WebAs an example, in our paper we demonstrate an attack against OpenSSH in which we use RAMBleed to leak a 2048 bit RSA key. However, RAMBleed can be used for reading other data as well. RAMBleed is based on a previous side channel called Rowhammer, which enables an attacker to flip bits in the memory space of other processes.
