MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a link to a known malicious redirector. The embedded URL 'http://botcraftman.ru/?lip&keyword=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D1%81%D0%BA%D0%B0%D0%B9%D0%BF+%D0%B4%D0%BB%D1%8F+nokia+n95&charset=utf-8' is flagged as malicious. This indicates the document's primary purpose is to lure the user to this external resource, which is a common tactic for phishing or distributing further malware.

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.
