I've been trying to catch him lacking, maybe some poorly written code or something... all I've got is a username: `yattana_yattana`. Don't even know what it's for, can you help me out? Author: `@scuffed` First things first, I ran sherlock on the username and found a few results.

After going through all of them, we find that this leads us to his Twitter account, as confirmed by the account talking about a flag.

After looking through some of their posts, I found an interesting post,

98fCuFS7VA5nepzJBYrN8q2f6LyDVsAynEFnyHQRrygc

Turns out this was a red herring but there were a whole bunch of transactions from this address

After searching some more, I found the correct post, where it was talking about a github repo, (makes more sense since the challenge name is Bad Coder)

By going to the github, we see there is only 1 repo available

After taking a closer look, we see that there are 3 branches, lets take a look at them

I went to take a look at the `testing` branch and there were 11 commits. So I went to take a look at the `Create env` commit, and the flag was there.

Thus giving us the flag `blahaj{c4r3fuL_w17h_y0UR_c0MM175}`.
