It’s been some time since I’ve done some Reverse Engineering and today I’ve completed a simple challenge on https://www.root-me.org/. The filename of the challenge is crackme_wtf and here are some hints to get you started:
- Determine type of FILEs.
- Don’t be afraid to patch and use a debugger.
- Try to eliminate the randomness. Maybe some functions that have to do with time, random numbers or the current process’s id.
- If the last hint doesn’t yield any results… Is the required password really needed to get to the flag?
Thanks for reading and good luck!
