Threat Intelligence Briefing

Global threat activity represents a significant deviation from the previous period, spiking by 45.4% to 3,348 events. This surge is primarily driven by increases in generic attacks, spam, and brute-force campaigns, particularly SSH bruteforce originating from a concentrated set of IPs in the US, Netherlands, and Brazil. Nordic activity remains largely stable and routine; Sweden saw 67 events consistent with its baseline, while Denmark, Finland, and Norway showed minimal, expected background noise. The top threat IPs are part of known, persistent SSH bruteforce campaigns. Given the global volume increase, focus on the pattern of SSH bruteforce from specific ASNs rather than ephemeral IPs. Consider implementing temporary rate-limiting rules for SSH traffic from concentrated geographic regions like the Netherlands and Brazil. No immediate action is required for Nordic-specific traffic, as it aligns with expected baselines.
