The “Krack Attack” Wi-Fi encryption security flaw is more than a little frightening, but you should already be relatively safe if you’re utilizing a recent Windows PC. Microsoft has released a patch that fixes the vulnerability on all supported versions of Windows (effectively, 8 or later). Windows isn’t as susceptible to the flaw as Linux-based systems like Android, which don’t demand a distinctive encryption key, but this fix may have a significant impact simply through the sheer ubiquity of Windows in the computing world.

To recap: the exploit revolves around cloning a WPA2-encrypted Wi-Fi network, impersonating its MAC address and changing the Wi-Fi router. Intruders can power your device to connect to the bogus network rather than the genuine one, which makes it easier to allow them to snoop on your computer data traffic or perpetrate attacks that want an area network. Would-be hackers need to get within physical distance of a target network because of this to achieve success, but that’s possibly an enormous problem for general public networks.

All Linux powered systems are supposed to fall to the exploitable category as they don’t ask for any unique encryption key fingerprint from the Wi-Fi Router. Hence the system can be tricked to change the channel of the Wi-Fi signal with an identical fake connection.

For other platforms?

Apple hasn’t detailed a fix yet.

Android?

With the November 6th, 2017 security update Google’s own Pixel devices will be the first to receive fixes.

What about other Manufactures?

There are a number of the smartphones running old Android versions which will not receive this update since Manufactures has to do OTA to serve the update.

We reached out to many manufacturers, but they are not clear when they can provide an update for the same.

No Updates on Blackberry devices are available.

The Wi-Fi Alliance is also needing that all of its partners (including Apple) check for the exploit and patch if necessary. The issue is already at hand. The main concern is whether or not updates get to a timely manner.

When the Windows was attacked by the WannaCry operating system, Microsoft did patch the older version of Windows. As the KRACK is a critical vulnerability, the company may be also planning to release the security update to Windows XP since it’s still being used by many.
