MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicates maliciousness, and the document body contains numerous links to external websites promising free in-game currency or items for popular games like Roblox and Coin Master. The presence of external URIs and the overall theme suggest a phishing or scam attempt designed to redirect users to potentially malicious sites. No scripts were extracted from this sample, but the embedded URLs are the primary indicators of malicious intent.

  • 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.
