New World - Reverse Engineering

[SheenBR]

So has anyone already tried to figure out packets, packet encryption for this game? Any interest on trying to emulate it?

I played around in IDA Pro a little bit, tried to find some encryption constants using this plugin (https://github.com/nihilus/IDA_Signsrch) but I can't say that I found out where is the packet encryption.

Its been some years that I don't touch assembly code, might take some time xD

By the way, IDA Pro takes a really long time to analyze new world binary given its size. Only works with IDA Pro 64bit.

Still didn't try wireshark for instance to sniff some packets, even encrypted. Will Easy Anti Cheat get me banned for doing this?

If anyone has interest on trying to figure this out leave a comment here and we can share our discoveries. =D

Happy new year!

Not directly related to packet encryption but surely a nice program. Will check it out for sure, thanks!
