The unfortunate news of the day has to do with the serious flaws in the WPA2 protocol that affect virtually anything that uses WiFi and that could allow an attacker to intercept all traffic between a device and the wireless access point.

We already explained how it works in Android and Linux, systems that are especially compromised by the failure, but they are not the only ones. Fortunately, in the case of those who use versions with Windows support and update immediately, they will be protected.

Microsoft explained to The Verge that it has already released a security update to correct the problem. Those who have automatic updates active or install the update manually would be out of danger.

Details about the patch for Windows will be published later this day.

And the other systems?

Apple has not yet clarified if the latest versions of iOS and macOS are vulnerable . For its part, Google has promised to publish a solution for the affected devices in the coming weeks.

The good news in all this is that it is a problem that can be solved with simple security updates on your devices, WPA2 is not going to be obsolete overnight.

The bad, at least for Android users, is that with the huge fragmentation of the mobile operating system and the huge number of devices maintained by different companies, there is no guarantee that at least a fraction will end up benefiting from a patch on the part of of Google. You will have to wait to see if your manufacturer updates your device.

Activate automatic updates

These kinds of things tend to remind us of the importance of keeping automatic updates on Windows active. If you use Windows 10 it is most likely that this is your case, if you use Windows 7 or 8 / 8.1 make sure to do so.

Activate automatic updates in Windows 10:

• Press the Windows + I key to open the Configuration panel
• Click on Update and security> Windows Update . If you want to manually check for updates, select Check for updates.
• Select Advanced Options , and then under Choose how updates should be installed, select Automatic (recommended).

Activate automatic updates in Windows 8.1:

• Place the mouse cursor in the lower right corner of the screen and move it upwards. Select Settings> Change PC settings> Update and recover> Windows Update .
• Select Choose how updates should be installed and then, under Major updates, select Install updates automatically (recommended) .

Activate automatic updates in Windows 7:

• Click on the Start button and in the search box, type Update. In the list of results, select Windows Update .
• In the left pane, select Change settings, and then under Major updates, select Install updates automatically (recommended) .
