But do you know you can still use any of your favorite Android or iOS apps on your laptop even if the official version for PC platform not available? Yes, they do exits a few simple tricks you can use to install Android apps on Windows machine and use them as you use on Android smartphones. Most of the apps available on Google play store or iOS Appstore are made exclusively for mobile platforms. Keep reading this article to get to know how you can Download and Install one of the best Tools App Dev Utils for PC. Try to program the licensing mechanism for your app in pure C, that will already make it harder for me to find my way around your binary.Looking for a way to Download Dev Utils for Windows 10/8/7 PC? You are in the correct place then. Objective-C makes it really easy to mess with an app's internals. Quit gdb and relaunch the app from the Finder, and bask in your leet glory. $ gdb Exces (gdb) break Breakpoint 1 at 0x4c90 (gdb) r (gdb) disasĪdmire our work: 0x00004c9c : jne 0x4ca7 D$.K$.t.EĬonvert it back to binary form, then save and quit: :%!xxd -r :wqĪnd… We're done! To check our work, launch the app in gdb, break to and disassemble.

Now that we have our beautiful hex code loaded up, let's search for the first two bytes of our code to replace: /7409 Drunk Kernel programmers probably thought it'd be funny. Incidentally, every Mach-O binary starts with the hex bytes cafebabe. Following it are 16 bytes, broken off in two-byte segments. The first part, before the colon, is the address of block. This loads up the binary as ascii text, which is of little help. I used vim, but feel free to use any hex editor at this point.

The very first byte of the series is the 74 that we switched into 75. That's the memory representation of the code, a whole 8 blocks of four bytes starting at 0x00004c9c. Let's find a chunk of our edited binary big enough that it likely won't be repeated in the whole binary. We need to edit the code on disk, in the actual binary file. As it currently stands, everything will be erased as soon as we quit gdb. We still need to make our change permanent. Time to get wasted and party! (I recommend Vessel nightclub in downtown San Francisco.) Well, not quite.
Woot! Victory! We're in, and the app thinks we're a legitimate customer. Hooray! This looks good! Let's execute the app to admire our crack. $ cd Exces.app/Contents/MacOS $ class-dump Exces | vimīrowse around, and find the following gem: SSExcesAppController : NSObject 0x00004c9d=0x09Īnd check again… 0x00004c9c : jne 0x4ca7 The first step is to poke into the target app's headers, gentlemanly left intact by the unwitting developer. $ sudo brew install otx $ sudo brew install class-dump If you prefer GUIs, feel free to use your code editor of choice, HexFiend and otx's GUI app. Note that I will use command line utilities only, including vim. I like to use Homebrew as my package manager of choice. Let's start by making sure we have the two utilities we need: otx and class-dump. I chose Exces, a shareware App I wrote a long time ago. And, lastly, you're going to need an app to operate on. You're going to need the Xcode tools installed. In order to follow along you're going to need a few command line utilities. I'll be ending this article with some tips to prevent this kind of hack. By walking through how I can hack your app with only one Terminal shell, I hope to shed some light on how this is most commonly done, and hopefully convince you to protect yourself against me. Well, not you specifically, but by you I mean the average Mac developer. However, I do not believe that obscurity and ignoring the problem is an acceptable solution. Some will view this article as an endorsement of piracy, but rest assured that it is not.

DEVUTILS MAC HOW TO
Here's how it can be done and how to prevent it. While the Mac is rarely targeted for security exploits and viruses, it's no stranger to software piracy-likely because Mac apps are pretty easy to crack.
