Abstract

All Spectre attacks so far required local code execution. We present the first fully remote Spectre attack. For this purpose, we demonstrate the first access-driven remote Evict+Reload cache attack over the network, leaking 15 bits per hour. We present a novel high-performance AVX-based covert channel that we use in our cache-free Spectre attack.
We show that in particular remote Spectre attacks perform significantly better with the AVX-based covert channel, leaking 60 bits per hour from the target system. We demonstrate practical NetSpectre attacks on the Google cloud, remotely leaking data and remotely breaking ASLR.
