New critical security vulnerabilities affecting wireless networks have just been announced. These weaknesses in WPA2, a protocol that secures all modern protected Wi-Fi networks, are in the Wi-Fi standard itself, not in individual products or implementations. This means that an attacker within range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). In plain English, attackers can use this new technique to read information that was supposed to be safely encrypted. This can be used to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and any information you transmit through your network. The attack works against all modern protected Wi-Fi networks.
If Beta Brain manages your network you can relax and finish your golf tournament without rushing. Moreover, have a glass of wine when you’re done! We have already identified at-risk customers and, together with Meraki, have deployed a firmware patch to address these vulnerabilities.
If we do not manage your network, skip the golf and the wine. Make sure all your devices are updated as well as the firmware of your router. Please note that changing the password of your Wi-Fi network does not prevent the attack. The only prevention is updating your network equipment as soon as security updates become available.
As always, if you have any questions please contact us and we’ll be happy to help.
