In the first part of the paper, the authors show how to get your EC2 instance co-located (i.e. running in in the same hypervisor) with the instance you are targeting (the one you want to spy on). Once this is achieved, they describe side channel attacks to glean information from this situation.

This paper got me thinking. I noticed that it does not mention trying to go after disk blocks and memory. I don’t know if they didn’t try or they tried and were defeated.
