Threat Intelligence Briefing

Global threat volume represents a significant deviation from baseline, spiking by 163.5% compared to the previous period to 4,788 events. This surge is primarily driven by attacks and spam categories. The Nordic region remains relatively stable, with Finland and Sweden showing the highest but routine activity levels. Notably, a cluster of SSH brute force attacks originated from a small set of IPs in Russia (<a href="https://ip.wayscloud.services/asn-intelligence/12389" target="_blank">AS12389</a>/Rostelecom) and Bulgaria, indicating a coordinated campaign rather than random noise. This pattern is a clear escalation from recent background activity. Focus defensive actions on the identified SSH brute force clusters from Eastern European ASNs. Consider implementing temporary geo-blocking or rate-limiting rules targeting high-risk networks, particularly for port 22. Prioritize monitoring these patterns over individual IPs, as the attack infrastructure is likely to shift. Deprioritize the low-volume spam traffic from Denmark, which is consistent with routine background noise.
