Threat Intelligence Briefing

Global threat volume decreased by 65.2% compared to the previous period, representing a significant deviation from the elevated baseline. This decline suggests a possible end to a coordinated campaign rather than routine background noise. Nordic countries show stable, low-level activity consistent with their 7-day averages, with Sweden (725 events) and Finland (418 events) leading regional traffic. The most notable activity cluster originates from Vietnamese IPs (171.231.0.0/16 range) conducting SSH brute force attacks, a pattern active for several weeks. Consider temporarily blocking the 171.231.0.0/16 CIDR range and implementing SSH rate-limiting policies, particularly for internet-facing systems. Deprioritize individual Romanian IPs (2.57.121.0/24) as they represent routine, low-volume noise.
