MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a lure for a "free game hack" and embeds a URL pointing to a suspicious domain. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of embedded URLs and the nature of the lure suggest an attempt to trick the user into downloading and executing a secondary payload, likely related to malware distribution.

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