To validate our findings, we have tested 18 popular BLE commercial products with 5 Android phones. In this paper we show that the BLE programming framework of the initiator must properly handle SCO initiation, status management, error handling, and bond management otherwise severe flaws can be exploited to perform downgrade attacks, forcing the BLE pairing protocols to run in an insecure mode without user's awareness. However, the BLE specification does not require the SCO mode for the initiator, and does not specify how the BLE programming framework should implement this mode.

To defeat security threats such as man-in-the-middle (MITM) attacks, Bluetooth Low Energy (BLE) 4.2 and 5.x introduced a Secure Connections Only (SCO) mode, under which a BLE device can only accept secure pairing such as Passkey Entry and Numeric Comparison from an initiator, e.g., an Android mobile. Moreover, when testing our chip-based vulnerabilities on those devices, we find BlueFrag, a chip-independent Android RCE. Turning off Bluetooth will not fully disable the chip, making it hard to defend against RCE attacks. We uncover a Wi-Fi/Bluetooth coexistence issue that crashes multiple operating system kernels and a design flaw in the Bluetooth 5.2 specification that allows link key extraction from the host. Given RCE on a Bluetooth chip, attackers may escalate their privileges beyond the chip's boundary.
We demonstrate the potential of Frankenstein by finding three zero-click vulnerabilities in the Broadcom and Cypress Bluetooth stack, which is used in most Apple devices, many Samsung smartphones, the Raspberry Pis, and many others.
The speed-up of our new fuzzing method is sufficient to maintain interoperability with the attached operating system, hence triggering realistic full-stack behavior. Frankenstein brings firmware dumps "back to life", and provides fuzzed input to the chip's virtual modem. In this paper, we present Frankenstein, a fuzzing framework based on advanced firmware emulation, which addresses these shortcomings. Generic over-the-air fuzzing suffers from several shortcomings, such as constrained speed, limited repeatability, and restricted ability to debug.

Since most implementations and firmwares are closed-source, fuzzing remains one of the main methods to uncover Remote Code Execution (RCE) vulnerabilities in deployed systems. Wireless communication standards and implementations have a troubled history regarding security. Our analysis provides the first security argument, in any formalism, that the patched WPA2 protocol meets its claimed security guarantees in the face of complex modern attacks. Our model is the first that is detailed enough to detect the KRACK attacks it includes mechanisms such as the four-way handshake, the group-key handshake, WNM sleep mode, the data-confidentiality protocol, and their complex interactions. In this work, we address this situation and present an extensive formal analysis of the WPA2 protocol design. Perhaps because of this, there exists no formal or cryptographic argument that shows that the patches to the core protocol indeed prevent the corresponding attacks, such as, e.g., the notorious KRACK attacks from 2017. In particular, it involves various mechanisms that interact with each other in subtle ways, which offers little hope for modular reasoning.
The protocol, which is specified on more than three-thousand pages and has received various patches over the years, is extremely complex and therefore hard to analyze. The IEEE 802.11 WPA2 protocol is widely used across the globe to protect network connections.
