Threat Intelligence Briefing

Global threat volume increased by 11.2% compared to the previous 6-hour period, a notable but routine deviation consistent with typical daily fluctuations and the 7-day average. Reconnaissance remains the dominant activity category. Nordic countries show stable, low-volume activity; Sweden's 714 events primarily consist of attacks and brute force, which aligns with its established baseline, while Norway and Denmark exhibit minimal reconnaissance-only traffic. Defenders should prioritize monitoring and rate-limiting traffic from ASNs and CIDR ranges associated with Eastern European SSH brute force patterns, as evidenced by the top-attacker IPs from Romania and Bulgaria. Deprioritize individual IP addresses, as they are ephemeral. No immediate blocking is required for Nordic-originating traffic.
