Threat Intelligence Briefing

Global threat volume decreased by 29.4% compared to the previous 6-hour period, representing a significant deviation from the recent elevated baseline and returning to levels consistent with the 7-day average. SSH brute force attacks remain the dominant threat category, with notable clustering from Russian (<a href="https://ip.wayscloud.services/asn-intelligence/12389" target="_blank">AS12389</a>, Rostelecom) and Bulgarian (<a href="https://ip.wayscloud.services/asn-intelligence/8866" target="_blank">AS8866</a>, Megalan) networks. Nordic activity remains routine, with Finland showing the highest but expected volume of automated attacks and brute force attempts across its infrastructure. The observed reduction suggests a potential shift in adversary infrastructure or temporary operational pauses. Focus should remain on the persistent threat pattern rather than the temporary volume decrease. Prioritize monitoring and hardening of SSH services, particularly against the identified high-volume ASN clusters originating from Eastern Europe. Consider implementing temporary geo-blocking or rate-limiting rules for traffic from <a href="https://ip.wayscloud.services/asn-intelligence/12389" target="_blank">AS12389</a> and <a href="https://ip.wayscloud.services/asn-intelligence/8866" target="_blank">AS8866</a> if these patterns persist, as individual IPs within these networks are frequently replaced. Deprioritize investigation of the overall volume reduction, as this appears to be a normalization of background noise.
