Re: [tor-talk] Practical deanonymization using CPU load covert channels

Thanks Ethan for your research. We've been discussing which mitigation technique to use. In a virtualized context disabling c-states is only possible from the host. Thats ok since all it means is we need to package it for users to install it there.

We prefer the idea of not using the kernel commandline directly because of discrepancies between hypervisors and custom kernels. We are leaning towards using the pmqos-static.py script some_guy123 mentioned instead.

Please feel free to jump into the discussion on our bugtracker any time:
