Threat Intelligence Briefing
Analysis period: 2025-12-31T00:00:02.003564 - 2025-12-31T06:00:02.003564 (6 hours)
Executive Summary
Global threat activity changed by several orders of magnitude (3,710 → 28,651 events), representing a significant deviation from the previous 6-hour period. Attacks (6,575 events) and spam (5,612) dominate, with the US, Netherlands, and China as top origin countries. Nordic activity remains stable except for Sweden (140 events), showing elevated scanning and SSH brute force attempts from anonymizer and botnet-linked IPs. Russian IP <a href="https://ip.wayscloud.services/ip-intelligence/45.135.232.92" target="_blank">45.135.232.92</a> (14 attacks) and Korean IPs <a href="https://ip.wayscloud.services/ip-intelligence/125.141.233.20" target="_blank">125.141.233.20</a>/<a href="https://ip.wayscloud.services/ip-intelligence/211.197.62.36" target="_blank">211.197.62.36</a> (21 combined attacks) exhibit concentrated SSH brute force patterns. Consider temporary rate-limiting for /24 ranges from ASNs associated with these clusters, particularly NL-hosted SSH attackers. Deprioritize individual IP blocking for anonymizer traffic, which shows no new TTPs. Swedish defenders should prioritize web attack patterns from botnet-linked CIDRs.
