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

The PDF file was flagged as a malicious redirector due to the presence of a link to botcraftman.ru. This URL is known to lead to malicious infrastructure. The document body appears to be malformed or truncated, preventing a deeper analysis of its content. No scripts were extracted from this sample. The primary threat is the malicious link, which is likely intended to lure the user to a site for phishing or malware delivery.

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%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B4%D1%80%D0%B0%D0%B9%D0%B2%D0%B5%D1%80%D0%B0+%D0%B4%D0%BB%D1%8F+%D0%BF%D1%80%D0%B8%D0%BD%D1%82%D0%B5%D1%80%D0%B0+oki+b2200&charset=utf-8
