MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded JavaScript and a prominent URL suggesting a download lure for a game hack. The ML classifier strongly flagged this PDF as malicious, and the presence of JavaScript indicates an attempt to execute code. The document body and extracted URLs reinforce the theme of providing game cheats or hacks, which is a common social engineering tactic.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

Heuristics 4

  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • 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.
