Wifi networks are vulnerable to hacking
WPA2 protocol used by vast majority of wifi connections has been broken by Belgian researchers, highlighting potential for internet traffic to be exposed
The security protocol used to protect the vast majority of wifi connections has been broken, potentially exposing wireless internet traffic to malicious eavesdroppers and attacks, according to the researcher who discovered the weakness.
Mathy Vanhoef, a security expert at Belgian university KU Leuven, discovered the weakness in the wireless security protocol WPA2.
Attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted.This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos and so on.
The attack works against all modern protected wifi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites.
The vulnerability affects a number of operating systems and devices, the report said, including Android, Linux, Apple, Windows, and others.
If your device supports wifi, it is most likely affected. In general, any data or information that the victim transmits can be decrypted.
Additionally, depending on the device being used and the network setup, it is also possible to decrypt data sent towards the victim (e.g. the content of a website).
