Threat Intelligence Briefing

Global threat volume decreased by 91.8% compared to the previous period, a significant deviation from the high baseline. This sharp decline is unusual and may indicate a temporary lull in coordinated activity rather than a genuine reduction in threat. SSH brute-force attacks remain the dominant category. Nordic regions (FI, SE) show minimal activity, with only 5 events each, which is consistent with their typical low-volume baseline and represents routine background scanning rather than targeted campaigns. The top threat IPs originate primarily from ASNs in the Netherlands, Russia, and Romania. Focus on the persistent SSH brute-force pattern from these network blocks rather than individual, ephemeral IP addresses. Consider implementing temporary rate-limiting rules for SSH traffic originating from known problematic ASNs in these regions to mitigate the most common attack vector without impacting legitimate business traffic.
