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%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%BC%D0%BE%D0%B4+%D0%BD%D0%B0+%D0%B6%D0%B5%D0%BD%D1%83+%D0%B2+%D0%BC%D0%B0%D0%B9%D0%BD%D0%BA%D1%80%D0%B0%D1%84%D1%82+1+5+2&charset=utf-8' is the primary indicator of malicious intent. This suggests the document is designed to lure users to a malicious website, likely for phishing or malware delivery. No scripts were extracted from this sample.

Heuristics 2

  • 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.
