MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an external URI pointing to a file named 'coin-master-update-2021-game-hack', suggesting a lure for downloading potentially malicious content. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the presence of embedded URLs and the overall structure indicate an attempt to trick the user into downloading a second-stage payload.

  • External URI info PDF_URI
    PDF contains an external URL action
