Security firm Lava discovered 32 Nvidia Blackwell Ultra B300 chips linked to China Telecom, suggesting US export controls were circumvented.
Key points
- Israeli firm Lava found 32 Nvidia Blackwell Ultra B300 chips.
- The chips were connected to systems linked to state-owned China Telecom.
- This discovery occurred despite existing US export controls on the hardware.
Israeli security company Lava identified 32 Nvidia Blackwell Ultra B300 chips. These high-performance processors were connected to systems linked to the network of state-owned operator China Telecom. The discovery indicates that these restricted components reached their destination despite US export controls designed to prevent such transfers. The finding was reported by The Information.
What happened
Israeli security firm Lava stated it found the chips through monitoring systems. The monitoring focused on systems linked to the network of China Telecom. The chips involved are Nvidia Blackwell Ultra B300 models. These are advanced processors subject to strict US export regulations. The presence of these specific chips in systems linked to a state-owned Chinese operator is notable. It suggests a gap in the enforcement or tracking of these controls. The report comes from an outlet named The Information, which cited the findings from Lava.
Why it matters
Supply chain security relies on verifying the origin and destination of critical hardware. When advanced chips bypass export controls, it indicates vulnerabilities in tracking mechanisms. Teams usually implement strict procurement checks to ensure compliance with international regulations. This incident highlights the difficulty of monitoring hardware once it leaves the manufacturer. Organizations should assume that restricted technologies may appear in unintended locations. Understanding these flows helps security professionals assess risk in global networks. It emphasizes the need for continuous monitoring of connected systems.
The fix
- Verify the provenance of all high-performance computing hardware in your inventory.
- Audit network connections to identify unexpected links to state-owned operators.
- Review compliance procedures for restricted technologies to identify gaps.
- Monitor for unauthorized hardware additions in critical infrastructure environments.
Why it matters
Export controls are designed to manage the flow of sensitive technologies. When these controls are bypassed, it undermines the intended security posture. Professionals must recognize that hardware tracking is only one part of security. Network monitoring can reveal where these components are actually deployed. This helps organizations understand the real-world reach of restricted items. It also informs broader risk assessments for supply chain integrity. Teams should focus on visibility into their entire infrastructure.
Background: Supply chain attacks
Verify code signatures and hash values before installing any update. Monitor for unexpected outbound traffic or permission requests. If anomalies appear, isolate the system immediately and revert to a known good state. Treat third-party updates as untrusted until proven otherwise.

What to do and how to stay safe
- Audit your hardware inventory for restricted or high-performance components.
- Check network logs for connections to unexpected or state-linked entities.
- Review your procurement processes for compliance with export regulations.
- Implement continuous monitoring for unauthorized hardware changes.
