IDA Pro 64 bit 36: A powerful disassembler and a versatile debugger



IDA Pro as a disassembler is capable of creating maps of their execution to show the binary instructions that are actually executed by the processor in a symbolic representation (assembly language). Advanced techniques have been implemented into IDA Pro so that it can generate assembly language source code from machine-executable code and make this complex code more human-readable.

The debugging feature augmented IDA with the dynamic analysis. It supports multiple debugging targets and can handle remote applications. Its cross-platform debugging capability enables instant debugging, easy connection to both local and remote processes and support for 64-bit systems and new connection possibilities.


IDA Pro is a complete integrated development environment. It consists of a very powerful macro-like language (IDC or IDAPython) that can be used to automate simple to medium complexity tasks. Integrations IDA runs on all standard platforms and handles multiple processors. It can also load and disassembles virtually any file format and therefore augment its analysis speed.


Fast Library Identification and Recognition Technology identifies standard function calls for many compilers. This technology allows IDA to recognize standard library functions generated by supported compilers and greatly improves the usability and readability of generated disassemblies.


There were some debuggers which could be used for disassembly but they did not really offer RE features such as custom names or comments so deep RE was often done in a text editor or by marking up printouts.


As we all know, disassemblers did not (yet?) get obsolete. Most of the planned features did get added to IDA eventually, not in the least thanks to the users who supported IDA during the early years and spread word about IDA, but also thanks to the early distributorsand supporters such as DataRescue.


When I discovered IDA, it was $30. I knew how to recognize a good deal and walked to my bank in the middle of the night to drop the wire order in their mailbox (pre-internet age stuff). Very very few, an unbelievably small number of people, did the same thing at that time.

I use IDA Pro 6.8.150428 (idaq64.exe) to disassemble system dlls (64 bit) e.g. ntdll.dll, kernel32.dll, etc. in Windows 10 64 bit. I found idaq64.exe correctly disassembling 64 bit sample applications (.exe) but generating incorrect dis-assembly for the dlls e.g. shows 32 bit register operands, etc. I checked the IDA Pro dis-assembly output with WinDbg (runtime) and Intel XED (static) output. While Windbg and XED outputs are consistent with each other, they are completely different than that of IDA Pro.


The static address in the ntdll.dll binary corresponding to the runtime address mentioned above (7ffda61c12e0) is 4b2c12e0. I even don't see the address in ntdll.dll dis-assembly in IDA Pro. It shows:


To do that, you need to use the IDA X.X/dbgsrv/win64_remotex64.exe file and start a debugger. Once the debugger is running, you can connect to it "remotely" and debug. You can check this tutorial for more specific details.


in this case it's the location of win64_remotex64 or remote debugger and nh8sy261 is just some random password. You pick it. Make sure though not to put any spaces after the -P parameter and the password.


(4) Pick Go to work on your own. Then in the blank IDA Pro window, in the menu go to Debugger -> Run -> Remote Windows debugger. Then in the Application pick your application with the ... button. Specify debuggee parameters and directory, if needed. Then in the Hostname add 127.0.0.1, port as 23946 and password as what you typed above in the batch file:

okay so im trying to install origin and the sims4 for my mom on this Dell inspiron 15 that shes had for years. i completely factory reset it and now that ive tried to install it gives me this message "MSVCP140.dll is missing from your computer. Try reinstalling to fix the problem." ive tried reinstalling, then going in as an admin and enabling it and nothing. ive tried uninstalling the entire graphics pack and redoing it and nothing. ive even tried scaning as an admin. im like a 2/10 when it comes to knowing what im doing with computers, so this is all from research on different forums and i still cant get anything to work. this is day 5 and i leave for college next week and i was hoping to have this done by then. can someone please help me.


this is also something i have tried, and its just not registering. after going into my control panel i saw that i have 10 different C++ runtime programs installed but again i have very little experience with computers so i didnt know if uninstaling them all and starting fresh would screw it up or not. ive tried about everything on this page -to-fix-msvcp140-dll-is-missing-error-on-windows/


Thank you for making that clear, i installed the 64x one and still had the issue i will try again. I have downloaded the 86x, its working now. thanks the most for making it clear. Bruh now its saying i have something else not installed


I had the same problem trying to install an EA game (Unravel) on Steam. I installed both versions x86 and x64 and after that the Origin app installed flawlessly and I could continue with installing the game. Thank you for this solution.


This. I have had the same problem as Breelee and it always was missing that DLL but msvcruntime msvcruntime140.dll). I did not know that you needed to have both 32 bits and 64 bits installed. And now I think of it it has sense; most applications are structured for 32 bits.


The FireEye Labs Advanced Reverse Engineering (FLARE) Team is dedicated to sharing knowledge and tools with the community. We started with the release of the FLARE On Challenge in early July where thousands of reverse engineers and security enthusiasts participated. Stay tuned for a write-up of the challenge solutions in an upcoming blog post.


Reverse engineers are likely more accustomed to strings that are a consecutive sequence of human-readable characters in the file, as shown in Figure 3. IDA generally does a good job of cross-referencing these strings in code as can be seen in Figure 4.


Manually constructed strings like in Figure 1 are often seen in malware. The bytes that make up the strings are stored within the actual instructions rather than a traditional consecutive sequence of bytes. Simple static analysis with tools such as strings cannot detect these strings. The code in Figure 5, used to create the challenge disassembly, shows how easy it is for a malware author to use this technique.


Automating the recovery of these strings during malware analysis is simple if the compiler follows a basic pattern. A quick examination of the disassembly in Figure 1 could lead you to write a script that searches for mov instructions that begin with the opcodes C6 45 and then extract the stack offset and character bytes. Modern compilers with optimizations enabled often complicate matters as they may:


Figure 6 shows the disassembly of the same source code that was compiled with optimizations enabled. This caused the compiler to load some of the frequently occurring characters in registers to reduce the size of the resulting assembly. Extra instructions are required to load the registers with a value like the 2-byte mov instruction at 0040115A, but using these registers requires only a 4-byte mov instruction like at 0040117D. The mov instructions that contain hard-coded byte values are 5-bytes, such as at 0040118F.


Clone the git repository at our Github page. The python\stackstring.py file is the IDA Python script that contains the plug-in logic. This can either be copied to your %IDADIR%\python directory, or it can be in any directory found in your PYTHONPATH. The plugins\stackstrings_plugin.py file must be copied to the %IDADIR%\plugins directory.
