Lava Reports 32 NVIDIA B300 GPUs Operating Inside China Telecom

Security firm Lava reported that it found 32 NVIDIA Blackwell Ultra B300 GPUs operating inside the network of China Telecom, a state-owned telecommunications company.

The GPUs were located remotely, according to the report. Lava’s findings suggest that U.S. export controls have not prevented these high-performance AI chips from reaching Chinese infrastructure. The report says the units appear to have arrived through illegal means, but the source summary provides no details about how they were obtained.

The summary does not include further evidence or details from Lava’s investigation. It also ends before giving NVIDIA’s full response, so the company’s position cannot be established from the available source material.
