Automated Security Analysis of Embedded Devices

Recent advances of Internet of Things brought along a lot of changes, but not only good ones. On the subject of cyber security, there were some big drawbacks connected to advances in the IoT-world. This was clear once big cyber attacks used IoT devices to perform attacks all over the internet. A good example of a malware that did this is Mirai. This malware infected IoT devices and used them to perform attacks on popular sites like Google and GitHub. It managed to bring them down for a whole day. Botnets like Mirai rely on already infected devices to track down and infect poorly secured or improperly configured devices. Once compromised, these devices are then integrated into the botnet. In order to defend against these attacks, we need to know how they are attacking us. To get to know this, a honeypot can be used, An IoT honeypot is a computer system that pretends to be an poorly secured IoT device in order to attract and log information about attacks [1]. This information can then be leveraged to fend off future attack attempts. This thesis presents a dynamic and expandable framework for IoT honeypots. This framework can emulate different devices and the different protocols these devices use. These honeypots gather information about the attacks that it encounters on the internet. This dynamic and expandable platform can change the banners it displays and the way it responds to different commands, this will make it harder for attackers to detect that we are a honeypot. We used the framework to develop and deploy three different honeypots. These honeypots can be deployed in different configurations and they yield different results when deployed in another configuration. With this platform we can make automated attacks think that we are real IoT devices, and these automated attack will then try to infect our honeypot.
