A Practical Analysis of Cyber-Physical Attacks Against Nuclear Reactors

A year ago, shortly after presenting the Chernobyl research , I was kind of surprised to find out that a plethora of brand-new Teleperm XS (2nd generation) components were available on eBay.   Framatome’s Teleperm XS  (TXS) is a digital Instrumentation & Control platform designed specifically for use in safety systems in Nuclear power plants, as a replacement for, or upgrades to their analog counterparts. It is one of the most widely used digital safety I&C platforms, sustaining the main defense line (Reactor Protection System, Engineered Safety Features Actuation System) in dozens of nuclear reactors globally, including Europe, USA, Russia, and China. Obviously, that was a good opportunity to dig deeper into the, usually, closed world of nuclear digital safety I&C systems, so I bought some of the most important TXS modules.  That was the starting point for the research I'm releasing today: " A Practical Analysis of Cyber-Physical Attacks Against Nuclear ...
