Threat Intelligence Briefing

Global threat volume decreased by 63% compared to the previous 6-hour period, a significant but routine drop consistent with normal diurnal patterns and weekend traffic fluctuations. Reconnaissance remains the dominant category (85,522 events). Nordic threat levels remain stable relative to their 7-day baselines, with Sweden (660 events) and Finland (416) showing expected patterns of abuseipdb_blacklist, attacks, and brute_force activity. The top threat IPs are clustered within specific CIDR ranges from Poland (87.251.64.0/24) and Russia, focusing on SSH brute-forcing, indicating coordinated scanning rather than targeted attacks. Given the routine nature of this activity, no immediate defensive changes are required. Continue to monitor for deviations from these stable baselines. For the observed SSH brute-force clusters, consider maintaining existing rate-limiting rules on port 22 targeting the /24 CIDR blocks from Eastern European networks, as these IPs are ephemeral within known malicious ranges.
