Hopper Disassembler V3 Keygen Free
Itxaso Mariyo
I have recently been playing with Hopper, a disassembler for Mac OS X, quite a bit. The tool is essentially a mid-line tool for working to reverse engineer code. It is more accessible on the mac than firing up a VM and using the venerable OllyDbg and the interface is quite a bit more elegant and user friendly. It is even mid-line in price, coming in between Olly, which is free, and IDA Pro which can run over a thousand dollars per license. If you hack stuff, reverse stuff or study malware on the Mac, the $60 price point is likely to make this a big winner for your budget. The app store link for the tool, in case you want to check it out, is here.
Lastly, I would like to thank the author of Hopper, Vincent Benony for his work on this tool and for his engagement with the infosec community on Twitter. Seriously, he is great. He responds quickly to questions and requests, plus provides great insights into where he is taking the product next.
The only line I sort of understand here is setting a variable to 0x5. I'm unable to comprehend what all these additional lines are for (such as the rsp = rsp + 0x8;), for such a simple program. Would anyone be willing to explain this to me?
In this case it looks like it has has elided the stack frame setup (the function prolog), but not the cleanup (function epilog). So you'll get a much better idea of what is going on by using an actual disassembler to look at the actual disassembly code:
In the case of your disassembly, the first part has been elided (left out as being an uninteresting housekeeping task) by the disassembler, but the second to last part (which undoes the first part) has not.
What you're looking at is decompiled code. Every decompiler ouptutwill look something close to that because it's not going to try and get variable names because they can be changed so often and usually are.
So it will put them in a 'var_??' with a number attached to the end. Once you learn about reverse engineering and know the language you're programming in very well, you can understand the code. It's no different when you're trying to de-obfuscate PHP, JavaScript code, etc.
If you ever get into reverse engineering malware be prepared because nothing is going to be easy. You're going to have different packers, obfuscators, messed-up code, VM detection routines, etc. So buckle down and get ready for a long road ahead if reverse engineering is your goal.
Depending on your build configuration this could be part of the debug info, or coverage data. Depending on the code in the module it could also be because of function calls that include #file as an argument for error messages
In hopper what are the references pointing to the strings? (In your screenshot sub_10007ed30+236 for example). Also what section of the binary are they in (should show in the bottom left of hopper if you're selected where your screenshot is)
Seems like the file name string literals come from fatalError calls which would make sense as fatalError defines #file as a default argument fatalError(_:file:line:) Apple Developer Documentation. Will try out a version with all fatalError calls removed.
Hopper Disassembler is a binary disassembler, decompiler, and debugger for 32-bit and 64-bit executables. It will let you disassemble any binary you want, and provide you all the information about its content, like imported symbols, or the control flow graph! Hopper can retrieve procedural information about the disassembled code like the stack variables, and lets you name all the objects you want.
Hopper is able to transform the assembly language into a pseudo-code that is easier to understand! You can use its internal Python scripting engine to analyze binaries the way you want (this feature works only with Lion)! Starting from version 2.0, Hopper can even use GDB to debug programs!
Hey guys, I'm a big fan of the hopper disassembler. Unfortunately qt5-enginio is required as an dependency, which is no longer available on the arch repos. Is there any way I can still obtain qt5-enginio. I've been trying to find the source for qt5-enginio, tough didn't find too much.
Here's potentially a better solution. I put together a script to download the official package and patch the PKGINFO to remove all of its unnecessary depends. It generates a new package file ready for checking and installation.
