Threat Intelligence Briefing

Threat activity is up 35.8% compared to the previous six-hour window, dominated by a focused SSH brute-force campaign originating primarily from Romanian and Russian IPs. No Nordic-specific activity was observed. Top attacking IPs, like 45.135.232.92 (RU), are consistently targeting SSH services. The absence of notable ISP/hosting provider abuse suggests a broad, distributed attack rather than concentrated activity within specific networks. No Tor exit node activity was detected within our monitored parameters. Given the concentrated SSH brute-force activity, prioritize monitoring networks exhibiting high volumes of failed SSH login attempts. Focus on ASNs associated with the identified Romanian and Russian IPs. Defenders should enforce strong password policies and consider implementing multi-factor authentication on SSH services. Continue tracking overall brute-force trends for potential shifts in target ports or protocols.
