Threat Intelligence Briefing

Global threat activity changed by several orders of magnitude (2,817 → 25,357 events), with attacks and malware C2 dominating. The US, Canada, and the Netherlands remain top sources, but Russia and South Korea show increased SSH brute-force activity. Nordic countries exhibit routine noise, with Sweden (73 events) and Finland (40) seeing typical scanning and anonymizer traffic. The spike suggests a coordinated campaign rather than isolated incidents, with Dutch ASNs (e.g., <a href="https://ip.wayscloud.services/ip-intelligence/146.190.237.146" target="_blank">146.190.237.146</a>) heavily involved in SSH attacks. Defender actions should prioritize rate-limiting SSH traffic from NL/RU ASNs and monitoring for C2 callback patterns in malware alerts. Deprioritize individual IP blocking unless clustered with known campaign indicators.
