Threat Intelligence Briefing

Global threat volume increased by 20.3% versus the previous 6-hour period, representing a significant deviation from the baseline. The surge is primarily driven by malware C2 (1601 events) and attack traffic (1265 events), with top-source countries being India, Germany, and the US. Nordic activity remains low and stable, consistent with routine background noise. The top threat IPs are overwhelmingly associated with SSH brute force campaigns, indicating a concentrated, automated attack pattern rather than a broad-based threat. Focus on the campaign behavior, not individual ephemeral IPs. Consider implementing temporary rate-limiting rules for SSH traffic originating from the ASNs associated with the top-source countries, particularly for internet-facing infrastructure. Deprioritize individual IP blocking due to the high volume and rapid rotation of attacking hosts.
