A serious weakness in the WPA2 protocol, widely implemented as the recommended default security protocol for all Wi-Fi networks, was disclosed publicly yesterday. This advisory seeks to inform you of the vulnerability and advise what steps have been taken by Milnsbridge to address this issue and also to notify you of potential security risks and how best to mitigate them. This advisory is a high-level overview and is not intended as in-depth analysis of the vulnerability.
KRACK stands for Key Reinstallation AttaCKs. Put simply this type of vulnerability can be abused to potentially steal sensitive information such as credit card numbers, usernames and passwords. It can also be potentially used to inject and manipulate data sent to or from affected devices. (Man in the middle)
The attack works against all modern protected WI-FI Networks, this includes wi-fi enabled devices at work and home, as well as mobile devices. An attacker needs to be in range of your wireless network therefore shared multi-tenant buildings are particularly vulnerable. The vulnerability can be exploited via the client operating system such as Microsoft Windows (All versions), Apple IoS, Google Android or via the wireless access points, so updating both is highly recommended at this stage.
No. The wi-fi password is not recovered in these attacks so is not at risk. However, as a good practice it is also recommended to regularly review and change static passwords used on Wi-Fi networks.
