In this post I am talking about adapting 10 and 100 megabit twisted pair Ethernet to use coaxial cable instead of twisted pair wiring. Those 10BASE-T and 100BASE-TX Ethernet st standards use two wire pairs for communications (one for TX and other for RX). In this article I am describing how to adapt them to →
Critical side-channel vulnerabilities in modern processors became well known in 2018 with Meltdown and Spectre vulnerabilities. And several more same type vulnerabilities followed. 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 →
