New Kr00K vulnerability affects many devices with Broadcom and Cypress Wi-Fi chips
A new vulnerability called Kr00K affects Wi-Fi chips from vendors like Broadcom and Cypress. This exploit was detailed by ESET today.
ESET, an Internet security company that offers anti-virus products, just publicly disclosed a vulnerability in Wi-Fi chips made by Broadcom and Cypress. The vulnerability, which ESET calls "Kr00K," allows for the unauthorized decryption of WPA2-encrypted network traffic. Devices with Broadcom and Cypress FullMac Wi-Fi chips, which, according to ESET, are found in the Amazon Echo/Kindle, Apple iPhone/iPad/MacBook, Google Nexus, Samsung Galaxy, Xiaomi Redmi, and more, could be vulnerable. Furthermore, even if a client device has been patched, an attacker can intercept network traffic if the wireless access point or router is unpatched.
Broadcom's new BCM4389 chip brings Wi-Fi 6E support to smartphones
Broadcom just announced BCM4589, its newest 16nm manufactured mobile networking chip that supports Wi-Fi 6E and Bluetooth 5.0.
Wi-Fi 6E is an extension to the Wi-Fi 6 standard and it lets devices operate in the 6 GHz spectrum. An additional 1200MHz can be split into fourteen 80MHz or seven wider 160MHz channels, thus offering higher throughputs. It was announced just over a month ago by the Wi-Fi Alliance, but the FCC still hasn't approved the use of the 6 GHz spectrum. Though, it looks like Broadcom is placing its bets to become among one of the first to adopt it. The company's new BCM4389 is a WiFi 6E and Bluetooth 5.0 compatible chip with a couple of welcoming features.
