Are your Apple AirPorts suddenly flashing yellow? That’s because Apple has sent out a major update to your AirPort Express, AirPort Extreme, and AirPort Time Capsule base stations.
Apple discovered a vulnerability in the firmware of the AirPorts that could allow attackers to execute commands on the affected devices.
Luckily, it’s a snap to update your devices. Just go to AirPort Utility, and there will be a small, red notification next to the devices that need to be updated. Just click on that device and then on the “update” button for each device, and they will automatically update. Continue the process for each AirPort on the network.
