Chinese security researchers have discovered more than a dozen vulnerabilities in the onboard compute units of BMW cars, some of which can be exploited remotely to compromise a vehicle. The research of BMW cars is an ethical hacking research project. In the research, Keen Security Lab performed an in-depth and comprehensive analysis of both hardware and software on in-vehicle infotainment Head Unit, Telematics Control Unit and Central Gateway Module of multiple BMW vehicles. Through mainly focusing on various external attack surfaces, (including GSM network, BMW Remote Service, BMW ConnectedDrive System, Remote Diagnosis, NGTP protocol, Bluetooth protocol, USB and OBD-II interfaces), Keen Security Lab has gained local and remote access to infotainment components, T-Box components and UDS communication above certain speed of selected multiple BMW vehicle modules and been able to gain control of the CAN buses with the execution of arbitrary, unauthorized diagnostic requests of BMW in-car systems remotely.
In embedded systems, many peripherals are connected to the main processor with busses like I2C, SPI, and UART, which do not support enumeration. Therefore, when an embedded system uses an operating system, such as Linux, it is necessary to convey the hardware configuration of the system, i.e. all the information about the connected peripherals, to the OS in a standard form. The most common way to do this in Linux is to use a device tree.
There have been many announcements about what would be the next generation Intel Xeon platform with integrated FPGA, also 
Patients were downloading audio files of the “eRemedies” on doctor’s website.
What happens when a file gets executed in Linux? What does it mean that a file is executable? Can we only execute compiled binaries? What about shell scripts then? If I can execute shell scripts, what else can I execute? In this article we will try to answer those questions.
The Allwinner ARM processors are very popular in a large number of hobbyists development boards, and more and more widely used in embedded products. Support for those processors was initiated in the official Linux kernel by Bootlin (formerly Free Electrons) engineer Maxime Ripard in 2012, and has since then been improved up to the point where actual Allwinner-based products are being shipped with the official Linux kernel.
