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

The PDF file contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL 'http://botcraftman.ru/?lip&keyword=%D1%81%D0%BA%D0%B0%D1%87%D0%B0%D1%82%D1%8C+%D0%B8%D0%B3%D1%80%D1%83+%D0%BF%D0%B5%D1%80%D0%B5%D0%BF%D0%BE%D0%BB%D0%BE%D1%85+%D0%BD%D0%B0+%D1%80%D0%B0%D0%BD%D1%87%D0%BE+2&charset=utf-8' is the primary indicator of malicious intent. This suggests the document is designed to lure users to a malicious site, likely for phishing or malware distribution.

Heuristics 2

  • 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.
