    There is/was a critical vulnerability in the firmware of these boxes, that could potentially be exploited by a remote hacker.

    QUOTE - "They found vulnerabilities in a feature allowing users to create backups of their custom configurations (such as port forwarding and dynamic DNS settings).

    Although configuration backups were encrypted, the private encryption key was the same across all hubs in the UK. This meant that an attacker with access to the administrative interface of a user's hub could download a configuration file, add additional instructions to enable remote access and restore the file to the hub.

    The technique would have given moderately skilled miscreants to ability to pwn devices and monitor traffic in and out of the hub.

    VM have rolled out a silent patch, which should have automatically updated these routers remotely (standard VM practice). However, I am not certain how an affected user can check to see if this patch has been implemented (usually requires a manual reboot of the router).
