Through my own negligence and naivety, my AWS account became compromised. The lucky hacker managed to create 236 x EC2 Instances and 268 x EBS Volumes, racking up about $1000 in my billing. I took to removing the instances manually, but had to go through the process of turning off termination protection in the UI, before terminating the instance.
This was slow, tedious, and after about 4 instances I got annoyed.
This script can be run via Powershell to kill off every one of your instances in every region. As a pre-requisite, you'll need to have the AWS CLI pre-installed, and have your AWS account configured via aws configure.
