The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL 'http://botcraftman.ru/?lip&keyword=%D0%A1%D0%B5%D1%80%D0%B2%D0%B5%D1%80+%D0%B4%D0%BB%D1%8F+naruto+naiteki+kensei+r1&charset=utf-8' is the primary indicator of malicious intent. The file was authored using wkhtmltopdf, which can sometimes be used to package malicious content.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • 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.
