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

The PDF file contains a direct link to a known malicious redirector, http://botcraftman.ru/. This heuristic firing indicates the document is designed to redirect users to potentially harmful content. No scripts were extracted, and the document body was not sufficiently readable to provide further context on the lure. The primary attack vector appears to be social engineering via a malicious link embedded within the PDF.

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.
