Ngebray.com,- Devices connected to Wi-Fi are at greater security risk of hacking than previously thought. A researcher discovered flaw, known as KRACK, in the security protocol used in most Wi-Fi devices.
A hacker could exploit KRACK to inject malware, such as ransomware, into websites. The attacker would reuse a key that’s provided when a client device attempts to join a Wi-Fi network. They could then decrypt information exchanged between the access point and the device leaving personal information like credit card numbers, messages and passwords exposed.
Any device that supports Wi-Fi is likely affected by KRACK and more than 40% of Android devices are especially at risk. To protect yourself from KRACK attacks, you should update Wi-Fi devices as updates become available. If possible, you should also update your router’s firmware.
