How does liability work in these cases? If you had a security breach due to this security incident, would it be Docker’s liability or yours? It’s probably in the terms and conditions, but I would think it’s your liability since you can host your own registries and it’s your responsibility to act on Docker’s warnings (and I would think users expect and demand abundance of caution). But what happens if Docker mischecked and sent you a false negative on being compromised? And what happens if a full post-mortem is released detailing gaps in security best practices between what’s Docker does and what you could do yourself?

This may well be a moot point; I think if you really wanted to be sure of what you were including in your code you would pull down tarballs and validate checksums for all dependencies before building on a secure network.
