MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains an embedded URI pointing to a file named 'wurst-1.15-game-hack'. This, combined with the ML classifier flagging the PDF as malicious and the presence of a 'download button' heuristic, strongly suggests an attempt to trick the user into downloading a malicious executable. The document body, though heavily obfuscated, contains references to the same URL.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9632

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.
