Dont-you-love-banners

The challenge presented an interesting challenge. The first server was leaking some sensitive information. Using that we log into the second server. Then we answer a couple of basic security questions (free knowledge!!). Finally, we landed onto a script that told us the banner file path. We see a flag.txt in this directory. The hint pointed to using symlinks. So we created a symlink from flag.txt to the banner file. We connect to the first server again and obtain the flag.
