Hi.

I am going through my first steps in Linux RCE, and before I go in a wild geese chase, I would like to ask more experienced people the viability of my approach.

I have a commercial app that is available for both Win and Linux plataforms.

I have much more experience dealing with Win RCE, so I thought analysing the protection in Win would give me the heads up when dealing with the protection in Linux.

So far, I have not made much progress, but in your opinion and experience,
How common/likely it is that the protection location, code, and implementation would be similar between the two plataforms?

Or am I just working twice here?

Well, I think that the protection per se will be NOT the same, mostly due to the substantial differences between the two OSs. So you could directly attack LINUX target...

Also for recovering source code I would directly start on Linux... IDA Pro does a great job on it!

Just my 2c

check both the windows and linux version to see if they have debug symbols (and/or optimisations etc).. more often than not people slip up and include debug symbols in one, it usually depends if they're mainly a windows shop.

If they're both equal, go for what you know best if you want to do a quick job of it, if you wanna expland your horizons, go for the other.
