WiFi users are at risk due to a vulnerability which allows hackers to create malicious networks, decrypt data and even inject malware onto devices. Everything you do online, including your banking and password details, can be spied on.
Researchers have discovered a glaring vulnerability in WiFi Protected Access 2 (WPA2) – a core encryption protocol used by WiFi users to keep their web activity private.
“This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on,” Researcher Mathy Vanhoef from KU Leuven University in Belgium explained in the KRACK Attacks report. “The attack works against all modern protected Wi-Fi networks.”
An attacker in range of a target’s device can exploit weaknesses in WPA2 using key reinstallation attacks (KRACKs), which allows them to view data that’s meant to be encrypted.
