MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that lure the user into downloading a file by promising free in-game currency for popular games like Roblox and Minecraft. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to download a secondary payload. No scripts were extracted from this sample.

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