Tom’s Hardware reported on Oct. 23, 2026, that Israeli security firm Lava identified 32 NVIDIA Blackwell Ultra B300 GPUs in NVIDIA DCGM Exporter monitoring data associated with China Telecom’s network. The report did not date Lava’s identification.

What Lava reportedly identified

NVIDIA DCGM Exporter monitors server health and performance. Tom’s Hardware said Lava used data from the tool to identify the 32 GPUs. It described the exporter as sometimes accessible from outside a data center’s network and as sometimes operating without password authentication.

Lava could not confirm where the GPUs were located within China Telecom’s network or how they reached China. Tom’s Hardware described China Telecom as a state-owned Chinese telecommunications company.

NVIDIA’s response

An unnamed NVIDIA spokesperson told Tom’s Hardware that diversion of controlled U.S. products was insignificant, citing a figure below 0.5% in recent court cases, and called smuggling a “nonfactor.” The response addressed diversion broadly; Lava’s reported identification concerned 32 GPUs associated with monitoring data.

Tom’s Hardware reported that U.S. export controls barred B300 chips from export to China.
