Recently a security researcher helped us to identify a potential vulnerability in our Keychain Remote USB software that would make it possible for someone with physical access to your Keychain Remote USB to extract your system configuration settings. We are providing a software update to the Easy Setup Wizard to patch the issue. Instructions on how to get the update are at the bottom of this article. Non-USB Keychain Remotes are not impacted.
