MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains a lure for free Robux, a virtual currency for the Roblox game, and includes an external URI pointing to a suspicious download URL. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were extracted, the presence of embedded URLs and the lure suggest an attempt to trick the user into downloading and executing a secondary payload.

  • External URI info PDF_URI
    PDF contains an external URL action
