MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to a game hack download. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect the user to a malicious site. While no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a lure for downloading potentially harmful content.

  • External URI info PDF_URI
    PDF contains an external URL action
