A Belgian researcher has discovered a weakness in WPA-2, the security protocol used in the majority of routers and devices including computers, mobile phones and connected household appliances, to secure internet and wireless network connections.
The researcher, Mathy Vanhoef, has named the flaw KRACK, for Key Reinstallation Attack.
Any device that supports Wi-Fi is likely to be affected by KRACK, albeit devices will have different levels of vulnerability depending on their operating systems. Linux and Android are believed to be more susceptible than Windows and iOS, and devices running Android 6.0 are reportedly particularly vulnerable.
