Threat Intelligence Briefing

Global threat volume increased by 8.1% compared to the previous 6-hour period, representing a moderate but notable deviation from the recent baseline. This rise is primarily driven by malware C2 activity (1063 events) and attack traffic (752 events), with SSH brute force remaining a significant component. Nordic activity remains minimal and routine; Finland and Sweden show low, stable counts consistent with their historical patterns. The top threat actors are concentrated in ASNs from the US, Australia, and Singapore, indicating a continuation of established global attack patterns rather than a new campaign. Focus on the persistent SSH brute force clusters from Dutch (ASN 20473) and Singaporean networks, as these represent the most consistent infrastructure. Consider implementing temporary rate-limiting rules for SSH traffic originating from these specific ASN ranges to mitigate the high-volume, automated attempts. Deprioritize individual IP addresses from the top list as they are likely ephemeral, but maintain vigilance on the broader network blocks they operate within.
