MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs that promise free in-game currency (Robux, spins), a common lure for phishing and scam sites. The ML classifier strongly flagged this PDF as malicious. While no scripts were directly extracted, the presence of external URIs and the document's deceptive content suggest an attempt to redirect users to malicious websites.

Heuristics 3

  • External URI info PDF_URI
    PDF contains an external URL action
  • PDF differential parser failed info PDF_DIFFERENTIAL_PARSE_FAILED
    The cross-check parser (pdfminer.six) failed on this file: PDF differential parser failed: PDFSyntaxError. Static heuristics still ran and any of their findings above are valid; only the differential cross-check signal is missing.
  • 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.
