MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document was flagged by multiple heuristics as malicious, specifically for containing a link to a known malicious redirector. 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 a malicious link strongly suggests an attempt to lure the user to a harmful destination.

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%B4%D0%BD%D0%B5%D0%B2%D0%BD%D0%B8%D0%BA+%D0%B1%D1%83%D0%B4%D1%83%D1%89%D0%B5%D0%B3%D0%BE+%D1%85%D0%B5%D0%BD%D1%82%D0%B0%D0%B9&charset=utf-8
