Threat Intelligence Briefing

Global threat volume increased by 19.1% compared to the previous 6-hour period, primarily driven by a surge in malware C2 and SSH brute force activity. This represents a significant deviation from the recent baseline and is not routine background noise. The Nordic region remains stable with low overall volume; Sweden saw the highest activity with 10 events across attacks, botnet, and SSH brute force, consistent with its 7-day average. Top threat countries remain the US, Brazil, and Romania. Focus on the pattern of SSH brute force originating from ASNs in Eastern Europe and Asia rather than individual ephemeral IPs. Consider temporarily rate-limiting SSH connections from high-risk ASN ranges, particularly those hosting the top observed threat IPs from Russia, Bulgaria, and Vietnam. Prioritize investigating any successful SSH authentication attempts from these regions. Deprioritize individual IPs from the Netherlands and Romania as they represent lower-volume, persistent background noise.
