Apple’s AiPort firmware puts the whack on KRACK

Apple has updated its updated its existing AirPort devices with firmware updates that patches vulnerabilities to KRACK attacks that allow a malicious hacker to bypass WPA2 encryption on Wi-Fi networks and make a user's data easy to view.

KRACK (Key Reinstallation AttaCK) can expose information shared on Wi-Fi networks, even over connections “secured” with data encryption and passwords. The vulnerability breaks WPA 2, the strongest and most common form of encryption used to protect data on home and business Wi-Fi networks.

Both firmware versions can be downloaded and installed via Apple's AirPort Utility on Macs or iOS devices. Version 7.7.9 is for 802.11ac hardware; the 7.6.9 version is available for 802.11n devices.
