Threat Intelligence Briefing

Global threat volume decreased significantly by 63% compared to the previous 6-hour period, with 104,526 events consistent with typical overnight traffic patterns. Nordic countries remained stable; Sweden (723 events) and Finland (406) showed routine reconnaissance and blacklist activity, while Norway (209) and Denmark (74) maintained baseline levels. The top threat categories shifted from attacks to reconnaissance, which comprised 97% of all activity, indicating a return to normal scanning operations after an anomalous spike. Focus monitoring on reconnaissance patterns from ASNs in Romania and Bulgaria, as these were the primary sources for SSH brute force attacks. Deprioritize individual IP blocking given the high volume of unique addresses. Consider temporary rate-limiting for SSH traffic from Eastern European networks if aligned with business hours.
