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

The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL 'http://botcraftman.ru/...' is flagged as malicious. This suggests the document's primary purpose is to redirect the user to a harmful site, likely for phishing or malware delivery. No scripts were extracted, and the document body was not sufficiently readable to provide further context.

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%BC%D0%B0%D0%BA%D0%B0%D1%80%D1%8B%D1%87%D0%B5%D0%B2+%D1%8E+%D0%BD+%D0%B0%D0%BB%D0%B3%D0%B5%D0%B1%D1%80%D0%B0+10+%D0%BA%D0%BB%D0%B0%D1%81%D1%81&charset=utf-8
