The macOS cracking scene is also much much weaker. It's 1. Mildly harder on a OS level 2. Less popular in countries that produce the most cracks 3. Less popular in general 4. Has an audience that is demonstrably more likely to pay for software 5. Has less strong reverse engineering software. Hopper was awful. Also, I just wanted to say I love your work. I've learned a lot from your blog, your free trial strategies ar…
ida pro has a Mac release

#63What is interesting here is that a signed piece of software can pick up an unsigned dll, execute it, and that execution causes a compromise of the system.
Raymond Chen has a ton of "being on the other side of the airtight hatchway" articles. Most relevant I found: https://devblogs.microsoft.com/oldnewthing/20200420-00/?p=10... Probably in this case the installation of the crack requires admin privileges to modify files in "Program Files" folder. Boom, you've broken the rules ;)

For sure, it’s just a bit more effort to reverse the app binary and find that part of the code. Enough effort to deter most crackers apparently.

The flip side of this is that I've noticed software written solely for macOS/iOS is often more polished than many of the most popular FOSS projects written for Linux.
Obviously I don't have any expectation of software provided for free, but as someone who makes a living developing software I do find it funny how much reticence there is among other developers to pay for high quality software.

I feel like this person is trying to copy Foone's voice but just doesn't get it
Cybersec twitter is just awful. Everything has to be a call out or a dunk on someone/some company. It's all so negative.

I think, as a developer, I value the ability to fix things I don't like. I've done it quite a lot in open source software. Just plant my fix and move on. Steam always felt complete. macOS software often feels closer to completion, though sometimes I do wish I could modify it still. Also, another class is software I trust that I could not do a better job on, like Affinity.
Anyway, I think that's the root of the developer aversion to paying for software.... Well, for me anyway. I wish we had better culture around donating to free software as well.
Re: Reverse engineering a software crack
#68It’s done in a similar way on macOS: a dylib is added to the bundle and an LC_LOAD command is added to the app binary. The dylib is the first thing that runs because of using the constructor attribute, like this: https://notes.alinpanaitiu.com/Injecting%20a%20DYLIB%20into%... The nice thing is that a signed app will refuse to load a dylib that does not have the same signature. So crackers will be forced to change the…
If you're modifying the executable anyway, why not just patch it directly instead of going through these hoops?
The equivalent on Linux would be setting LD_PRELOAD and putting your .so file there. A quick Google search seems to imply that the OSX equivalent is DYLD_INSERT_LIBRARIES but I have no idea how similar they are.

#69All the swearing turned me off. I don't mind cussing and use them myself, but does every tweet need to drop the f bomb?

#70Thanks for sharing, it was interesting, but wow that's a bad format and bad writing.
