Threat Intelligence Briefing

Observed global threat activity indicates a 34% surge in malicious events compared to the prior six-hour window, primarily driven by SSH brute-force attacks. Datacenter infrastructure continues to be the main origin of attacks. Within the Nordic region, limited activity was detected, with single SSH brute-force events originating from unique IPs in Finland, Norway, and Sweden. No significant abuse of specific hosting providers was observed. No Tor exit node activity was detected during this period. Given the intensification of brute-force attacks, monitor ASNs associated with top attacking IPs, particularly those originating from Russia. Focus on hardening SSH access controls and consider implementing multi-factor authentication. Track emerging brute-force techniques targeting other services beyond SSH, as the overall brute-force category also increased.
