MITRE ATT&CK
T1566.002 Spearphishing Attachment T1200 Hardware Add-in Systems

The PDF file was flagged as a malicious redirector due to an embedded link pointing to botcraftman.ru. This infrastructure is known to be used for malicious purposes, likely to redirect users to phishing sites or download malware. No scripts were extracted, and the document body was not parsable, limiting further analysis of the specific lure.

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=%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B0+%D0%B4%D0%BB%D1%8F+%D0%B3%D0%BE%D0%BB%D0%BE%D1%81%D0%BE%D0%B2+%D0%B2%D0%BA%D0%BE%D0%BD%D1%82%D0%B0%D0%BA%D1%82%D0%B5&charset=utf-8
