MITRE ATT&CK
T1204.001 Malicious Link

The PDF file contains a link identified as a malicious redirector. This link, http://botcraftman.ru/..., is the primary indicator of malicious intent. The document body is heavily obfuscated and does not provide clear textual clues, but the presence of the malicious URL strongly suggests a social engineering attack aimed at redirecting the user to a harmful site. 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=alcohol+120+%D0%B4%D0%BB%D1%8F+windows+8+x64+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B1%D0%B5%D1%81%D0%BF%D0%BB%D0%B0%D1%82%D0%BD%D0%BE+%D1%82%D0%BE%D1%80%D1%80%D0%B5%D0%BD%D1%82&charset=utf-8
