# New Bit2Watt Attack Lets Cloud Tenants Disrupt Power Grids Without Exploits

Researchers have identified a new attack method called Bit2Watt that allows cloud tenants to cause power grid disruptions without needing a software exploit. The attack leverages the ability to manipulate power consumption patterns by coordinating compute workloads. This matters because it exposes a novel threat to critical infrastructure from within shared cloud environments.
