MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a critical heuristic firing indicating a link to a known malicious redirector. The embedded URL, http://botcraftman.ru/..., is likely the initial stage of a phishing or malware delivery chain. No scripts were extracted, and the document body was not sufficiently readable to provide further context on the lure.

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%8D%D0%BA%D0%B7%D0%B0%D0%BC%D0%B5%D0%BD%D0%B0%D1%86%D0%B8%D0%BE%D0%BD%D0%BD%D1%8B%D0%B5+%D0%B2%D0%BE%D0%BF%D1%80%D0%BE%D1%81%D1%8B+%D0%BF%D0%BE+%D1%84%D0%B8%D0%B7%D0%B8%D0%BA%D0%B5+10+%D0%BA%D0%BB%D0%B0%D1%81%D1%81&charset=utf-8
