Now, from prior knowledge, names can be leaked if you don’t hide them while doing commits. So, instead of going through all the commits, I thought “why not just use the API and query the repo and the username?”

curl -H "Accept: application/vnd.github+json" https://api.github.com/repos/starknight1337/rustlings_practice/events

Rustlings_practice is the repo that starknight1337 owns

application/vnd.github+json is needed to query githubs api as it is a custom media type

Running this, we are presented with:

There is the name! And our flag!
