Threat Intelligence Briefing

Threat volume remains stable, decreasing slightly by 2.2% compared to the previous 6-hour period, consistent with the 7-day average. The Netherlands (ASN 20473, 204867) remains the top source country, primarily for malware C2 traffic. SSH brute force activity persists as the dominant attack pattern, with notable clusters from Russian (<a href="https://ip.wayscloud.services/ip-intelligence/176.120.22.0" target="_blank">176.120.22.0</a>/24) and Romanian (<a href="https://ip.wayscloud.services/ip-intelligence/2.57.122.0" target="_blank">2.57.122.0</a>/24) networks. Nordic activity is routine, with Sweden showing typical background noise across multiple attack types. No new campaigns emerged; this is routine global scanning and opportunistic attacks. Consider implementing temporary rate-limiting on SSH services, particularly for traffic originating from the identified Eastern European CIDR blocks. Prioritize investigation of any successful authentication attempts linked to these brute force clusters. Deprioritize individual IPs from the Netherlands, as this represents high-volume, ephemeral C2 infrastructure.
