Limited Nordic-specific activity was noted, with single SSH brute-force events originating from Finland and Sweden. No significant ISP or hosting provider abuse was detected. All observed attacks originated from datacenter IPs. Tactical Intelligence: Monitor ASNs associated with IPs 45.135.232.0/24 (Russia) and 185.156.73.0/24 (Ukraine) due to repeated SSH brute-force attempts. Track IP 196.251.87.194, exhibiting high activity as a botnet and malware C2. Defenders should prioritize detection and blocking rules for malware C2 traffic. Continue monitoring for increased SSH brute-force activity.
