MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file was flagged by a critical heuristic for linking to known malicious redirector infrastructure. The ML classifier also assigned a high probability of maliciousness. The embedded URL, http://botcraftcraftman.ru/..., is the primary indicator of malicious intent, likely serving as a lure to a phishing or malware distribution site. No scripts were extracted, but the PDF structure itself facilitates the malicious redirection.

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.
