Refresh Your Approach to Wi-Fi to Protect from KRACK Attacks

Recent research has brought to light a vulnerability in WPA2, the security certification commonly used alongside WPA. Key reinstallation attacks (KRACK) can bypass WPA2 to access wireless attached devices and gain personal information like passwords and credit card numbers. This can also extract sensitive data that was assumed to be encrypted and inject malware or ransomware. The attacker only has to be on the same network as the targeted device to gain access.

Since KRACK is based on a vulnerability in Wi-Fi security, the only real way to guard against it is to make sure all wireless devices are running the latest software, as many wireless device companies have already issued patches. Work with your IT professional to ensure all devices have been updated.
