I heard about a flag apple has on some of it's apps that wont allow
any other processes to pause it (to walk through it with a debugger or
anything like this). anyone else heard about this or know how it can
be done?
Since the kernel (Darwin) is Open Source, this seems quite unlikely,
since it would be possible for a technically adept person (of the type
that might want to walk-through an Apple program in a debugger) to
circumvent any measure they might have put in place by replacing the
kernel, or even by using remote debug on the kernel and stepping over
the offending lines of code.
There are techniques you can use to make it harder to run your program
in a debugger, however you will never stop a determined hacker from
breaking in to your code; in the limit, they can just patch your
program to remove your security measures before running it.
Kind regards,
Alastair.
