The PDF file was flagged by multiple heuristics as malicious, specifically for containing a link to a known malicious redirector. The ML classifier also assigned a high probability of maliciousness. The embedded URL http://botcraftman.ru/... is the primary indicator of malicious activity, likely serving as a lure for phishing or to download further 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.
