Lava says it identified 32 Nvidia Blackwell Ultra B300 GPUs in China Telecom network
Lava, an Israeli security firm, says it identified 32 Nvidia Blackwell Ultra B300 chips inside the network of China Telecom, a state‑owned telecommunications provider. The chips are barred from export by U.S. controls, according to a report by The Information, and were spotted using Nvidia’s DCGM Exporter tool, which can be accessed beyond the data‑center network and sometimes lacks password…
Key points
- Lava says it found 32 Nvidia Blackwell Ultra B300 GPUs inside China Telecom’s network.
- The B300 chips are export‑controlled; U.S. rules bar sales to China and require whitelisted buyers.
- In August 2026, nine people were indicted in Taiwan for illegal B300 exports, and Supermicro fired employees after a probe.
Nvidia downplayed the report but did not deny it, with a spokesperson noting that diversion of controlled U.S. products is "less than one half of one percent in recent court cases." In 2025, $1 billion worth of Nvidia AI chips were reportedly smuggled into China in three months, with B200 chips then most sought‑after and distributors already gearing up for B300‑series chips. The B300, announced in March last year, offers 50% more memory and FP4 compute than the B200 and was expected to ship by the end of 2025. In August 2026, nine people were indicted in Taiwan over illegal B300 exports, and Supermicro said it fired several employees after an investigation involving the Taiwanese firm Flying Tiget Tech. Nvidia’s older A100 servers have tripled in price, reaching up to $82.,000.
