Hi,

As already talked in this thread (and in this thread too), that could be fun if we could have a Cracking or Reverse Engineering section in HT. I hope @flabbyrabbit will agree to add some of these levels, so I propose here a second level to solve (I made it myself), for anyone who’d like to try it. Enjoy! (feedback is welcome)

[i]In this level you'll have to change the value of the variable "htvar" to 1337. Type "check" to check the value of htvar, and type "exit" to quit. Good luck![/i]

You can download the program to crack here.

Hint (for lamerz):

You’ll need some tools, like a Hex editor, a disassembler and/or a debugger!

Feel free to PM me to submit your solutions, although you’ll know when you got it. I hope this level is not too much difficult, I agree it could have been easier for a “level 2”.

it seems that @feuerstein already solved it. In less than 15 mn. Someone else to do better?

Looks like I need to get my hands on it quicker, also is it harder than Cracking Level 1 ?

I have just started looking into cracking level 1 and I cannot find any clue for now, thus level 2 seems easier to me

I think it is. What disasm are you using?

I’m using objdump but this is a random choice and maybe I should be using a real debugger
Actually I solved level 2 with hexedit

Yes you should go for a debugger

I always used IDA, maybe it’s a great opportunity to start using ghidra?
