripts were explicitly extracted, the PDF structure and embedded URIs suggest an attempt to redirect users to malicious sites, likely for credential harvesting or malware distribution.

  • External URI info PDF_URI
    PDF contains an external URL action
