All patches available so far to protect Wi-Fi networks from KRACK
We learned that the WPA2 security protocol, the most widelyused in WiFi networks, had been compromised, basically endangering everything that was capable of connecting to a wireless network.
Through an exploit named KRACK, researcher Mathy Vanhoef showed how vulnerability can be exploited to intercept and manipulate all traffic sent by a device.
The bug had been known for several months and organizations and companies had been informed to prepare patches before the information was released to the public to prevent it from being exploited (there are still no reports that this has happened).
Yesterday we could also know that Microsoft had released a patch for all versions with Windows support and that you only need to keep the system up to date and preferably always have automatic updates active, which in cases like these demonstrate the essentials that can become.
Technically they are only completely safe so far Windows 7, Windows 8 / 8.1, Windows 10, and the latest versions of iOS. The 41% of Android devices are vulnerable, you can impact KRACK greatly Android 6.0+.
Who is updating?
Microsoft seems to be one of the few technological giants that was on top of the problem and has already solved, others offer the same vague response about patches in the coming weeks, but at least work on it.
