Dumpster Dive Layer 0

We are given a AWS ECR public gallery link.

Trying to pull from it shows an error where there is no matching manifest for our architecture.

Lets try and check whats the ecpected architecture for the image.

Manually enumerating the docker images, we found the manifest file where they copied the flag
