Executive Summary
Global threat volume changed by several orders of magnitude (3,385 → 24,585 events), representing a significant deviation from the previous period. This surge is primarily driven by attacks, spam, and brute-force activity originating from the US, Singapore, and Germany. Nordic countries remain stable at low baselines; Sweden (86 events) and Finland (41 events) show typical background noise patterns, primarily scanning and brute-force attempts. This global spike is not a new campaign but a sharp, widespread increase in routine malicious activity. Focus on the patterns, not the individual IPs, which are ephemeral.
Given the surge, prioritize reviewing and hardening external-facing services like SSH. Consider temporarily rate-limiting traffic from ASNs in the top-source countries, particularly for brute-force and attack patterns. The Nordic-specific activity does not warrant immediate action beyond standard monitoring, as it aligns with historical baseline levels.
