Threat Intelligence Briefing

Global threat activity represents a significant deviation from the previous period, with a 47.6% increase to 4,732 events. This surge is primarily driven by malware C2 (1,447) and attack (1,120) traffic, consistent with a widespread campaign rather than routine background noise. Nordic activity remains comparatively low, with Sweden (20 events) and Finland (5 events) showing patterns consistent with their typical baseline for SSH brute-forcing and botnet-related probes. The top threat actors are concentrated in ASNs from the US, India, and Singapore. Consider implementing temporary rate-limiting rules targeting SSH traffic from CIDR ranges associated with the top-source countries and ASNs, particularly for ports 22 and 23. This proactive measure will mitigate the increased volume of automated attacks without impacting legitimate traffic.
