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

The PDF file was identified as malicious due to an embedded link pointing to a known malicious redirector. This suggests the document is designed to lure users to a harmful website. No scripts were extracted, and the document body contained only metadata and image data, providing no further context on the specific lure. The primary IOC is the malicious URL.

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=%D1%80%D0%B0%D0%B1%D0%BE%D1%87%D0%B0%D1%8F+%D0%BF%D1%80%D0%BE%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%B0+%D0%BF%D0%BE+%D1%80%D0%BE%D0%B4%D0%BD%D0%BE%D0%BC%D1%83+%D1%80%D1%83%D1%81%D1%81%D0%BA%D0%BE%D0%BC%D1%83+%D1%8F%D0%B7%D1%8B%D0%BA%D1%83+7+%D0%BA%D0%BB%D0%B0%D1%81%D1%81+%D1%81%D0%B0%D1%8F%D1%85%D0%BE%D0%B2%D0%B0&charset=utf-8
