Israeli security firm Lava identified 32 Nvidia Blackwell Ultra B300 chips linked to IP addresses associated with China Telecom. These chips are subject to US export controls that prohibit their sale to China due to national security concerns.

The researchers discovered the hardware by scanning publicly exposed instances of Nvidia’s DCGM Exporter, a monitoring tool often left unsecured by operators. Lava noted that this network association does not confirm physical ownership or the exact location of the hardware.

The findings are part of a broader study released by Lava on October 9, 2026, which identified approximately 2,100 exposed DCGM Exporter hosts globally. The report also highlighted a vulnerability in Nvidia systems, tracked as CVE-2026-47483, with a severity rating of 8.2.

Lava estimates the value of the B300 chips and similar advanced GPUs involved in such scenarios at over $100 million. The research also points to increasing prices for advanced AI hardware on gray and black markets within China.
