GPU attack can crash power grid

Researchers from Zhejiang University devised Bit2Watt, an attack where malicious cloud tenants use GPU workloads to destabilize datacenters and electrical infrastructure. The attack can induce voltage excursions, harmonic distortion, and damping degradation. A 1,000-GPU assault on a 1-MW grid could create 46.8 percent total harmonic distortion, potentially triggering cascading failures and blackouts exceeding 80 percent.
