In the last post from a couple of days ago we posted about RECESSIM's YouTube series about smart meter hacking. Hackaday have noted that Hash, the security researcher behind the RECESSIM channel will be hosting a Hack Chat on April 14 noon pacific time. If you're unfamiliar with them, hack chats are live chat events where you can chat directly with an expert on a particular topic.
That electrical meter on the side of your house might not look like it, but it's pretty packed with technology. What was once a simple electromechanical device that a human would have to read in person is now a node on a far-flung network. Not only does your meter tote up the amount of electricity you use, but it also talks to other meters in the neighborhood, sending data skipping across town to routers that you might never have noticed as it makes its way back to the utility. And the smartest of smart meters not only know how much electricity you're using, but they can also tease information about which appliances are being used simply by monitoring patterns of usage.
While all this sounds great for utility companies, what does it mean for the customers? What are the implications of having a network of smart meters all talking to each other wirelessly? Are these devices vulnerable to attack? Have they been engineered to be as difficult to exploit as something should be when it's designed to be in service for 15 years or more?
These questions and more burn within Hash, a hardware hacker and security researcher who runs the RECESSIM reverse-engineering wiki. He's been inside a smart meter or two and has shared a lot of what he has learned on the wiki and with some in-depth Smart Meter Hacking videos. He'll stop by the Hack Chat to discuss what he's learned about the internals of smart meters, how they work, and where they may be vulnerable to attack.
