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

The PDF contains embedded links and a visual download button, directing users to external resources. One of these links, https://netcdn.xyz/app/406889139/coin-master-3.5-16-hack-apk-game-hack, is flagged as a malicious redirector. The document body, though heavily obfuscated, contains references to 'Coin Master' and 'hack apk', suggesting a lure for potentially unwanted or malicious software.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8948

Heuristics 3

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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
  • 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.
