Threat Intelligence Briefing

Threat volume decreased by 92.5% versus the previous period, representing a significant deviation from the typical high-volume baseline. This sharp reduction is unusual and suggests a potential lull or shift in adversary infrastructure. SSH brute force activity remains the dominant attack category. Nordic regions show minimal activity, with Sweden's 8 events and Finland's single SSH brute force attempt being routine and consistent with their typical low baselines. The top threat IPs, primarily from NL, RO, and RU, are part of known SSH brute force campaigns. Focus on clusters, not individual ephemeral IPs. Consider temporarily blocking or rate-limiting traffic from known malicious ASNs and CIDR ranges associated with persistent SSH brute force campaigns, particularly those originating from the Netherlands and Eastern Europe. Deprioritize individual IP responses unless part of a sustained pattern.
