Threat Intelligence Briefing

Global threat volume increased by 4.2% compared to the previous period, consistent with the 7-day average and representing routine background noise. Nordic countries remained stable; Sweden (634 events) and Finland (406 events) saw typical reconnaissance and attack patterns. A notable cluster of SSH brute-force activity originated from a Polish ISP (<a href="https://ip.wayscloud.services/asn-intelligence/5617" target="_blank">AS5617</a>, 87.251.64.0/24) and Vietnamese addresses, though this is a persistent campaign active for weeks. Focus on the Polish CIDR block and Vietnamese IP ranges rather than individual addresses. Consider temporary blocking or rate-limiting SSH traffic from these specific ASNs, as the IPs themselves are ephemeral. Deprioritize the global reconnaissance noise, which remains within expected parameters.
