You may have already read about this issue or heard about it on the news. A Wi-Fi vulnerability recently discovered by researchers (https://papers.mathyvanhoef.com/ccs2017.pdf) is being referred to as KRACK. Apparently, it affects WPA2 (stands for Wi-Fi Protected Access II) the security protocol used by most Wi-Fi networks today.
THE PROBLEM:
The flaw may allow hackers to perform wireless network identity theft and view anything flowing between your device and the network.
Somewhat offsetting this risk are sites that are protected with Secure Sockets Layer (SSL) encryption (these sites begin with HTTPS://) may not be intercepted by hackers if their certificates are correctly configured. In addition, the hackers would need to be in physical proximity to your Wi-Fi network to access it.
WHAT CAN WE DO ABOUT IT?
- Update your devices and router with patches as they become available. One source you can check for status of patches and fixes is Charged Blog (https://char.gd/blog/2017/wifi-has-been-broken-heres-the-companies-that-have-already-fixed-it).
- Limit or discontinue Wi-Fi use until patched. Theoretically, a hacker could sit in a car on the street or in a parking lot in range of a Wi-Fi network and access it. Especially with mobile devices you may want to turn off your Wi-Fi and use data instead.
- Secure and use Virtual Private Network (VPN) software. Three available popular programs include Nord VPN, Private Internet Access and HotSpot Shield.
- Be on the lookout for additional information as it occurs.
