MITRE ATT&CK

T1059.001 PowerShell

The PDF contains an embedded link to a known malicious redirector. This indicates the file's primary purpose is to lure users to a potentially harmful website. The link `http://botcraftman.ru/?lip&keyword=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B8%D0%B3%D1%80%D1%83+%D0%BD%D0%B0+%D0%BF%D0%BB%D0%B0%D0%BD%D1%88%D0%B5%D1%82+%D1%80%D0%B0%D1%81%D1%82%D0%B5%D0%BD%D0%B8%D1%8F+%D0%BF%D1%80%D0%BE%D1%82%D0%B8%D0%B2+%D0%B7%D0%BE%D0%BC%D0%B1%D0%B8&charset=utf-8` is flagged as malicious. No scripts were extracted, and the document body was unreadable, 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=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B8%D0%B3%D1%80%D1%83+%D0%BD%D0%B0+%D0%BF%D0%BB%D0%B0%D0%BD%D1%88%D0%B5%D1%82+%D1%80%D0%B0%D1%81%D1%82%D0%B5%D0%BD%D0%B8%D1%8F+%D0%BF%D1%80%D0%BE%D1%82%D0%B8%D0%B2+%D0%B7%D0%BE%D0%BC%D0%B1%D0%B8&charset=utf-8
