MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded link identified as a malicious redirector. The link, http://botcraftman.ru/..., is designed to lure users into clicking it by pretending to offer an adblocker download. This behavior is consistent with phishing or social engineering attacks aimed at directing users to malicious sites.

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.
