Tizen is samsung's newest OS for it's devices and considered by them as the operation system of everything, aiming to run on every device from simple IoT, mobile phones, televisions to even...Cars. Over the last few months I observed that samsung is laying the groundwork for a larger expansion of tizen in the mobile world. It appeared that samsung is adding more servers and more infrastructure to support an upcoming growth in the amount of tizen users worldwide and is planning to expand to new markets. I then decided to start and research tizen due to the fact that it seems that nobody is doing it! The tizen mobile firmware was obtained pretty quickly and from a thorough investigation it seems that samsung hasn't learned anything from the publications about 0days in the past few years. The code is not designed with security in mind, is not up to any modern security standards (you can find strcpy, memcpy, sprintf almost anywhere. and always to a fixed size buffers). during the course of a few days I found over 40 different vulnerabilities in tizen - some logical and some just classic (really classic!) memory corruptions bugs. Almost every system app is vulnerable. My name is Amihai Neiderman, 27 years old. I worked with computers for the last 20 years, doing everything from high-level programming to bare metals electronics. I've always programmed for fun and problem solving and eventually found myself in the world of information security after finding "bugs" in websites competing with my own one. In the past 8 years I mostly do vulnerability research in windows, Linux and various embedded devices Today I work as a security researcher for Azimuth security.
