I wonder. Since there are code snippets that can check to see if an app has been cracked/pirated, perhaps there is a way to inject an overlay serving ads on those who pirated. They can't exactly write a negative review on itunes because you can't rate an app unless you've purchased it.

It's always the same game of cat & mouse with pirates.

Most pirates on iOS are simply using one of the free tool and don't go far beyond that. I have implemented a technique for detecting pirated app and used it now in many apps: since then the piracy rate went down to zero which convinced that most pirates on iOS are simply using a tool and don't know what to do if the app they try to crack fail.

I am sure that a true pirate will find way to bypass my security check but so far after more that a year of implementing my solution in all my released app I didn't find anymore pirated copy.

If anyone is interested to learn what can be done, send me an email.

Are you checking that the Mach-O binary is encrypted? I'm not aware of that being worked around by any of the automated tools (and it an approach that is widely discussed).

[yoda_sl]

That is one of the approach but I combine it with a few other useful ones.

I was wondering about the same thing.. If there was a way to identify the pirated copies, how could one possibly add some advertisements to those apps..

Which would just be circumvented with another jmp.

[pagekalisedown]

True, but the vast majority of pirates wouldn't bother.

It would only take one to make it, the rest would then download that.
