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

The PDF file contains a link to a known malicious redirector, http://botcraftman.ru/, which is a strong indicator of malicious intent. This type of link is commonly used to direct users to phishing pages or to download further malicious payloads. No scripts were extracted, and the document body was not available for analysis, limiting the ability to determine the exact nature of the threat beyond 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%B4%D0%B6%D0%B0%D1%81%D1%82%D0%B8%D0%BD+%D1%82%D0%B8%D0%BC%D0%B1%D0%B5%D1%80%D0%BB%D0%B5%D0%B9%D0%BA+%D0%BD%D0%BE%D0%B2%D1%8B%D0%B9+%D0%B0%D0%BB%D1%8C%D0%B1%D0%BE%D0%BC+2013+%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C&charset=utf-8
