Cybersecurity firm blames Wi-Fi chips

If you’ve been using an iPhone, iPad, Amazon Echo or Kindle or certain handsets from Google, Samsung or Xiaomi, there is a chance that your device has been accessed or taken over by hackers, thanks to a recently discovered vulnerability in the WiFi chips used in these devices.

ESET, a Slovak cybersecurity firm, has for the last one year been working in collaboration with manufacturers of two specific WiFi chips, which were found to have been vulnerable to attack by hostile parties.

The manufacturers have since released for all the vulnerable devices security patches that users can install to address the vulnerability.

ESET discovered that WiFI chips manufactured by Broadcom ad Cypress had the Kr00k vulnerability.

ESET said the devices that tested positive for the vulnerability include the Amazon Echo (2nd generation), Amazon Kindle (8th generation), Apple iPad mini 2, Apple iPhone 6, 6s, 8 and XR, Apple MacBook Air Retina 13-inch 2018, Google Nexus 5, 6, and 6s, Samsung Galaxy S4 GT-19505, Samsung Galaxy S8 and Xiaomi Redmi 3s, as well as some WiFi access points by Huawei and Asus.

“Simply put, any device with a WiFi chip manufactured by these two companies is vulnerable to attack, as long as the device is connected to a WiFi network and the hacker is within the range of the same network,” a cybercrime official said. “Once a hacker gets access to any device for even a short period of time, they can do anything, including planting a malware or intercepting sensitive information that is being sent or received via the Internet,” the official added.
