South Korean cybersecurity stocks extended a rally for a second consecutive day after Nvidia CEO Jensen Huang identified cybersecurity as likely to become AI’s next major application. SAND Lab rose 29.95% to 7,160 won by 9:14 a.m. on the 14th, hitting its daily price limit, before paring gains to 22.50% by 9:53 a.m. Other gainers included Fasoo AI, Monitors Lab, Hanssak, S2W, CyberOne, Dream Security, XGate and RaonSecure. Huang said accelerating AI-driven programming would increase both cyberattacks and the development of defensive patches, potentially shifting the industry toward dynamic, AI-based threat detection and response. His broader comments at Goldman Sachs’ technology conference also covered AI infrastructure constraints, investment and the expanding computing supply chain.
