Nice challenge. For me it was:
ltrace + patching + xor bruting = flag
Hi people,
I have performed a hidden function. after which I got a long string with a repeating “f” character. I lack my knowledge to get a complete understanding of the password conversion algorithm. the only thing I see is the ‘xor’ in the hidden function, but I don’t know how to use it, since the loop in the hidden function confuses me.
Who in personal correspondence can help me figure out the password conversion algorithm, as well as your method of getting the flag?
I will also be glad to any hints in this chat.
thank you in advance
Am I allowed to post a solution here since the challenge is retired? I made a video on YouTube but I don’t want to link it unless that would be acceptable
