Threat Intelligence Briefing
Analysis period: 2026-04-06T18:00:01.923688 - 2026-04-07T00:00:01.923688 (6 hours)
Executive Summary
Threat volume decreased significantly by 58.6% compared to the previous period, falling to 1602 total events. This represents a substantial deviation from the elevated baseline, though activity remains consistent with routine background noise patterns. SSH brute-force attacks dominated the threat landscape, primarily originating from US and Romanian IPs. Nordic countries showed minimal activity, with Sweden (7 events) and Finland (6 events) experiencing routine low-level brute-force and spam attempts, while Norway recorded only 2 botnet-related events. Focus on SSH-related traffic patterns rather than individual IPs, as the top threats are distributed across multiple countries and ASNs. Consider implementing temporary rate-limiting measures against SSH connection attempts from suspicious CIDR blocks, particularly those originating from known high-risk regions. Deprioritize individual IP blocking for this activity, as the infrastructure appears highly ephemeral and distributed.
