In the below example, we see a call to CoCreateInstance at offset 0x401022:Ĭlsid is Internet Explorer (see details) and rrid corresponds to the IWebBrowser2 interface:īut if we want to know what function is called, we have to add the structure. There are cases where you will need to add a standard structure. Once this modification applied, back to the IDA-View, we can see that the Buffer is now properly labeled:Īdd a standard structure Example 1: IWebBrowser2 To fix that, press Ctrl + K or go to Edit > Functions > Stack variables, right click on the first byte of buffer and select "array" from the menu:Įnter 512 in the Array size field and click OK. In the below example, IDA did not realize that the size of the buffer is 512 bytes and displayed a local variable labeled var_20C instead: There are cases where IDA will fail interpreting the size of a variable and you will need to fix the stack. Now, let's open IDA Pro and go to Debugger > Run > Remote Linux debugger: P password -v verbose Client configuration IDA Linux 64-bit remote debug server(ST) v1.14. Hence, we will copy linux_server圆4 to the remote host. Wince_remote.dll Windows CE 32-bit PE files Win64_remote圆4.exe MS Windows 64-bit 64-bit PE files Win32_remote.exe MS Windows 32-bit 32-bit PE files Mac_server圆4 Mac OS X 64-bit Mach-O files Linux_server圆4 Linux 64-bit 64-bit ELF files Linux_server Linux 32-bit 32-bit ELF files To do that, go to your IDA installation folder and find the appropriate debugger that will run on the remote server:įile name Target system Debugged programsĪndroid_server ARM Android 32-bit ELF filesĪrmlinux_server ARM Linux 32-bit ELF filesĪrmuclinux_server ARM UCLinux 32-bit ELF files debug a remote ELF running on Linux, from IDA Pro, installed on a Windows virtual machine). There are situations where you would find useful to use the IDA remote debugger (e.g. In order that the function is properly displayed in IDA-Pro, press C to convert the byte to CODE: Place your cursor at offset 0x401215, start the python script ( File > Script file.). Then place the cursor at location 0x401216 and press C to convert the block to CODE. Place the cursor at offset 0x401215 and press D to convert the block to DATA. Given the below extract, we see at location 0x401215 a jump to itself: CompileLine ( 'static n_key() ' ) AddHotkey ( "Alt-N", "n_key" ) def nopIt (): start = ScreenEA () end = NextHead ( start ) for ea in range ( start, end ): PatchByte ( ea, 0x90 ) Jump ( end ) Refresh () Here is the result once the option applied: If you want to display opcodes along with the assembly, go to Options > General and fill in the "Number of opcode bytes" as follows:
