MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.001 Malicious Link

The PDF file contains a critical heuristic firing indicating a link to a known malicious redirector. This suggests the document is designed to lure users to a malicious website. The primary IOC is the malicious redirector URL itself, which is likely the first step in a phishing or malware delivery chain.

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%92%D1%81%D0%BA%D1%80%D1%8B%D1%82%D0%B8%D0%B5+%D1%82%D1%80%D1%83%D0%BF%D0%B0+%D0%B4%D0%B5%D0%B2%D1%83%D1%88%D0%BA%D0%B8+%D0%B2+%D0%BC%D0%BE%D1%80%D0%B3%D0%B5&charset=utf-8
