MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to 'netcdn.xyz', which are likely intended to redirect users to download malicious files or exploit kits. The ML classifier strongly flagged this PDF as malicious, and the presence of game-related lures suggests a social engineering tactic to entice users. No scripts were extracted, but the embedded URLs are the primary indicators of malicious intent.

  • Nyx PDF Classifier malicious score 0.9994

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.
