Smuggled Nvidia Chips Found in State-Owned Chinese Network
Security firm identifies 32 banned B300 GPUs inside China Telecom's infrastructure, highlighting persistent gaps in export controls.
By Mariana Delgado ·

Thirty-two Nvidia Blackwell Ultra B300 graphics processing units have been identified inside the network of China Telecom, a state-owned telecommunications provider. This discovery is significant because U.S. export controls have already barred these specific chips from leaving the country. The finding raises immediate questions about how hardware meant for whitelisted buyers ended up in a Chinese data center where it is technically restricted.
The timeline of this issue shows a pattern of persistent leaks. In 2025, reports indicated that Chinese firms smuggled $1 billion worth of Nvidia AI chips into the country in just three months. At that time, the B200 was the primary target, but distributors were already preparing to move B300-series units once they became available. The current discovery suggests that the flow of controlled chips has not stopped despite ongoing efforts to restrict them.
Nvidia has responded to the report by downplaying its impact. A spokesperson stated that the diversion of controlled products is a "drop in the bucket" compared to the vast amount of domestic compute China already possesses. The company noted that recent court cases have shown insignificant diversion rates, often less than half of one percent. Nvidia maintains that with tens of millions of GPUs in service in approved countries, smuggling remains a non-factor due to blocking efforts by governments on both sides of the globe.
The method used to locate the chips offers a glimpse into data center vulnerabilities. Lava, an Israeli security firm, identified the hardware using Nvidia’s DCGM Exporter tool. This software is installed by data center operators to monitor server health and performance. Although designed for internal use, the tool can sometimes be accessed from outside the network and does not always require password authentication. It is currently unknown exactly where within China Telecom's infrastructure the chips are located, or the specific route they took to arrive there.
Demand for the B300 remains high due to its capabilities. Announced in March of last year, the chip offers 50% more memory and FP4 compute than the previous-generation B200. Nvidia marketed it as "built for the age of reasoning," citing advanced models like DeepSeek R1. The chip was expected to ship by the end of 2025 and quickly became a target for illicit trade. In August 2026, nine people were indicted in Taiwan for illegally exporting B300 GPUs to China. This followed an investigation by Supermicro, which fired several employees linked to the smuggling ring. The scheme involved a Taiwanese server trading firm called Flying Tiget Tech, which held whitelisted status for GPU purchases.
The scarcity of new chips has also driven up prices for older hardware. Nvidia’s A100 servers, which are five years old, have seen prices triple and can now cost up to $82,000. The pressure on supply has led some organizations to retool gaming GPUs to handle AI workloads where possible. As Nvidia continues to work on a tool to help locate its chips, the discovery of these 32 units serves as a reminder that export controls face constant challenges in a high-demand market.
What happens next remains to be seen. Nvidia has not yet released the tool it previously confirmed it was developing to track its hardware. Until that system is live, security firms will likely continue to use existing monitoring tools to spot controlled chips in restricted networks. The situation underscores the difficulty of managing global supply chains for critical technology while balancing trade restrictions and market demand.
