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

The PDF file was identified as malicious due to a critical heuristic firing for a link to known malicious redirector infrastructure. The embedded URL, http://botcraftman.ru/, is the primary indicator of malicious intent. No scripts were extracted from this sample, and the document body was truncated, limiting further analysis of the specific lure. The file's purpose is likely to redirect users to a malicious website for phishing or malware delivery.

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%9B%D0%B0%D0%B1%D0%BE%D1%80%D0%B0%D1%82%D0%BE%D1%80%D0%BD%D0%B0%D1%8F+%D1%80%D0%B0%D0%B1%D0%BE%D1%82%D0%B0+%D0%BF%D0%BE+%D1%84%D0%B8%D0%B7%D0%B8%D0%BA%D0%B5+7+%D0%BA%D0%BB%D0%B0%D1%81%D1%81+%D0%B0%D1%81%D1%82%D0%B0%D1%85%D0%BE%D0%B2%D0%B0+%D0%BE%D1%82%D0%B2%D0%B5%D1%82%D1%8B&charset=utf-8
