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

The PDF file was identified as malicious due to a critical heuristic firing for a link to a known malicious redirector. The embedded URL http://botcraftman.ru/... is highly suspicious and likely serves as a gateway to a malicious destination. No scripts were extracted, and the document body was truncated, limiting further analysis of the specific lure. The file's purpose is inferred to be redirection to a harmful site.

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%BE%D0%B2%D1%80%D0%B5%D0%BC%D0%B5%D0%BD%D0%BD%D1%8B%D0%B9+%D1%83%D1%80%D0%BE%D0%BA+%D0%BD%D0%B5%D0%BC%D0%B5%D1%86%D0%BA%D0%BE%D0%B3%D0%BE+%D1%8F%D0%B7%D1%8B%D0%BA%D0%B0+%D0%BF%D0%BE+%D1%84%D0%B3%D0%BE%D1%81&charset=utf-8
