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 lead to malicious content. The document body is heavily truncated and does not provide further context. No scripts were extracted from this sample. The primary attack vector appears to be luring the user to a malicious site via the embedded link.

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=swat+4+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D1%82%D0%BE%D1%80%D1%80%D0%B5%D0%BD%D1%82+%D0%BD%D0%B0+%D1%80%D1%83%D1%81%D1%81%D0%BA%D0%BE%D0%BC+%D1%8F%D0%B7%D1%8B%D0%BA%D0%B5&charset=utf-8
