How exactly "secure" is a container with all capabilities dropped, distroless, with a custom rootfs directory, a static, single binary with chmod set at 100 and file ownership pointed to non-root u...
ser*, and said non-root user being “nonexistant” (i.e set via ENV)? Can such container -STILL- be exploited/breached through malicious means? Forgot to mention that its a DOCKER container @ title, but there you have it. Just curious.
These are exploited by malicious processes doing something to the hardware which may result in information about your process(es) being leaked. Now, if this is on your computer, then the chances of encountering a malicious process that exploits this hardware bug would be low.
However, when you move this scenario to the cloud, things become more possible. Your vm/container is being scheduled on CPUs that may/may not be shared by other containers. All it would take is for a malicious guest VM to be scheduled on the same core/CPU as you and try exploiting the same hardware you’re sharing.
