MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file was flagged as a malicious redirector due to the presence of a link to botcraftman.ru. This URL is known to point to malicious infrastructure, suggesting the document's purpose is to lure users to a harmful website. No scripts were extracted, and the document body was not parsable text, so the attack pattern is inferred solely from the malicious URL.

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%B1%D0%B5%D1%81%D1%82+%D1%85%D0%B0%D0%BA+%D0%BC%D0%B0%D0%B3%D0%BD%D0%B8%D1%82+%D0%BD%D0%B0+%D0%B2%D0%B0%D1%80%D1%84%D0%B5%D0%B9%D1%81&charset=utf-8
