MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a document body that explicitly mentions 'Robux Hack' and 'Minecraft Free', indicating a lure for potentially malicious downloads. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were directly extracted, the presence of external URIs suggests an attempt to redirect the user to a site hosting a second-stage payload.

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