MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure related to game cheats and a fake PayPal checkout, directing users to download a file from a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and embedded URLs suggest a download or redirection to a malicious payload. While no scripts were explicitly extracted, the PDF structure and embedded URIs indicate a malicious workflow designed to trick users into downloading malware.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
