Crypto Briefing reported on 22 October that Israeli security firm Lava had linked 32 Nvidia Blackwell Ultra B300 chips to IP addresses associated with China Telecom, a state-owned telecommunications carrier. US export controls prohibit sales of the chips to China on national security grounds.
Lava detected the hardware through publicly accessible instances of Nvidia’s DCGM Exporter, a tool operators use to monitor GPUs. An unsecured instance can reveal details of the hardware it monitors. Crypto Briefing said the association with China Telecom addresses does not establish who owns the chips or where they are installed.
In earlier research released on 9 October, Lava identified approximately 2,100 exposed DCGM Exporter hosts worldwide. It also flagged a vulnerability tracked as CVE-2026-47483, with a severity rating of 8.2. Lava’s research indicated that the vulnerability could allow remote disruption of affected AI infrastructure.
