MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a link to a known malicious redirector, botcraftman.ru, which is highly indicative of a phishing or malware distribution attempt. The ML classifier also flagged this PDF with high confidence. While no scripts were explicitly extracted, the presence of a malicious URL within the document body strongly suggests an attempt to lure the user to a compromised site.

Heuristics 2

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • Embedded URL info EMBEDDED_URL
