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

The PDF file contains an embedded link that redirects to a known malicious domain, botcraftman.ru. This indicates a phishing attempt or a drive-by download lure. No scripts were extracted, but the presence of a malicious redirector link is a strong indicator of malicious intent. The file was generated by wkhtmltopdf, which is sometimes used to package malicious content.

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%A0%D0%B0%D0%BD%D0%B5%D1%82%D0%BA%D0%B8+6+%D1%81%D0%B5%D0%B7%D0%BE%D0%BD+%D0%BE%D0%BF%D0%B8%D1%81%D0%B0%D0%BD%D0%B8%D0%B5+%D1%81%D0%B5%D1%80%D0%B8%D0%B9&charset=utf-8
