Smuggled Nvidia Chips Discovered in China Telecom Network

Israeli cybersecurity firm Lava has identified thirty-two units of Nvidia’s Blackwell Ultra B300 graphics processing units operating within the infrastructure of China Telecom. This state-owned telecommunications giant provides core communication services across China, making the presence of these specific chips a notable development in the ongoing trade technology debate. The discovery highlights how high-performance computing hardware is still reaching Chinese data centers despite strict regulatory barriers.

The B300 is one of Nvidia’s most advanced data center GPUs, designed to handle complex artificial intelligence workloads. Under current U.S. export control rules, these specific chips are prohibited from being shipped directly to China. To sell them, Nvidia must grant approval to specific buyers who agree not to transfer the hardware to sanctioned parties. The fact that these units are now active in a Chinese network suggests that the standard export control mechanisms have been bypassed or circumvented in this instance.

This incident is part of a broader pattern of high-end chips entering the Chinese market through unofficial channels. In 2025, reports indicated that approximately one billion dollars’ worth of Nvidia AI chips were smuggled into the country over a three-month period. While the B200 model was the primary target at that time, distributors had already begun preparing for the B300 series, anticipating its launch and high demand. The recurrence of such findings suggests that the flow of controlled hardware remains a persistent challenge for regulators on both sides of the Pacific.

Nvidia has responded to the news with relative calm, though it did not dispute the findings reported by Lava. A company spokesperson stated that the diversion of controlled U.S. products has historically been minimal, noting that recent court cases have found the volume to be less than half of one percent. The spokesperson described this leakage as a drop in the bucket compared to the vast amount of domestic computing power China already possesses. With tens of millions of GPUs already in service in approved countries, Nvidia maintains that smuggling is a non-factor that is effectively blocked by governments globally.

The exact method by which the B300 chips entered China Telecom’s server racks remains unclear. Lava could not pinpoint the specific location of the chips within the company’s network, but they confirmed their presence using Nvidia’s own DCGM Exporter tool. This software is typically installed by data center operators to monitor server health and performance. Although intended for internal use, the tool can sometimes be accessed from outside the data center’s network and does not always require password authentication, which may have facilitated the detection process. Nvidia has previously acknowledged work on a tool to locate its chips but has not yet released it.

The demand for the B300 is driven by its significant performance advantages over its predecessor. Announced in March of last year, the chip offers fifty percent more memory and FP4 computing power than the B200. Nvidia positioned the hardware as being built for the age of reasoning, specifically citing its suitability for sophisticated large language models like DeepSeek R1. Originally expected to ship by the end of 2025, the chip quickly became a sought-after asset in the AI industry.

The high value of these chips has led to increased scrutiny and legal action regarding their illegal export. In August 2026, nine individuals in Taiwan were indicted for illegally exporting B300 GPUs to China. This indictment occurred shortly after Supermicro fired several employees following an internal investigation into smuggling activities. The smuggling operations involved a Taiwanese server trading firm known as Flying Tiget Tech, which held whitelisted status for GPU purchases, allowing it to act as a conduit for the hardware.

The scarcity of newer models has also affected the pricing of older Nvidia hardware. The A100 servers, which are five years old, have seen their prices triple, with some units costing up to eighty-two thousand dollars. As the crackdown on smuggling continues, some buyers have resorted to retooling gaming GPUs to run AI workloads when high-end data center chips are unavailable. This shift underscores the critical importance of Nvidia’s silicon in the current AI infrastructure landscape.

While Nvidia argues that the overall impact of smuggling is small, the discovery within a major state-owned network like China Telecom adds a layer of complexity to the narrative. It serves as a reminder that export controls, while effective, are not impenetrable. The ongoing efforts by both U.S. and Chinese authorities to track and restrict these flows will likely continue, with security firms like Lava playing an increasingly visible role in uncovering hidden hardware.
