At Modal, we built a serverless container runtime enabling users to attach up-to eight latest generation NVIDIA GPUs to a function. Such an ability, combined with an on-demand billing model, is catnip to cryptomining abusers. These cryptominers steal valid credit card information and then squat on as many GPUs as possible for as long as possible, running up Modal’s costs and keeping valuable GPUs out of the hands of legitimate, paying users. This unhappy situation could not stand, so we added a syscall-based program analysis component into our runtime that detects and disables cryptomining Modal Functions before banning the offending user and all their friends.
