From the paper [1]:
Each round of attack consists of three steps.
In the first step, the cache is primed, i.e.,
the attacker completely fills some of the
cache sets with its own data. The attacker
then waits some time to allow the
victim to execute. Finally, the attacker
probes the cache by measuring the time
it takes to access the previously-cached
data ...
From a brief glance, it looks like they then use the timing to feed into a deep neural network classifier.

- crispyambulance 8y agoIt seems like a very difficult and iffy technique to get NOT a lot of information. We're talking here about an attacker finding out what website domain names are open in other tabs on a target's browser? Is that a big deal?

- theWheez 8y agoFor you and me, probably not, but perhaps of interest to a state agency to attempt to profile the use of sites by a foreign intelligence's members. It is probably difficult to say which sites one is using, but an easier task would be to profile by time and IP address that it seems that this group of people visits site A a lot around X time.
