Wow lets do some magic! For this challenge we are presented with an input field a submit button and some kind of comparison in the button. I will go through my thought process instead of going directly to the solution because I think some of the things I did can be used in enumeration in the future.
First I took a look what 0e953532678923638053842468642408 is. I used Hash Analyzer provided by https://www.tunnelsup.com/hash-analyzer/
The result was that this hash is an MD5 or MD4. Because we see the ‘ == ‘ that means that some comparison will be done. After playing with the input I discovered that there is a function called is_numeric() who does the comparison and that it must return false.
Some googling was done and the conclusion was that this is a “magic hash”. Combining this with the previous information gathered I knew that I need a value which when hashed will equal to 0e953532678923638053842468642408. More googling was done and i discovered that the value I need is QLTHNDT. After submitting we get the flag.
The flag for this challenge is: LLS{magic_hashes_make_for_a_good_show}
