MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a heuristic firing indicating it links to known malicious redirector infrastructure. The embedded URL `http://botcraftman.ru/...` is identified as a malicious redirector. While no scripts were explicitly extracted, the PDF structure and the presence of embedded URLs suggest an attempt to lure the user to a malicious site, likely for further exploitation or credential harvesting.

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=%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B0+%D1%81%D1%82%D0%B0%D0%BD%D0%BE%D0%BA+%D1%87%D0%BF%D1%83&charset=utf-8
