Threat Intelligence Briefing

Global threat activity increased by 14.3% compared to the prior 6-hour period, with reconnaissance dominating at 110k events—consistent with recent patterns. The rise is primarily driven by infrastructure in the US, China, and India, with notable contributions from Google LLC and DigitalOcean, LLC IP ranges. Nordic countries remain stable, with SE and FI showing typical abuse patterns including SSH brute force and malware C2, but no significant deviation from baseline. Most threats align with persistent scanning and automated attack campaigns rather than new or targeted activity. Consider temporary blocking or rate-limiting on CIDR ranges tied to repeat malicious behavior in Google and DigitalOcean networks, particularly those associated with malware C2. Deprioritize isolated brute force attempts from single IPs in high-reputation ASNs unless part of larger clusters. Focus monitoring on residential and datacenter IPs showing repeated categorization as anonymizers or malware C2, as these show higher persistence than ephemeral scanners.
