MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent link disguised as a download button for a game hack. The ML classifier strongly flagged this PDF as malicious, and the embedded URL points to a suspicious domain likely hosting a malicious payload. No scripts were extracted, but the overall structure and content suggest a social engineering attempt to trick users into downloading potentially harmful software.

  • External URI info PDF_URI
    PDF contains an external URL action
