Threat Intelligence Briefing

Global threat activity increased by 78.4% compared to the previous 6-hour period, with malware C2 communications (734 events) and attacks (456 events) dominating. The Netherlands (363 events) and the US (242 events) remain primary sources, while Nordic countries show minimal activity (Sweden: 3 events). A cluster of Russian IPs (<a href="https://ip.wayscloud.services/ip-intelligence/176.120.22.0" target="_blank">176.120.22.0</a>/24) exhibited repeated SSH brute-force attempts, consistent with known botnet behavior. This surge aligns with historical post-maintenance attack patterns observed on weekdays. Consider temporary rate-limiting for SSH traffic from ASNs associated with the Russian and Bulgarian IP clusters, particularly during peak activity windows. Deprioritize individual IP blocking for low-volume Nordic events, as these represent routine scanning.
