MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains an embedded link identified as a malicious redirector. This heuristic indicates the document is designed to lure users to a potentially harmful website. The link http://botcraftman.ru/... is flagged as malicious. 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=%D0%BF%D1%80%D0%BE%D1%85%D0%BE%D0%B4%D0%BD%D0%BE%D0%B9+%D0%B1%D0%B0%D0%BB%D0%BB+%D0%B3%D0%B8%D0%B0+%D0%BF%D0%BE+%D1%80%D1%83%D1%81%D1%81%D0%BA%D0%BE%D0%BC%D1%83+%D1%8F%D0%B7%D1%8B%D0%BA%D1%83+2015&charset=utf-8
