MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs that lead to sites offering game hacks and free in-game currency, suggesting a lure for potentially unwanted software or scams. While no scripts were explicitly extracted, the ML classifier strongly indicated maliciousness, and the presence of external URIs points to a phishing or social engineering attempt. The document body is heavily obfuscated, preventing a deeper analysis of its specific content.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9953

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.
