This week you may have seen in different publications across the media a news story about all WiFi networks being vulnerable to hacking from KRACK which is short for Key Reinstallation Attacks. This kind of attack can lead to personal information such as credit cards, photos and emails to be stolen. Passwords and other valuable information is at risk and the attack can affect any modern device that uses WiFi.
Researchers from KU Leuven University in Belgium were able to find a way to read sensitive information over a WiFi network that is using WPA2. With this in mind it may also be possible for an attacker to implant malicious information onto a WiFi network in the form of malware and ransomware.
So what is WPA2 and why is it important to my WiFi network? WPA2 is a protocol that protects your WiFi network, previously WPA2 was thought as a secure encryption key with wigle.net suggesting that it secures 60% of the worlds WiFi networks.
All devices that support WiFi can be affected by KRACK however this doesn't mean you need to go out and buy any new devices or hardware. Since news broke about KRACK major vendors that include; Apple, Amazon, Microsoft and Cisco have all been scrambling to create a new update which will protect against a KRACK attack. Bleeping Computer have compiled a full list of vendors that are affected and added notes on what they are doing about the vulnerability, to see the list click here.
Public WiFi will be a huge risk and unless you are certain that the network you are connecting to is secure, I'd think twice to using it.
