Threat Intelligence Briefing

Global threat activity changed by several orders of magnitude (1,337 → 1,657,952 events), primarily driven by malware C2 traffic (1,656,489 events). This represents a significant deviation from typical behavior, with US, NL, and CN as top origin countries. Nordic regions show stable low-volume activity, with Sweden (10 events) and Finland (4 events) reporting attacks and SSH brute-force attempts. Norway recorded a single tor_exit node event. Given the scale of malware C2 traffic, this likely reflects a widespread campaign rather than isolated incidents. Consider temporarily rate-limiting traffic from ASNs associated with malware C2 infrastructure, particularly those in the US and NL. Prioritize investigation of SSH brute-force clusters from NL (<a href="https://ip.wayscloud.services/ip-intelligence/167.172.37.12" target="_blank">167.172.37.12</a>) and RU (<a href="https://ip.wayscloud.services/ip-intelligence/45.135.232.92" target="_blank">45.135.232.92</a>) IP ranges. Deprioritize low-volume Nordic events unless they match known attack patterns.
