New Bit2Watt Attack Could Let Cloud Tenants Disrupt Power Grids Without an Exploit

A cloud tenant using nothing but ordinary GPU access can push a data center's power draw up and down fast enough to threaten the grid it runs on, with no exploit and no break-in. That is the claim behind Bit2Watt , described by three Zhejiang University researchers in a paper accepted to CHES 202...

Bit2Watt: A Cyber-Physical Vulnerability Exploiting GPU Workloads across Power and Computing Infrastructures

Modern data centers increasingly rely on large-scale GPU clusters and on-site renewable energy resources, resulting in a tightly coupled cyber-physical system between computing workloads and power-electronic-dominated grids. In this paper, we reveal Bit2Watt, a previously unexplored vulnerability...
