Threat Intelligence Briefing

Global threat volume represents a significant deviation, spiking by over 300% compared to the previous 6-hour period. This surge is consistent with a broad increase across all major categories, particularly spam and malware C2. Nordic countries show proportional increases, with Sweden (64 events) and Finland (52) leading regional activity. This is not routine; the volume is substantially above the 7-day average and indicates a coordinated uptick in malicious infrastructure activation. The top threat IPs are concentrated in SSH brute-forcing and web attacks, originating from diverse geographic locations. Focus on the pattern of brute-force attacks from ASNs in the US, RU, and VN rather than individual IPs, as the infrastructure is highly ephemeral. Consider implementing temporary, aggressive rate-limiting on SSH and web administrative interfaces, particularly for services exposed to the public internet. Deprioritize individual IP blocking in favor of geo-fencing for regions with high malicious traffic density if consistent with business needs.
