Just a heads up to let you know that I have migrated this site to it’s new home at finnian.io/blog. New content will be posted there but I am keeping this one live for historical reasons.
Do you use git to manage your site and or server files? In my opinion, this is undoubtably a good way to run things but you need to make sure it’s secure. Just try going to yoursite.com/.git/config. If you haven’t secured your server properly, you will see the configuration file for your git repository. Not good, huh? Not only could an attacker reveal lots of information about your code base including where the upstream server is, I believe they could possibly get the entire source. This would allow the attacker to see exactly how the site works and be able to exploit it very easily.
Now, the good news. It’s an easy fix!
