Threat Intelligence Briefing

Global threat volume decreased significantly, with a 39.5% reduction compared to the previous 6-hour period, now at 1,858 events. This decline is a notable deviation from the higher activity levels observed recently. SSH brute-force attacks remain the dominant category, with a cluster of IPs from Russia (<a href="https://ip.wayscloud.services/asn-intelligence/12389" target="_blank">AS12389</a>, <a href="https://ip.wayscloud.services/ip-intelligence/176.120.22.0" target="_blank">176.120.22.0</a>/24) and Bulgaria being particularly active. Nordic regions are stable; Sweden's 15 events are consistent with its 7-day average, primarily consisting of routine background scanning and attack probes. The Netherlands (<a href="https://ip.wayscloud.services/asn-intelligence/20473" target="_blank">AS20473</a>) continues to be the top source country. Defender actions should prioritize monitoring the persistent Russian and Bulgarian SSH brute-force clusters, as these represent a concentrated threat. Consider temporary blocking or rate-limiting the /24 CIDR ranges associated with these campaigns. The overall decrease in volume allows teams to deprioritize mass IP blocking and focus on these specific, high-yield patterns.
