Researchers Uncover New Coexistence Attacks On Wi-Fi and Bluetooth Chips
Dec 16, 2021
Cybersecurity researchers have demonstrated a new attack technique that makes it possible to leverage a device's Bluetooth component to directly extract network passwords and manipulate traffic on a Wi-Fi chip, putting billions of electronic devices at risk of stealthy attacks. The novel attacks work against the so-called "combo chips," which are specialized chips that are equipped to handle different types of radio wave-based wireless communications, such as Wi-Fi, Bluetooth, and LTE. "We provide empirical evidence that coexistence, i.e., the coordination of cross-technology wireless transmissions, is an unexplored attack surface," a group of researchers from the Technical University of Darmstadt's Secure Mobile Networking Lab and the University of Brescia said in a new paper . "Instead of escalating directly into the mobile [operating system], wireless chips can escalate their privileges into other wireless chips by exploiting the same mechanisms...
