GoKawiilSecurity firm Lava finds 32 banned Nvidia B300 chips in China Telecom network
Israeli security firm Lava says it identified 32 Nvidia Blackwell Ultra B300 chips operating inside the network of state-owned China Telecom, despite these chips being barred from export to China under U.S. controls. Lava says it detected the chips using Nvidia's own DCGM Exporter monitoring tool, though it cannot confirm exactly where in China Telecom's infrastructure they reside. Nvidia did not dispute the finding but said diversion of controlled chips remains statistically insignificant.
