Now the newest on this series is called Hertzbleed Attack. It is a a new family of side-channel attacks: frequency side channels. Hertzbleed takes advantage that, under certain circumstances, the dynamic frequency →
Meltdown and Spectre are vulnerabilities in modern computers that can be used to leak passwords and sensitive data. Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware vulnerabilities allow programs to steal data which is currently processed on the computer. The vulnerabilities were found in 2017 by several researches, but were kept secret →
