Threat Intelligence Briefing

Observed threat activity decreased significantly, down 63% compared to the previous 6-hour window. SSH bruteforce attempts remain the dominant threat vector globally, comprising 96% of all observed attacks. Within the Nordic region, Sweden saw 3 unique IPs involved in SSH bruteforce activity, while Denmark recorded a single IP. No specific hosting providers or ISPs stand out, and there is no notable Tor exit node activity. Attackers primarily target datacenter IPs, although no specific infrastructure patterns were identified. Given the continued prevalence of SSH bruteforce attacks, we recommend defenders prioritize hardening SSH configurations and monitoring authentication logs. Focus monitoring on ASNs originating from Russia, Romania, and China due to their high concentration of malicious activity. While overall threat volume is down, the consistency of SSH bruteforce necessitates continued vigilance.
