Security Firm Detects Restricted Nvidia Processors Inside China Telecom Systems

Israeli security firm Lava has identified 32 restricted Nvidia Blackwell Ultra B300 processors operating inside the network of China Telecom, a state-owned telecommunications provider. The presence of this hardware raises questions about export compliance, as these specific units are barred from sale to unauthorized entities, including buyers in China. Nvidia has not disputed the existence of these units but characterized the scale of unauthorized distribution as statistically negligible.

The discovery was made using Nvidia's own DCGM Exporter tool. While designed for data center health monitoring, this software can sometimes be accessed externally and, in certain instances, does not require password authentication. The exact location of the processors within the company's infrastructure remains unknown, and Lava cannot confirm the specific server racks where they are installed. Nvidia has previously acknowledged the need for a tool to locate chips but has not yet released such a utility.

The timeline of this issue extends back to 2025, when reports indicated that one billion dollars' worth of Nvidia AI hardware entered China within a three-month period. At that time, B200 units were the primary target, though distributors were already preparing to move newer B300-series chips. The desire for this specific hardware stems from its capabilities; the B300 offers fifty percent more memory and FP4 compute than the previous generation, making it highly sought after for advanced artificial intelligence workloads.

Enforcement actions regarding these chips have escalated in recent months. In August, nine individuals were indicted in Taiwan over illegal exports to China. This legal action followed reports that Supermicro had terminated several employees following an internal investigation into smuggling operations. The illicit supply chain involved a Taiwanese server trading firm that maintained whitelisted status for purchasing graphics processors.

Nvidia has addressed the issue by noting that unauthorized diversion of controlled products remains under one-half of one percent in recent court cases. A spokesperson for the company stated that they view such activity as a drop in the bucket compared to the volume of domestic computing resources already available in China. The company reiterated that, with tens of millions of units in service across approved nations, smuggling does not impact their overall operations.

The pressure to acquire Nvidia hardware persists despite these restrictions. Demand for even older silicon has driven prices sharply upward, with five-year-old A100 servers now costing up to eighty-two thousand dollars. This scarcity has led some users to attempt repurposing gaming hardware for artificial intelligence tasks, though the Blackwell Ultra B300 remains a primary target for those seeking to build new infrastructure.
