## Solution
|
|
|
|
When taking a look at the source we find the following comment:
|
|
|
|
```html
|
|
<!-- This is an odd encoded thing right? YWR2ZW50X29mX2N0Zl9pc19oZXJl -->
|
|
```
|
|
|
|
If we then use `base64` to decode this string we get `advent_of_ctf_is_here`.
|
|
|
|
```bash
|
|
> echo "YWR2ZW50X29mX2N0Zl9pc19oZXJl" | base64 -d
|
|
advent_of_ctf_is_here
|
|
```
|
|
|
|
We can then enter this string on the challenge website after which it will give us the flag: `NOVI{L3T_7H3_M0NTH_0F_FUN_START}`.
|
|
|
|
This flag can then be submitted for the [challenge](https://ctfd.adventofctf.com/challenges#1-2).
