A major Wi-Fi vulnerability has been announced on Monday, 16th of October, 2017. This is a flaw in the standard and a high risk to every single Wi-Fi connection out there, corporate and domestic. Most or all correct implementations of the standard will be affected. In other words the attack works against all modern protected Wi-Fi networks and affects every device you own that uses Wi-Fi.
Please see the BBC article for more details:
Security measures like AV or firewall will not prevent your network from being hacked.
Minimise Wi-Fi use, and avoid using public Wi-Fi networks altogether. Try to use cellular (3G/4G) networks instead till the issue is resolved.
Attackers can use the flaw to steal sensitive information (bank details, credit card numbers, passwords, chat messages, emails, photos, etc). As this is the connection that is being ‘stolen’ anything that is transferred over the wireless network is vulnerable.
The vendors that make Wi-Fi products are working on patches which they will release in the coming days. As they release the patches, you will need to update your devices and hardware. If you need help doing this please get in touch with us.
