MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file was flagged by multiple heuristics as malicious, specifically for containing a link to known malicious redirector infrastructure. The embedded URL 'http://botcraftman.ru/...' is highly suspicious and likely serves as a lure to a phishing or malware distribution site. No scripts were extracted, but the presence of a malicious link strongly suggests an intent to redirect the user to a harmful destination.

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.
    URL http://botcraftman.ru/?lip&keyword=%D1%81%D1%82%D0%B5%D0%BA%D0%BB%D1%8F%D0%BD%D0%BD%D1%8B%D0%B9+%D1%82%D1%80%D0%BE%D0%BD+%D1%81%D0%B0%D1%80%D0%B0+%D0%B4%D0%B6+%D0%BC%D0%B0%D0%B0%D1%81+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C&charset=utf-8
