The researcher uncovered 24-year-old Wi-Fi vulnerabilities

In 2016, Belgian researchers Mathy Vanhoef and Frank Piessens discovered a serious re-attack type vulnerability on the Wi-Fi protocol. This gap is called KRACK and is unfortunately known. At that time, these researchers not only discovered this bug, but Mathy Vanhoef renamed all the vulnerabilities discovered: FragAttacks.

According to him, these vulnerabilities could be exploited by hackers to intercept sensitive data or to show users fake websites. The Belgian researcher goes even further and claims that the risks persist even when a secure WPA2 or WPA3 WiFi is used. In this way, attackers can even take advantage of other devices connected to the network. For full technical details on how these vulnerabilities work, you can visit Mathy Vanhoef’s website.

24 year old bug

The latter suggests that some of the flaws in networks can be exploited using the WEP security protocol, and adds that they have been around since Wi-Fi was first implemented in 1997. Vanhoef always points out that these errors are there to warn users very common and can affect many devices which means there are many updates to be done.

Some companies have already released fixes for some of their devices. This is especially true for Microsoft, Cisco, Intel, Lancom, Lenovo, Samsung, NetGear and many others. To find out whether you are affected by these vulnerabilities or not, you can consult the list compiled by Mathy Vanhoef.

While waiting for a real solution to protect all users from these risks, the Belgian researcher gives back some basic advice. We can’t repeat it enough, but it’s important to keep your devices up to date, use secure and unique passwords, and especially not visit shady websites. It is also highly recommended that you use HTTPS as often as possible.
