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

The PDF file contains a link identified as belonging to known malicious redirector infrastructure. This heuristic strongly suggests the document's purpose is to lure the user to a harmful website. The link points to http://botcraftman.ru/, which is flagged for malicious redirection. 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.
    URL http://botcraftman.ru/?lip&keyword=%D1%81%D0%B8%D0%BC%D1%83%D0%BB%D1%8F%D1%82%D0%BE%D1%80+dj+%D0%BF%D1%83%D0%BB%D1%8C%D1%82%D0%B0&charset=utf-8
