Nvidia B300 GPUs on Chinese Networks: 12,000 GPU Study (lava.security)

In a revealing investigation by Lava, over 12,000 NVIDIA GPUs were uncovered across 2,000 public IP addresses, with 32 of these being the advanced B300 GPUs from NVIDIA's Blackwell Ultra generation identifiable through unsecured monitoring endpoints in China. This finding is particularly significant given the U.S. export controls on high-performance AI chips, raising concerns over compliance and the physical locations of these GPUs, although the research does not confirm any regulatory violations. The analysis also highlighted that about 86% of the 374 Blackwell GPUs were configured in eight-GPU setups, suggesting their use in compute servers rather than personal gaming systems. Additionally, the research shed light on the utilization of these GPUs, revealing that nearly 60% reported zero utilization at observation times, which underscores the need for better oversight of publicly accessible GPU monitoring systems that could expose critical infrastructure to potential cyber threats. Alongside the B300s, the analysis found a substantial number of consumer-level RTX 4090 GPUs being repurposed for computational tasks, indicating a growing convergence between consumer hardware and advanced computing environments. These findings signal an urgent need for stricter security measures to protect sensitive AI infrastructure from external vulnerabilities while highlighting the ongoing evolution of AI data center configurations.
