T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a link to a known malicious redirector, botcraftman.ru. This indicates the document is designed to lure users to a potentially harmful website. The file's metadata suggests it was generated by wkhtmltopdf, a tool often used to create PDFs from web content, which could be part of a phishing or malware delivery chain. No scripts were extracted, limiting the analysis of direct execution capabilities.

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%84%D0%B8%D0%B7%D0%B8%D0%BA%D0%B0+8+%D0%BA%D0%BB%D0%B0%D1%81%D1%81+%D0%BF%D0%B5%D1%80%D1%8B%D1%88%D0%BA%D0%B8%D0%BD+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+pdf&charset=utf-8
