Not sure where this should go, so figure toss it in the windows forum where it may get the most visibility...
All kinds of articles flying around after this announcement today. This is one, and google will find a whole bunch more.
I saw the announcement this morning as well. It's a major flaw in WPA2 that affects every wifi device with WPA2 ever made. For minimal protection, use HTTPS. For better protection, use an encrypted proxy server connection. To reduce the possibility of hacking from road warriors, when when traveling and at wifi hot spots, turn wifi off when it's not needed.
And very, very fast. One article I read said that Windows 10 was patched but is still vulnerable to one variant of the attack. Some devices may never have a patch available, such as routers or Android devices over 2 years old, the majority of IoT devices and Windows XP or Vista computers. Many devices that have a patch available may not get upgraded, either due to lack of automated updates or failure by consumers to install patches or upgraded firmware. Then there are all the business and institutional customers who use dated systems due to mission critical legacy software and internal IT policies. Hackers are going to have a field day with this one.
