MITRE ATT&CK
T1059.001 PowerShell

The PDF file was flagged by a machine learning classifier and contains a link to a known malicious redirector. The embedded URL `http://botcraftman.ru/?lip&keyword=Zbrush+4+%D1%80%D1%83%D1%81%D0%B8%D1%84%D0%B8%D0%BA%D0%B0%D1%82%D0%BE%D1%80&charset=utf-8` is the primary indicator of malicious intent. The document body is heavily obfuscated and does not provide clear textual clues about its purpose.

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.
