Threat Intelligence Briefing

Global threat volume decreased significantly by 64.1% compared to the previous 6-hour period, representing a major deviation from the elevated baseline. This sharp decline is atypical and suggests a potential shift in attacker operations or a temporary lull. Nordic traffic remained stable and routine; Sweden (28 events) and Finland (15 events) showed consistent patterns with their recent averages, while Norway's minimal activity (2 events) is normal. The top threat categories—attacks, brute force, and spam—remained consistent despite the overall volume drop. Focus remains on SSH brute force attacks originating from IPs in Russia, Romania, and the US. Given the significant volume decrease, maintain standard defensive postures but prioritize monitoring for a potential resurgence. Continue to rate-limit SSH traffic, particularly from ASNs frequently hosting brute force activity. This period of low activity should be used to review and validate existing blocklists against the persistent SSH brute force clusters identified.
