Threat Intelligence Briefing

Observed threat activity decreased 16% in the last 6 hours, dominated by SSH brute-force attacks globally. Compromised infrastructure remains largely datacenter-based. Limited Nordic activity was detected, with Sweden experiencing 3 brute-force attacks originating from 2 unique IPs. No specific hosting providers were disproportionately targeted. No significant Tor exit node activity was noted. Given the prevalence of Russian IPs involved in brute-force attempts, prioritize monitoring ASNs associated with the 45.135.0.0/16 and 45.140.0.0/16 ranges. Continue monitoring for SSH brute-force activity, and implement rate limiting on authentication attempts. Although HTTP DDoS attacks are low in volume, continue to monitor in case of an increase.
