MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains multiple URLs and text related to obtaining free in-game currency, such as 'Free Robux'. The presence of embedded URLs and a high ML classifier score strongly suggests malicious intent, likely to trick users into downloading a second-stage payload. No scripts were extracted from this sample, but the overall pattern indicates a phishing or scam attempt.

Heuristics 3

  • 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.
