MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier and PDF URI heuristic strongly indicate malicious intent. The document body and embedded links promote 'free spin links' and 'robux' which are common lures for downloading malware or engaging in scams. The presence of multiple URLs suggests an attempt to redirect the user to a malicious download site.

  • Nyx PDF Classifier malicious score 0.9971

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.
