Threat Intelligence Briefing

Global threat volume increased by 10.1% compared to the previous 6-hour period, representing a moderate but notable deviation from the recent baseline. This rise is primarily driven by increases in attacks, brute force, and spam categories. Nordic countries remained relatively stable, with Sweden (43 events) and Finland (38 events) seeing the most activity, consistent with their 7-day averages. The top threat actors continue to originate from Brazil, the US, and Turkey, focusing on SSH brute force attacks from specific Eastern European IP ranges. Focus on the pattern of SSH brute force from ASNs in Russia, Bulgaria, and Romania rather than the ephemeral individual IPs listed. Consider implementing temporary rate-limiting rules for SSH traffic originating from these high-risk ASN ranges to mitigate the increased brute force activity, which aligns with the overall global uptick.
