![]() Later, when I looked at the logic and found that it was a dead end, I took a closer look at the call statement. At first I thought the function it jumped to must be a registration-related function, and jumped to xref and directly named the variable. Note that you cannot use the x key to directly search for a reference to this string. Very intuitive.~~ Although the CFString string references introduced by Obj-C in the decompiled code are too blind to read… but it is still very useful!~~ ![]() Say a little bit about IDA here, all string names are automatically named as names related to string content such as. Double-click to enter the disassembly window to find data references here. Bind the function above it must be a key function related to registration. Think about the MVC that you learned in your sophomore year, and you also know that this is a button event, or a registered button. Shift-F12 Open the IDA string window, Ctrl-F Search register and accidentally find an important thing Find the real executable of the software under. The software downloaded from the official website is an S urge.app folder, the folder named is how OS X software is organized. Actual combat is the baby’s favorite ho ho ho The software selected here is Surge, the famous “network acceleration tool” under OS X. The following will describe two ways to bypass signatures, this is one of them. Digital signatures are available in almost all programs under mac. Unsign (optional) Anonymous god’s gadget to forcibly remove program signatures.Have a unique understanding of Obj-C, after all, fashionable The disassembler software under Hopper Disassembler OS X, just download the trial version.Common sense, the registration button is register in English, activation is called activate, being caught is revoked, and so on.C language, you need to have a certain understanding, after all, the disassembly results are presented in the form of pseudo-C language.X86 assembly, there should always be a little bit.After all, as a tool kid, using tools is one~~ big~~ half of success. Briefly explain the knowledge (tao) knowledge (lu) and gadgets needed to crack an OSX (um… it will be called macOS soon) program. □įor Chinese version of this article, see here. To get back (when he has time) and revise these articles. Ida pro will be your best friend: You will need to get comfortable with assembly language and the instruction set of the micro in the device you are trying to reverse engineer.Īnd if you wants to use some paid tool then Binary Ninja & IDA Pro is best for you.This article is machine translated which hasn’t been proofreaded by the author. ![]() ![]() Getting started with automotive controller reverse engineering, are there any good resources? Yeah, that sounds plausible, you might take a look at Ghidra as an open source/free alternative to IDA Pro.
