Threat Intelligence Briefing

The current threat landscape shows a marginal decrease of 0.5% in total threats compared to the previous six-hour window, with a dominant focus on SSH brute-force attempts (98.5%). Attacks are sourced primarily from residential IPs in the US, China, South Korea, and Russia. No significant activity was observed originating from or targeting Nordic countries during this period. No specific ISP or hosting provider emerged as a disproportionate source or target of malicious activity. No Tor exit node abuse was observed. Given the persistent SSH brute-force activity, defenders should prioritize hardening SSH configurations and implementing multi-factor authentication. Monitor ASNs associated with the top attacking countries, particularly those exhibiting spikes in failed SSH login attempts. Track the IPs 62.60.131.157, 45.134.26.79, 45.135.232.177, 45.140.17.124, and 2.57.121.112 as they are the most active attackers.
