Illegal Nvidia B300 GPUs found in China Telecom network, U.S. export controls challenged

By PulseAugur Editorial · [1 sources] ·

An Israeli security firm, Lava, has identified 32 Nvidia Blackwell Ultra B300 GPUs within the network of China Telecom, a state-owned Chinese telecommunications company. These high-performance chips are subject to U.S. export controls and are intended for whitelisted buyers who agree not to send them to China. Despite Nvidia's claims that chip smuggling is a minor issue, this discovery indicates a continued challenge in preventing controlled technology from reaching China. The exact method by which these B300 chips entered China Telecom's network remains unknown, though Lava utilized Nvidia's DCGM Exporter tool for identification. AI
