Security Firm Identifies Smuggled Nvidia B300 Chips Inside China Telecom Network

Israeli cybersecurity firm Lava has identified 32 Nvidia Blackwell Ultra B300 graphics processing units operating within the network of China Telecom, a major state-owned telecommunications provider. These specific chips are subject to U.S. export controls, which prohibit their sale to sanctioned parties, including entities in China. The discovery highlights the persistent challenge of tracking high-performance hardware after it leaves the custody of whitelisted buyers who agree to keep the components within approved markets.

The presence of these 32 units underscores a broader trend of diversion. In 2025, reports indicated that Chinese companies smuggled approximately $1 billion worth of Nvidia AI chips into the country over a three-month period. While the B200 model was the primary target during that surge, distributors were already preparing for the B300 series. The B300, announced in March 2025, offers significant advantages over its predecessor, including 50% more memory and FP4 compute capability. It was originally slated for shipment by the end of 2025 and has since become a highly sought-after asset for AI data centers.

Lava’s researchers located the chips using Nvidia’s Data Center GPU Manager (DCGM) Exporter tool. This software is typically 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 data center’s network and often lacks mandatory password authentication. While Nvidia has acknowledged the utility of its tracking tools, a dedicated solution for locating specific chips has not yet been released, leaving some visibility gaps.

Nvidia has responded to the findings with a measured tone, neither fully denying the report nor overstating its impact. A spokesperson stated that the diversion of controlled U.S. products has historically been insignificant, citing recent court cases where such instances amounted to less than 0.5% of total shipments. The company characterized this discovery as a "drop in the bucket" compared to the vast volume of domestic compute hardware China already possesses. Nvidia emphasized that with tens of millions of its GPUs in service in approved countries, smuggling remains a non-factor, largely blocked by governmental oversight on both sides of the Pacific.

The logistics of how these specific chips reached China Telecom’s server racks remain unclear, and Lava has not confirmed their exact location within the network. However, the incident fits a pattern of sophisticated smuggling operations. In August 2026, nine individuals in Taiwan were indicted for the illegal export of B300 GPUs. This followed an internal investigation at Supermicro, which resulted in the termination of several employees. The smuggling operation reportedly utilized a Taiwanese server trading firm, Flying Tiget Tech, which held whitelisted status for GPU purchases.

The high demand for Nvidia’s latest silicon has driven prices for older hardware to record levels. A100 servers, despite being five years old, have seen their prices triple, reaching up to $82,000 per unit. This scarcity has led some operators to retool gaming GPUs for AI workloads when newer hardware is unavailable. For Midwest readers tracking the AI infrastructure race, this incident serves as a reminder that the flow of critical computing power remains a complex interplay of technology, regulation, and international trade enforcement.
