Threat Intelligence Briefing

Global threat volume changed by several orders of magnitude (1,582 → 16,310 events), representing a severe deviation from the previous 6-hour baseline. This surge is primarily driven by spam and attack categories, with notable activity from US, CN, and NL-based IPs. Nordic region volumes remain stable and consistent with their 7-day averages, with Finland and Sweden showing the highest but routine activity, primarily brute-force and attack traffic. The top threat IPs are overwhelmingly concentrated in SSH brute-force campaigns from specific Eastern European ASNs. Focus defensive actions on the observed SSH brute-force pattern from CIDR ranges in Russia, Netherlands, and Bulgaria rather than individual IPs. Consider implementing temporary rate-limiting on SSH services and reviewing authentication logs for these source networks. Deprioritize the low-volume Nordic activity, which is consistent with routine background noise.
