The PDF file was flagged by a machine learning classifier and contains a link to a known malicious redirector infrastructure. The embedded URL points to 'botcraftman.ru', which is associated with malicious redirector activity. The document body is heavily obfuscated and does not provide clear textual clues about its intent, but the presence of the malicious link strongly suggests a phishing or malware delivery attempt.

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.
