Threat Intelligence Briefing

Global threat volume changed by several orders of magnitude, surging from 3,049 to 21,915 events. This is a significant deviation from the baseline, primarily driven by a massive increase in spam, attacks, and malware C2 activity. The US, Brazil, and the Netherlands are the top source countries. Nordic volumes remain within expected parameters, with Sweden (224 events) showing the highest but routine activity profile. The top threat IPs are associated with botnet C2 and SSH brute force campaigns, not isolated events. Focus defensive actions on the /24 CIDR blocks associated with the top malicious ASNs, particularly those hosting the botnet C2 infrastructure. Consider temporary blocking or rate-limiting traffic from these network ranges. Deprioritize individual IPs from the spam surge as they are highly ephemeral.
