Official Partial Encryption Discussion

Official discussion thread for Partial Encryption. Please do not post any spoilers or big hints.

Having trouble with this one. Been looking at it Ghidra and vaguely understanding the encryption thats occuring, seems like the output of which is being used as maybe a function address? The description also seems to discourage static analysis, but have been unable to dynamically analyze due to anti debugging features, so I’m a bit lost. Is there really a way to do this without static analysis?

I haven’t had a chance to look at it yet but by the description and what you’ve tried so far, maybe this alternative to static analysis might be worth looking into.

I’ve poked around with some dynamic analysis tools and techniques but nothing is jumping out at me. Any hints on this one?

Some news? Still stuck.

Try to use Ida Debugger and walk through the code. I found the flag by patching, but not the input that generates the flag.
