Threat Intelligence Briefing

Global threat volume increased by 3.0% compared to the previous period, remaining consistent with the 7-day average and representing routine background noise. The majority of activity (91.6%) was reconnaissance. Nordic countries showed stable, baseline-consistent threat levels, with Sweden (654 events) and Finland (359 events) leading the region in typical scanning and brute-force activity. A cluster of SSH brute-force attacks originating from Polish IPs in the 87.251.64.144/29 range was notable but aligns with known, persistent threat actor infrastructure patterns. Defenders should prioritize monitoring and potential rate-limiting for the persistent Polish SSH brute-force cluster (ASN 5617) rather than individual IPs. Continue to deprioritize the high-volume global reconnaissance traffic as routine background noise unless targeting specific, high-value Nordic assets.
