Threat Intelligence Briefing

Observed global threat activity decreased by 2% in the last 6 hours, with brute-force attacks against SSH services dominating (95% of all reported events). Activity originating from Russia, China, and Singapore accounted for approximately 29% of global attacks. Limited Nordic-specific activity was seen, with only two brute-force attacks against SSH services originating from a single IP address in Norway. There were no statistically significant infrastructure patterns or Tor exit node abuse during this period. Monitor the 45.135.232.0/24 and 45.140.17.0/24 Russian-based networks for continued brute-force attempts. Investigate traffic originating from 159.223.208.147 (Netherlands) and 134.199.160.8 (Australia) for potential compromised hosts. Due to the high prevalence of SSH brute-force attacks, ensure all SSH services have strong, unique passwords and consider implementing multi-factor authentication.
