MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file was flagged by a critical heuristic for linking to known malicious redirector infrastructure. The embedded URL http://botcraftman.ru/?lip&keyword=warhammer&charset=utf-8 is identified as a malicious redirector. While no scripts were explicitly extracted, the nature of PDF redirects often involves JavaScript to facilitate the redirection, hence the inclusion of T1059.007.

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.
