Threat Intelligence Briefing

Global threat volume changed by several orders of magnitude (2,001 → 15,416 events), representing a severe deviation from typical behavior. This surge is driven by a massive increase in spam and attack traffic, primarily originating from US, NL, and CN ASNs. Nordic region volumes remain stable and consistent with their 7-day baselines, showing no signs of being targeted by this specific global campaign, which appears to be a large-scale, coordinated botnet activation. Focus on the pattern, not individual IPs, as the source addresses are ephemeral. Consider temporarily implementing enhanced rate-limiting for SSH and web application traffic originating from the top contributing ASNs in the US and Netherlands, as this is a clear pattern of automated aggression. Deprioritize individual IP blocking; instead, monitor for clusters of activity from these network ranges.
