Executive Summary
Global threat volume shows a significant deviation from baseline, spiking by 178% compared to the previous 6-hour period. This surge is primarily driven by a massive increase in low-reputation traffic and reconnaissance activity. The Nordic region remains relatively stable, with Sweden and Finland showing expected, routine volumes. The top threat actors are concentrated within specific CIDR ranges, notably a Polish ASN hosting multiple SSH brute-forcing IPs (87.251.64.144/29) and a Russian IP (<a href="https://ip.wayscloud.services/ip-intelligence/80.66.66.70" target="_blank">80.66.66.70</a>).
Given the coordinated SSH brute-force attacks from the Polish cluster, consider implementing temporary geo-blocking or rate-limiting for traffic originating from the relevant ASNs. Prioritize monitoring and blocking these CIDR ranges over individual IPs, as the infrastructure is persistent. Deprioritize the high-volume, low-reputation traffic as it represents background noise.
