Apple Patches KRACK with AirPort Firmware Updates

KRACK WPA2 WiFi security flaw

Apple released a pair of AirPort firmware updates to patch the KRACK vulnerability on Tuesday. AirPort Base Station Firmware Update 7.6.9 was released for AirPort base stations with 802.11n, while AirPort Base Station Firmware Update 7.7.9 was released for older AirPort base stations that support 802.11ac.

KRACK is a vicious vulnerability that affected WiFi devices far and wide. It allowed attackers to potentially get even encrypted data going over a network.

  • Apple patched Macs running High Sierra, Sierra, and El Capitan with a security update on the 1st of November to protect against this hack. This latest firmware update protects one if you’re using an Airport Extreme or express with some other brand of computer, I think. Were older Apple routers susceptible to this vulnerability?

  • I’m with Mr Kheit here. Didn’t Apple assert that they/we were safe from the KRACK ? Liar, liar, pants on fire !

    I see that my older AirPort units (the ones that look like laptop chargers) didn’t get an update, and I still use them for connecting non WiFi enabled printers to my home network. Is Apple forgetting that there’s still a lot of them out here in the wild ?
