T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a critical heuristic firing indicating a link to a known malicious redirector. The embedded URL, http://botcraftman.ru/, is likely part of a phishing or malware distribution chain. No scripts were extracted, and the document body was not sufficiently readable to determine a specific lure. The file's purpose is to redirect the user to malicious infrastructure.

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%BF%D1%80%D0%B0%D0%B2%D0%BA%D0%B0+windows+winhlp32exe+%D0%B4%D0%BB%D1%8F+windows+7&charset=utf-8
