MITRE ATT&CK
T1566.001 Spearphishing Attachment T1071.001 Web Protocols

The document contains a lure for 'Robux Place Rewards' and includes a prominent call-to-action link to a suspicious URL. The ML classifier strongly flagged this PDF as malicious, and the presence of an MFA lure heuristic suggests an attempt to harvest credentials or session tokens. The embedded URI and multiple other URLs point to sites offering game hacks or free in-game currency, consistent with phishing or malware distribution.

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.
