MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document was flagged by multiple heuristics as malicious, specifically for containing a link to known malicious redirector infrastructure. The embedded URL `http://botcraftman.ru/...` is highly suspicious and likely serves as a lure to a phishing or malware distribution site. No scripts were extracted, and the document body was truncated, limiting further analysis of the exact payload.

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%9A%D0%B0%D0%BB%D1%8C%D0%BA%D1%83%D0%BB%D1%8F%D1%82%D0%BE%D1%80+%D0%BA%D0%BE%D0%B4%D0%BE%D0%B2+%D1%80%D0%B0%D0%B7%D0%B1%D0%BB%D0%BE%D0%BA%D0%B8%D1%80%D0%BE%D0%B2%D0%BA%D0%B8+%D0%BC%D0%B0%D0%B3%D0%BD%D0%B8%D1%82%D0%BE%D0%BB&charset=utf-8
