Threat Intelligence Briefing

Global threat volume increased significantly by 37.2% compared to the previous 6-hour period, representing a clear deviation from baseline activity. This surge is primarily driven by a concentrated spike in malware C2 traffic (1015 events) and SSH brute-forcing, predominantly from Dutch (ASN 20473, 43350) and Russian (ASN 48347) network blocks. Nordic activity remains low and routine; Sweden's 12 events are consistent with its 7-day average, showing no anomalous patterns. Focus on the campaign-level activity from these specific ASNs rather than ephemeral IPs. Consider implementing temporary rate-limiting rules for SSH traffic originating from the identified Dutch and Russian CIDR ranges, as these represent the primary attack vectors. Deprioritize individual IPs from the top list, as they are likely part of larger, shifting botnet infrastructures.
