MDS-Micro architectural Data Sampling

MDS is a family of vulnerabilities in different (related) components of the processor. Unlike Meltdown, MDS doesn’t allow an attacker to directly control the target memory address from which they would like to leak data. Instead, MDS is a form of “sampling” attack in which an attacker can leverage cache side-channel analysis to repeatedly measure […]

A New Side Channel attack arrived: SWAPGS

The SWAPGS vulnerability is a speculative execution side-channel vulnerability that allows bad actors to read data from privileged memory. In order to increase performance in CPUs, a feature called speculative execution will execute instructions before it knows if they are needed or not. Vulnerabilities that target this feature are called side-channel attacks.
