Threat Intelligence Briefing

Threat activity has significantly decreased, down 89.5% compared to the previous six-hour window. The vast majority (92%) of observed global threats are SSH brute-force attempts, with a smaller fraction targeting general brute-force (6%). Romania and Russia are the top originating countries, accounting for 44% of all attacks. No significant Nordic-specific activity was observed. Top attacking IPs are primarily located in Russia. No infrastructure patterns or notable ISP/hosting provider abuse was detected during this period. Tor exit node usage remains insignificant. Given the concentration of SSH brute-force activity, prioritize monitoring networks originating from Russia and Romania. Continue to monitor for shifts in attack vectors, particularly the emergence of CMS attacks or spam campaigns. Ensure SSH services are hardened with strong passwords and multi-factor authentication. While overall activity is down, vigilance remains crucial to detect potential pivots in attacker behavior.
