T1059.001 PowerShell

The PDF file contains embedded links that redirect to malicious infrastructure, disguised as a search result for educational material. The primary heuristic indicates a PDF redirector link to ggtraff.ru, which is known malicious. The document body, though heavily obfuscated, contains the same URL, suggesting a lure to download further malicious content. No scripts were extracted from this sample.

Heuristics 2

  • 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.
  • 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.
