Spectra's new vulnerability breaks the distinction between Wi-Fi and Bluetooth
The threat was identified by experts from educational institutions in Germany and Italy.
The vulnerability was named Spectra, with its help a potential attacker can attack the chipsets responsible for processing various types of wireless communications (Wi-Fi, Bluetooth, LTE).
“A new type of vulnerability - Spectra - exists because the transmission takes place in the same range, and combined wireless chips must determine access to the channel,” the researchers describe the security problem.
It’s also known that Spectra uses “coexistence mechanisms,” which allow chips to switch between wireless technologies at incredible speeds. The principle of coexistence improves productivity, but the downside is the possibility of attack through third-party channels.
Thus, in theory, an attacker can extract data transmitted over a wireless connection that supports combined chipsets.
“In particular, we analyzed the Broadcom and Cypress chipsets that are used in popular devices like the iPhone, MacBook and Samsung Galaxy S series. During testing, we were able to level the distinction between Wi-Fi and Bluetooth,” experts continue.
Specialists promise to talk more about Spectra at the Black Hat conference, which will be held in August.
