Windbg2ida lets you dump each step in Windbg then shows these steps in IDA Windbg2ida - Windbg and IDA plugin
Windbg2ida lets you dump each step (instruction) in Windbg then give you a dump file and you can use it later in your IDA to put color on each line of the instructions that you've run to show code coverage.
You can use Windbg2ida to see differences between two or more code coverages in IDA.
Download windbg2ida from here or use git to download files.
git clone https://github.com/SinaKarvandi/windbg2ida.git
Open Windbg and load windbg2ida.js script (replace path with your computer path to windbg2ida.js)
.load jsprovider.dll
.scriptload "C:\\Users\\Sina\\Desktop\\windbg2ida\\windbg2ida.js"
Important note : If you can't load the script or the script gives you error about using files then make sure to update you windbg (Windows SDK) to the latest version as the previous versions have problem with using file with JavaScript.
- The simplest example is execute until the return of current function. (replace the path to save the dump)
!windbg2ida\_run\_until\_ret "c:\\\\users\\\\sina\\\\desktop\\\\dump1.w2i"
- If you wanna run a specific number of instructions (e.g 100 instruction). (replace the path to save the dump)
!windbg2ida\_run\_with\_limitation 100,"c:\\\\users\\\\sina\\\\desktop\\\\dump1.w2i"
- If you want to execute until a specific address is executed. (replace the path to save the dump and the address(es))
!windbg2ida\_run\_until\_address "fffff80617bc4622,fffff80617bc4628,fffff80617bc462a" ,"c:\\\\users\\\\sina\\\\desktop\\\\dump1.w2i"
- If you want to execute until a specific address is executed or if windbg reaches to the return of current function. (replace the path to save the dump and the address(es))
!windbg2ida\_run\_until\_address\_or\_return "fffff80617bc4622","c:\\\\users\\\\sina\\\\desktop\\\\dump1.w2i"
Now in order to use your dump file(s), copy them into "w2i Files" folder next to IDAScript.py, goto IDA > File > Script file... > select IDAScript.py.
Each time you run IDAScript.py all the .w2i files in the "w2i Files" graphs are colorized in IDA. You can see "Output Window" for more details (e.g functions that changed their colors).
- Change the color of code coverage graph. (Change the hex number of color). This option is special useful when you want to compare two or more dumps.
!windbg2ida\_set\_color 0x36AC29
- Disable Step in into function calls.
!windbg2ida\_disable\_stepin
- Disable registers in comment of IDA.
!windbg2ida\_disable\_registers\_in\_comment
For more information about other configs use the !windbg2ida to see the help.
To unload the windbg2ida.js (replace path with your computer path to windbg2ida.js)
.scriptunload "C:\\Users\\Sina\\Desktop\\windbg2ida\\windbg2ida.js"

These commands show how you can use Windbg2IDA.

run 100 instructions and save the results into c:\users\sina\desktop\dump1.w2i
- !windbg2ida_run_until_address [Address(es)],[FileToSaveDump]

e.g : !windbg2ida_run_until_address "fffff80617bc4622,fffff80617bc4628,fffff80617bc462a","c:\\users\\sina\\desktop\\dump1.w2i"
run until the program reaches to fffff80617bc4622 or fffff80617bc4628 or fffff80617bc462a
then save the dump into c:\users\sina\desktop\dump1.w2i
- !windbg2ida_run_until_address_or_return [Address(es)],[FileToSaveDump]
Description : Run until the program reaches to the specific address(es) or reaches to the return of the current function.
+ [FileToSaveDump] : The path to save the dump which can be use later by IDA.
+ [Address(es)] : Address(es) to stop execution.
e.g : !windbg2ida_run_until_address_or_return "fffff80617bc4622","c:\\users\\sina\\desktop\\dump1.w2i"
