Threat Intelligence Briefing

Global threat volume decreased by 8.9% compared to the previous period, consistent with routine daily fluctuations. Reconnaissance remains the dominant category. Nordic threat levels are stable and within expected baselines, with Sweden (619 events) and Finland (422) showing typical, high-volume background noise primarily from abuseipdb_blacklist and spam. The top threat IPs are concentrated within the 87.251.64.0/24 and 80.66.66.0/24 CIDR ranges, indicating coordinated SSH brute-force campaigns, not isolated events. These patterns are persistent and not a new development. Focus defensive efforts on monitoring and temporarily blocking these CIDR ranges associated with SSH brute-forcing. Deprioritize individual IP addresses from abuseipdb_blacklist categories, as they represent routine, lower-severity noise. Rate-limiting SSH connections from these networks is recommended.
