Threat Intelligence Briefing

Global threat activity spiked by 437% compared to the previous 6-hour period, representing a significant deviation from typical baseline traffic. This surge is primarily driven by brute-force and SSH attacks originating from IPs in the US, Netherlands, and China. Nordic countries show stable, routine activity levels consistent with their historical baselines, with Finland (77 events) and Sweden (56 events) seeing the most traffic, predominantly in attacks and brute-force categories. The top threat IPs are clustered around SSH brute-forcing from Russian and Bulgarian ASNs. Focus defensive actions on the observed SSH brute-force campaign patterns rather than individual IPs. Consider implementing temporary rate-limiting on SSH services and geo-blocking traffic from high-volume regions like ASNs in Russia and Bulgaria if not required for business operations. Routine Nordic activity does not warrant immediate action beyond normal monitoring.
