Threat Intelligence Briefing

Threat activity has surged, with total reports increasing by 28.5% compared to the previous 6-hour window. SSH brute-force attacks are overwhelmingly dominant, accounting for 98.6% of observed threats. Within the Nordic region, Sweden experienced limited activity consisting of a single SSH brute-force attack. Top attacking IPs are primarily located in Russia, Romania, and the Netherlands. We see no significant Tor exit node activity or specific ISP abuse patterns during this period. Given the spike in SSH brute-forcing, prioritize monitoring networks originating from RO, CN, and RU, particularly related to hosts on DigitalOcean (based on the top IPs). Implement stricter SSH access controls and consider geoblocking traffic from high-risk countries. Continue monitoring for changes in attack vectors and emerging threats targeting web applications, even though activity is currently low.
