MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document body and extracted URLs indicate a lure for free in-game currency or items related to games like Coin Master and Roblox. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests it is designed to redirect users to potentially harmful sites. No scripts were extracted, but the overall pattern suggests a phishing or scam attempt.

  • 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.
