Has anyone made a sandbox site running every type of container and presenting a shell where users can try to break out of any uncompromised ones remaining?
It's self-evident that we should only run containers that haven't been pwned yet.
I suspect that with all of the CVE-20XX exploits, Heartbleed, Meltdown, Rowhammer, Spectre, etc, that we're all living in a fantasy and there simply are no secure containers.
