KRACK Attack: How safe is your WiFi connection?

A disturbing flaw in Wi-Fi networks has allowed for hackers to eavesdrop on data being passed through most modern Wi-Fi networks. This means that any device, from laptops and mobile phones to games consoles and tablets, could all be vulnerable to hacking with credit card numbers, passwords, chat messages and emails all potentially under threat.

Known as a key reinstallation attack or KRACK for short, this newly discovered flaw was unearthed by Marty Vanhoef, a Belgian researcher. What’s more, the researcher claims that the problem is not limited to any one device or operating system and instead is an issue with Wi-Fi as a whole.
