The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL http://botcraftman.ru/... is flagged as malicious. This suggests the document is designed to lure users to a harmful website, likely for phishing or malware delivery. No scripts were extracted, limiting further analysis of the payload.

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.
