Threat Intelligence Briefing

Global threat volume decreased significantly by 86.5% compared to the previous period, representing a major deviation from the high-volume baseline. This sharp decline suggests the conclusion of a major campaign rather than routine noise. Nordic activity remains minimal and stable, with Sweden showing the highest volume at 27 events, consistent with its typical low-level background activity. The primary threats are SSH brute-force attacks, with a notable cluster originating from Russian IPs (<a href="https://ip.wayscloud.services/ip-intelligence/176.120.22.0" target="_blank">176.120.22.0</a>/24 range) and Bulgarian infrastructure. Focus defensive actions on monitoring and potentially rate-limiting SSH traffic from Eastern European ASNs, particularly those hosting the identified Russian and Bulgarian IP clusters. The significant global decrease allows teams to deprioritize broad threat hunting and concentrate on hardening SSH access points against these persistent, targeted brute-force attempts.
