A market-leading garage door controller is so riddled with severe security and privacy vulnerabilities that the researcher who discovered them, Sam Sabetan, is advising anyone using one to immediately disconnect it until they are fixed. Immediately unplug all Nexx devicesThe result: Anyone with a moderate technical background can search Nexx servers for a given email address, device ID, or name and then issue commands to the associated controller. Anyone using a Nexx device should seriously consider disabling it and replacing it with something else, although the usefulness of this advice is limited since there’s no guarantee that the alternatives will be any safer
