MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a lure for 'Free Robux' and a prominent call-to-action link to a suspicious URL. The heuristic 'SE_MFA_LURE' suggests the document may be designed to harvest credentials or session tokens by impersonating a verification process. No scripts were extracted, but the embedded URL is the primary indicator of malicious intent.

  • Nyx PDF Classifier clean score 0.0718

Heuristics 4

  • MFA / one-time-code harvesting lure high SE_MFA_LURE
    Document asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
