As reported by Secure Mobile Networking Labs researchers at the Technical University of Darmstadt, Apple's iOS 12 mobile operating system presents a security vulnerability. As a result, devices such as the iPhone or the iPad can be planted with simple means. According to researchers, about half a billion devices are affected.

Are Apple products like the iPhone too expensive?
Are these China spy tokens really available?
For an attack, you need a Wi-Fi compatible laptop and a programmable board costing about 22 euros. In addition to iOS, this vulnerability also affects MacOS, tvOS and watchOS. Scientists therefore recommend to users of mobile Apple devices to install the latest updates (iOS 12.1, macOS 10.14.1, tvOS 5.1 and watchOS 5.1). This will solve the problem.
Technical background
With features such as Airplay, Apple device users can easily stream wireless data between them. For this to work, protocols such as Apple Wireless Direct Link (AWDL) are used in the background.
But that's where the risks lie, as explains Matthias Hollick, professor at TU Darmstadt: "In simple terms, we use Bluetooth LE to ring the bell and the active AWDL target device . " send to the target device, not completely cleanly checked, which allows us to flood the device with an absurd input. "Result: The target device and all nearby devices can be blocked at the same time.
No security on Android
Although the discovery vulnerability only affects Apple devices, researchers say that Android users can not weigh themselves. Because a new standard of Wi-Fi Alliance, called NAN (Neighbor Awareness Networking), relies on AWDL. Scientists are therefore waiting for similar vulnerabilities to be hidden in the NAN.
