What to do re Wifi Krack attack?

Most of you may have already seen on the news or read about a serious new Wi-Fi vulnerability discovered recently. While I don’t believe there is a strong chance that you will get hacked this way in the very near future, I would advise you to conduct all sensitive and financial internet operations via a wired Internet connection instead of Wi-Fi on your laptop or desktop computer.

If you want to use your smartphone to conduct sensitive operations and you have a data plan, i.e. internet available everywhere outside your home, you can protect yourself by turning your phone’s Wi-Fi Off. Once you are completed your operations you can turn Wi-Fi back on. The same goes for tablets. However tablets with data plans are rare.

If you aren’t sure if you have a data plan, it’s easy to find out: if you turn off your device’s Wi-Fi reception and you can still go on the internet, you have a data plan.

If you have a “smart home” or any item connected to or accessible by the internet, such as a security camera, thermostat, fridge or others, I would enquire about any updates from your vendors. However be prepared to wait.

If you are on the road for work, or during a pleasure trip and you need to conduct financial operations online, make sure you are using your own data plan. If you do not have a data plan and need to use a hotel’s Wi-Fi or any public Wi-Fi connection, make sure you install a VPN in your computer or device. Use the VPN during any sensitive operation. Private Tunnel is the one that I use. It’s free for 7 days and very economical after that. https://www.privatetunnel.com/home/

Microsoft said an automatic security update issued last week had fixed the problem for Windows 7, 8.1 and 10 users. However if your computer is set up to not install updates automatically you can read below for links to patches.

If you are using Windows* 10, you can obtain a security patch here: https://www.catalog.update.microsoft.com/Search.aspx?q=KB4041676
If you are using Windows* 8.1, you can obtain a security patch here: https://www.catalog.update.microsoft.com/Search.aspx?q=KB4041687
If you are using Windows* 7, you can obtain a security patch here: https://www.catalog.update.microsoft.com/Search.aspx?q=KB4041678

*X86 refers to 32-bit Windows version. X64 refers to 64-bit Windows version. If you unsure about your version, go to Control Panel, then System. The information will be stated there.

If you are using a Mac, Apple is working to release a patch within “weeks”.
If you are using an iPhone or an iPad, Apple is working to release a patch within “weeks”.

If you are using an Android smartphone or tablet: “Google said it would release a patch on November 6. However, since Android manufacturers have to release their own security updates, it may be months until some phones are safe, and others may never be secured.”
