Any clues ? We need to reverse the audio lib ?
Hi,
I’m investigating the lib audio.so but I don’t understand very good the malicious code. Where can I find doc or lessons to understand this?
im looking for small hint 
I finally managed to get the flag, although I feel I followed a very weird approach.
Just to give a small push to whoever feels up to the task:
- Start looking at the interesting component.
- A rabbit may have dug around. If things don’t quite add up, then you may be already cooked. Get a little step back and check better.
- If you got here safely, time to get your brain fucked. Explore the route to the very end, notice the constraints, then find some values you know for sure. Start putting pieces together, then use all the data to guess the missing values.
About step 3, I know for sure it can be done this way. It may be not the intended way. I’d love for some other solver to give me a sanity check.
