So, this has always bugged me. How do you validate a Docker container? No one wants to pull a laced up container, so there has to be a way one can check. Of course, sticking to original docker containers from Docker Hub would be one method I suppose. Is there some kind of scan one can do? I do this on my Windows computer; scan before installing. Besides looking at code that I would have no idea what is going on, what protocols do you guys use?
If you’re not open to the wan, you’re in decent enough shape.
The bar in your situation is that someone would need to shove a ransomware payload into a JavaScript 0-day for a package in your container without anyone noticing it, you’d have to update your container with it, then visit it with a vulnerable internet-connected computer. It’s not impossible, but a really long, long shot.
