Don’t Look Now But Someone Just Cracked WPA2 WiFi Security

Wireless security has always been something of a problem. Basic WEP encryption, for example, has been beaten so soundly that it’s a wonder device makers even offer it as a security option anymore. Fortunately, we’ve had WiFi protected access 2 (WPA2) keeping our networks safe--but perhaps no longer.

According to Phys.org, researchers at universities in the UK and Greece discovered a way to crack WPA2, and apparently it’s not all that difficult.

The researchers published their work in the International Journal of Information and Computer Security, where they outlined how WPA2 protection can be compromised. Hackers can use a brute force password attack to exploit a network, although the longer and more complex the password, the longer it takes.

Further, during a de-authentication step wherein network devices must re-authenticate with a new encryption key, there’s a temporary backdoor left open. With the right tools, a hacker can locate and exploit that back door. Also, MAC addresses can apparently be spoofed when a network admin restricts access to devices with specific identifiers.

So happy weekend folks, there’s something else for you to worry about.
