Threat Intelligence Briefing

Global threat volume shows a significant deviation from baseline, increasing by 175.8% compared to the previous 6-hour period. This surge is primarily driven by reputation_low and reconnaissance activity, with the US, China, and Germany remaining top source countries. Nordic countries, particularly Sweden and Finland, show elevated but routine threat levels consistent with their recent 7-day averages, primarily comprising reconnaissance and brute-force attacks. The top threat IPs are predominantly SSH bruteforce sources from Polish and Russian networks, forming a clear attack cluster. This global spike represents a notable escalation in background noise rather than a targeted campaign. Focus defensive actions on the identified SSH bruteforce cluster from Polish ASNs (87.251.64.0/24 range) rather than individual IPs. Consider implementing temporary rate-limiting on SSH ports for all external-facing systems. Deprioritize individual low-reputation IPs from the US and China, as these represent routine scanning activity and are not a deviation from normal baseline traffic patterns.
