Threat Intelligence Briefing

Threat volume decreased by 30.1% compared to the previous period, representing a return to routine baseline levels after heightened activity. Malware C2 remains the dominant category globally. Nordic regions show stable, low-level activity consistent with their typical background noise, primarily comprising brute-force and attack traffic. The top threat actors are concentrated within specific ASNs known for hosting malicious infrastructure, particularly in Russia (<a href="https://ip.wayscloud.services/asn-intelligence/12389" target="_blank">AS12389</a>, ASN for <a href="https://ip.wayscloud.services/ip-intelligence/80.66.66.70" target="_blank">80.66.66.70</a>) and Romania, focusing heavily on SSH brute-force attacks. This pattern is not new but a persistent feature of the threat landscape. Focus defensive actions on the broader CIDR ranges associated with these high-volume SSH brute-force ASNs rather than individual, ephemeral IPs. Consider implementing temporary rate-limiting rules for SSH traffic originating from these networks. Deprioritize individual alerts from these sources as they are part of a known, persistent campaign and represent routine background noise.
