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 highly suspicious and likely leads to a phishing or malware distribution site. No scripts were extracted, but the presence of this malicious link strongly suggests a social engineering attempt to lure the user to a compromised resource.

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.
