MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.001 User Execution: Malicious Link

The PDF file was flagged by a machine learning classifier and contains a critical heuristic indicating a link to known malicious redirector infrastructure. The embedded URL 'http://botcraftman.ru/?lip&keyword=%D1%87%D0%B8%D1%82%D1%8B+%D0%B2+%D1%82%D0%B0%D0%BD%D0%BA%D0%B0%D1%85+%D0%BE%D0%BD%D0%BB%D0%B0%D0%B9%D0%BD&charset=utf-8' is the primary indicator of malicious intent. This suggests the document is designed to lure users to a harmful website.

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.
