For those who missed it – the 33rd Chaos Communication Congress took place from 27.-30.12.2016 – and it was the last one in Hamburg. And I got a ticket. I haven’t seen a lot of talks, because I spent most of my time walking around the hack area and talking to people. But here are some of the talk highlights that I can recommend:
1: Shut Up and Take My Money! – The Red Pill of N26 Security
…or how a broken authentication system could lead to corrupt transactions.
2: SpiegelMining – Reverse Engineering von Spiegel-Online
I’ve built an IoT button a while ago. I’ve also written a short log of the project on hackday.io
The ESP8266, which is used here, is a small, WiFi-enabled chip which can be programmed. I hooked it up to send web request to IFTTT to trigger actions.
I started with a prototype on a ESP8266 NodeMCU development board. The button causes the ESP to send a web request to IFTTT, which is configured to send a push notification to my iPad in this example, but can trigger nearly any action that is supported by IFTTT.
after testing the firmware on the development board, I flashed it on the chip and put everything together.
IFTTT SmartButton from the inside.Tada! We do now have a battery powered push button for the internet of things.
