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

The PDF contains a link to a known malicious redirector, http://botcraftman.ru/, which is indicative of a phishing or malware delivery attempt. The document body is heavily obfuscated and unreadable, providing no further context on the specific lure. No scripts were extracted from this sample.

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%82%D1%8B%D0%B6+%D0%BC%D0%B5%D0%BD%D1%8F+%D0%BF%D0%B8%D0%B4%D0%BC%D0%B0%D0%BD%D1%83%D0%BB%D0%B0+%D1%82%D0%B5%D0%BA%D1%81%D1%82+%D0%BF%D0%B5%D1%81%D0%BD%D0%B8&charset=utf-8
