MITRE ATT&CK

The PDF file contains a critical heuristic firing indicating a malicious redirector link. This link points to botcraftman.ru, which is known for malicious activity. The document body is truncated and does not provide further context, but the presence of the malicious URL is sufficient to classify the attack pattern. No scripts were extracted from this sample.

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.
