MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly flagged this PDF as malicious. The document body and extracted URLs indicate a lure for game-related cheats, specifically mentioning Roblox and Coin Master. The presence of embedded URLs suggests the document is intended to redirect users to download malicious content, likely a second-stage payload.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
