Threat Intelligence Briefing
Analysis period: 2026-03-31T12:00:02.081816 - 2026-03-31T18:00:02.081816 (6 hours)
Executive Summary
Global threat volume decreased by 58.1% compared to the previous period, representing a significant deviation from typical high-volume activity. This decline is consistent with weekend patterns and reduced automated attack traffic. SSH brute force attacks remain the dominant threat category, with notable clusters originating from Vietnamese (ASN 45899) and Bulgarian (ASN 8866) networks. Nordic countries show routine low-level activity, with Finland (9 events) and Sweden (8 events) experiencing expected background noise primarily consisting of attacks and brute force attempts. Focus monitoring on persistent SSH brute force patterns rather than individual IPs, as these represent the most consistent threat vector. Consider temporary blocking or rate-limiting traffic from ASNs demonstrating concentrated SSH attack patterns, particularly during peak activity hours. Deprioritize individual IP responses unless they show sustained high-volume attack patterns.
