Threat Intelligence Briefing

Global threat volume spiked by 135.2% compared to the previous period, representing a significant deviation from routine baseline activity. This surge is primarily driven by reputation_low and reconnaissance events, consistent with widespread automated scanning. Nordic countries show proportional increases but no anomalous patterns specific to the region. The top threat IPs, predominantly from Poland (ASN: NASK) and Romania, are part of a coordinated SSH brute force campaign that has been active for weeks, not a new threat. Focus on the campaign pattern, not individual ephemeral IPs. Consider implementing temporary rate-limiting for SSH connections originating from the CIDR ranges associated with these Polish and Romanian ASNs. Prioritize blocking these entire ranges over individual IPs, as the attack infrastructure is persistent. Deprioritize individual reputation_low events, which are high-volume background noise.
