![]() I'm assuming that you are using our dear Kali Linux, but this works almost the same way in Windows and Mac OSX. IDA Pro is available for Linux, Mac OSX and Windows, while Hopper is officially available only for Mac OSX and Linux. I'm going to use HxD (supported by wine, the windows emulator) on Linux. The software I'm going to use for the demonstration is Interactive Disassembler, better known as IDA Pro (though I'm going to mention Hopper Disassembler's extremely useful features).įor the tutorial, demo version of IDA is enough, though one part of the article requires a hex editor to save you work (don't worry, I got you covered if you don't have one). So we are mostly talking about Reverse Engineering. The uses are infinite and go from games mods to decrypt obfuscated code, patch security holes, backdooring and iOS applications modding. In some special cases updates may knowingly break the functionality, for instance, by removing components for which the update provider is no longer licensed or disabling a device. This includes fixing security vulnerabilities and other bugs, and improving the usability or performance. Here I'm quoting the definition of "patch" from Wikipedia, evading any eventual misunderstanding:Ī patch is a piece of software designed to update a computer program or its supporting data, to fix or improve it. Some of you probably know what I'm talking about, but might not know how far can we go with binary patching. Today I'm going to talk about binary patching and why this is an important piece of computer knowledge.
