Datacenters tax utilities normally, so just imagine what they could do if workloads were designed to destroy!

AI datacenters wreak havoc on the power grid under normal circumstances, so what happens if a bad actor controls all the GPUs and wants to cause harm? Cybersecurity researchers in China have devised a way for malicious tenants to attack their infrastructure provider, potentially causing blackouts or damaging equipment. 

The attack, dubbed Bit2Watt, imagines an adversary masquerading as a legitimate cloud tenant to launch GPU workloads that have the potential to damage datacenters and supporting electrical systems. It's intended to demonstrate the need to extend cybersecurity defenses to datacenter workload scheduling.

In reality, the threat isn't running a lot of GPUs at 100% -- they do that all the time -- it is cycling the GPUs up and down in a pattern just fast enough to confuse the control system! The risk isn't overloading the grid, but creating a distorting wave.

Think of it like the same problem architects have to account for when designing bridges because high winds can create standing waves through resonance.
