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

The PDF document contains embedded URLs and a document body that explicitly promises a "hack" for Coin Master, suggesting a social engineering lure. The ML classifier strongly flagged this PDF as malicious, and the presence of multiple external URLs indicates an attempt to redirect the user to download malicious content. No scripts were extracted from this sample.

  • External URI info PDF_URI
    PDF contains an external URL action
