Up to 50% of Android devices impacted by WPA2 vulnerability

Wi-Fi marinini Shuttersctock 2013

This could involve passwords, credit card numbers, photos and messages sent over a network to be stolen, or cyber attacks to be inserted into the traffic. The bottom line: "If your device supports WiFi, it is most likely affected".

The full finding of vulnerabilities discovered will be made public by the KU Leuven team on November 1 at the ACM Conference on Computer and Communications Security in Dallas.

This client-based attack uses a flaw in the "handshake" component of the WPA protocol that negotiates and confirms the validity of encryption keys between client and wireless network devices.

What that means is the vulnerability potentially impacts a wide range of devices including those running operating systems from Android, Apple, Linux, OpenBSD and Windows. While this makes the attack a lot riskier, it's little comfort considering how widespread WPA2 encryption is used.

If you discover from browsing the CERT advisory that there is an update available or your computer, wireless device or access point, take care to read and understand the instructions on updating those devices before you update. "There is no evidence that the vulnerability has been exploited maliciously", the organization added.




Most companies will no doubt be releasing security patches to fix this issue ASAP, so keep a look out for any available updates. "We updated to protect customers as soon as possible, but as a responsible industry partner, we withheld disclosure until other vendors could develop and release updates". The Consumerist, which notes that "basically every device on earth" is affected, says users should also install security updates on any connected devices as soon as prompted.

Since the loophole is at the very basic level - the Wi-Fi standard itself - another cybersecurity expert Jiten Jain says users will have to wait for a firmware update for their routers and other devices.

"The attack works against all modern protected Wi-Fi networks", Vanhoef writes.

While the patches are arriving, internet users are advised to visit on secure https websites and stay away for low-quality non-https websites. And you can watch the video above for additional information. Sites beginning with HTTPS:// would be relatively safer. The ideal solution right now would be to unhook these devices from the Wi-Fi network, and check with the manufacturer for KRACK patches.
