MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a link to a known malicious redirector, botcraftman.ru, which is flagged as a critical threat. The ML classifier also strongly indicates maliciousness. While no scripts were explicitly extracted, the PDF structure and the malicious URL suggest an attempt to lure the user to a harmful site, likely for phishing or to download 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.
    URL http://botcraftman.ru/?lip&keyword=one+republic+native+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B0%D0%BB%D1%8C%D0%B1%D0%BE%D0%BC+%D1%82%D0%BE%D1%80%D1%80%D0%B5%D0%BD%D1%82&charset=utf-8
