Smart Meters: I'm Hacking Infrastructure and So Should You (Hash Salehi)

Why Smart Meters? This is a question Hash is often asked. There's no bitcoin or credit card numbers hiding inside, so he must want to steal power, right? Openly analyzing the technology running our critical infrastructure and publishing the findings is something Hash is passionate about. In the wake of the great Texas freeze of 2021, we can no longer "hope" those in power will make decisions that are in the people's best interest. This talk will present research on the Landis+Gyr GridStream series of smart meters used by Oncor, the largest energy provider in Texas. Cyber attacks on Industrial Control Systems (ICS) differ in scope and impact based on a number of factors, including the adversary's intent, sophistication and capabilities, and familiarity with ICS and automated indutrial processes. In order to understand, identify and address the specific points that can prevent or stop an attack, a systematic model known as "Cyber Kill Chain" is detailed, a term that comes from the military environment and registered by the Lockheed Martin company. While most are familiar with terms and theoretical diagrams of how security should be implemented, in this talk we want to present live how an attack chain occurs from scratch to compromise industrial devices, the full kill chain, based in our experiences. The goal is to land these threats into the real world without the need to carry out these attacks with a nation-state budget.
