This time we got an application. If we run `strings` on it we can see
```
Usage: %s <username> <password>
~> Verifying.
0n3_W4rM
~> Incorrect username
zLl1ks_d4m_T0g_I
Correct!
Welcome back!
CTF{%s}
```
`zLl1ks_d4m_T0g_I` looks like a flag, but it is reversed. `I_g0T_m4d_sk1lLz` looks much better.
Alternatively we can run the application with gdb and look at the registers before both strcmps and see that the correct username is `0n3_W4rM` and the password is `I_g0T_m4d_sk1lLz`.
Flag: `CTF{I_g0T_m4d_sk1lLz}`
