Cyber-Physical Analysis of Weapons of Mass Destruction Detection Systems: Part 1 - DARPA's SIGMA

Index 1.  Introduction 2.  Practical Gamma Spectroscopy for Security Researchers 3.  SIGMA Network 4.  Conclusions Disclaimer To avoid any misunderstandings, I want to clarify that all the information in this post is based on open-source intelligence, publicly available documents, and reverse engineering. I have not attempted to compromise or replicate any potential attacks on internet-facing SIGMA systems. Instead, I conducted a simple, non-invasive reconnaissance phase, which involved accessing public websites, reviewing their source code, and examining generic endpoints to gather general information, such as system versions.  A month before publishing this post, I gave a heads-up about it to those who needed to be informed, just in case. Introduction  This is the first part of a series on the cyber-physical analysis of weapons of mass destruction detection systems, focusing on technologies like CBRN networks and nuclear safeguards. These posts will cover...
