T1566.001 Spearphishing Attachment

The PDF contains embedded links that redirect to a URL associated with a "hacked client" download, indicating a lure for potentially malicious software. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms the presence of malicious redirector infrastructure. While no scripts were explicitly extracted, the document body and embedded URLs suggest a social engineering attempt to trick users into downloading malware.

  • Nyx PDF Classifier malicious score 0.9969

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.
