The Cyber Dimension of the Zaporizhzhia NPP Occupation

The war that began with Russia's full-scale invasion of Ukraine has led to a series of unprecedented nuclear-related situations. During the first 48 hours, Chernobyl—a symbol of the deep-seated fear of nuclear disaster, especially within Europe—was taken by Russian troops. This was accompanied by reports of  radiation spikes, various plots involving dirty bombs and nuclear materials, and Russian soldiers allegedly killed by acute radiation syndrome. In the end, all of it was proven to be as fictitious as the reported radiation levels. We should view these mutual accusations between Ukraine and Russia as part of the information war, which likely didn’t come as a complete surprise to those in the know. For instance, in an insightful piece Politico published documenting the 'first-ever oral history of how top U.S. and Western officials saw the warning signs of a European land war,' John Kirby stated the following: Without time to recover from the shock caused by the events ...

Addressing the Exploitation of Radiation Fear: A Self-Assessment Guide to Counter Disinformation

In December 2024, two events —drone sightings in the US and Israel’s strike on Syria’s weapon depots— were followed by orchestrated reports of detected radiation spikes. Some media outlets took these dubious reports (with millions of views) that originated from social media , and published pieces based on them. In one of these cases, the actors behind the disinformation campaign exploited a real-time radiation map, which is maintained by a private company  that manufactures personal dosimeters, to sustain the narrative. Kim Zetter has recently published " Anatomy of a Nuclear Scare ", an article that covers this issue. This trend does not come as a surprise, as radioactivity is one of those few things that can collectively trigger significant levels of societal anxiety and emotional, rather than rational, response, which is often disproportionate to the actual physical risks it poses. This radiation fear has been shaped during years by a mix of cultural, historical, and media...

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 ...

Ukraine's nuclear regulator confirms Chernobyl's post-invasion radiation spikes had an 'abnormal origin'.

First off I would like to provide some context for those readers who are not familiar with this topic. In 2023 I presented at BlackHat USA ' Seeing Through the Invisible: Radiation Spikes Detected in Chernobyl During the Russian Invasion Show Possible Evidence of Fabrication '. Kim Zetter also wrote an investigative  piece . The research materials are publicly available. As I casually discovered a few days ago, around the date I received  the acceptance notification from BlackHat, the paper ' Preliminary assessment of the radiological consequences of the hostile military occupation of the Chornobyl Exclusion Zone ' was submitted to the 'Journal of Radiological Protection'. This paper would be eventually approved and then published in September. So it seems that both investigations were being performed in parallel, but unfortunately we never crossed our paths. There is also a significant detail: this investigation doesn't come from a random guy like me, but ...
