MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a critical heuristic firing indicating a link to known malicious redirector infrastructure. The embedded URL, http://botcraftman.ru/?lip&keyword=Admin+hack+v6+0&charset=utf-8, is the primary indicator of malicious intent. While no scripts were explicitly extracted, the PDF structure and the malicious link suggest an attempt to lure the user to a compromised site, likely for further exploitation or credential harvesting.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • 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.
