SANS says there are no reports of it being exploited yet. It’s also a local threat meaning someone would have to come to Williams and set up a special network to trick anyone. We have some protection against such a configuration. This doesn’t protect anyone’s home network however, and there are patches available for Microsoft computers which will stop the threat at the computer level. Apple has stated they will release updates shortly. It is important to remember that part of installing updates is rebooting the computer. Often the computer will stay in a vulnerable state until it is restarted. You should be in the habit of restarting your computer at least once a week.
