Threat Intelligence Briefing

Global threat volume changed by several orders of magnitude (4,230 → 27,962 events), representing a significant deviation from the previous baseline. This surge is primarily driven by attacks, spam, and brute-force campaigns originating from the US, India, and Germany. Nordic region traffic remains routine and stable, with Sweden (79 events) and Finland (54 events) showing typical background noise levels consistent with their 7-day averages. The top threat IPs are predominantly SSH brute-forcers, a common but high-volume tactic. Focus on the pattern of SSH brute-force attempts from the /16 CIDRs of the top offending ASNs rather than individual ephemeral IPs. Consider implementing temporary rate-limiting rules for SSH traffic from these network blocks to mitigate the increased global volume without impacting legitimate business operations.
