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

The PDF contains embedded JavaScript and external URIs pointing to sites offering game hacks and free currency, strongly suggesting a phishing or malware distribution attempt. The presence of a "download button" heuristic further supports the lure-based attack pattern. The embedded JavaScript likely facilitates the download and execution of a second-stage payload from one of the provided URLs.

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.
