Threat Intelligence Briefing

Global threat volume has decreased significantly, with a 90.3% reduction compared to the previous 6-hour period. This sharp decline represents a major deviation from the extremely high baseline, suggesting the conclusion of a large-scale, short-lived campaign. Nordic activity remains low and routine; Sweden (9 events) and Finland (8 events) show typical background noise primarily consisting of SSH brute force and web attacks. The top threat IPs, originating from Bulgaria, Romania, and the US, are focused almost exclusively on SSH brute force, a persistent but manageable threat. Focus on patterns over individual IPs. The observed SSH brute force clusters from specific ASNs in Eastern Europe and the US warrant attention. Consider implementing temporary rate-limiting rules for SSH traffic originating from these high-risk regions to mitigate this routine but persistent threat vector, while deprioritizing individual IP blocks due to their ephemeral nature.
