The PDF file was flagged by multiple heuristics as malicious, specifically for containing a link to a known malicious redirector. The ML classifier also strongly indicated maliciousness. The embedded URL points to botcraftman.ru, which is identified as malicious infrastructure. The document body is heavily obfuscated and does not provide clear user-facing content, but the presence of the malicious link is the primary indicator of compromise.

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.
