IDA is powerful Debugger/Dis-assembler, you can read more in this The main road block for the installation is that IDA is a 32 bit application and so expects 32 bit libraries. But your system being 64 bit will only have 64 bit libraries and so you have to install the 32 bit variant of the libraries that IDA requires. I will walk you through the install steps. Step 1: Download Download the IDA filesl, of course it's a paid software and you can get only the demo version.
Step 2: Unzip Unzip the files and try to run the executable ' idaq' #./idaq and if your Ubuntu is 64 bit something similar may show up./idaq: error while loading shared libraries: libgthread-2.0.so.0: cannot open shared object file: No such file or directory Step 3: Install 32 bit libraries So you have to install the 32 bit libraries, 64 bit version will be already present on your system by default. Find the package that has libgthread-2.0.so.0 # dpkg -S libgthread-2.0.so.0 libglib2.0-0:amd64: /usr/lib/x8664-linux-gnu/libgthread-2.0.so.0 The package name ' libglib2.0-0:amd64' and 32 bit package will be ' libglib2.0-0:i386' And install the package ' libglib2.0-0:i386' #apt-get install libglib2.0-0:i386 Before trying to run IDA again you can find out all the libraries that are not found in the system using the below command #ldd idaq grep found After installing all the missing libraries you can run IDA again./idaq.
In this tutorial, I cover how to Install IDA Stealth. I also talk about what you can do if the plugin isn't automatically detected and loaded by IDA.
This technique will also apply to all IDA plugins such as PatchDiff2. Buy IDA The Interactive DisAssembler: Download the IDA Stealth plugin: The IDA Disassembler and Debugger is an interactive, programmable, extendible, multi-processor disassembler hosted on Windows, Linux, or Mac OS X.
Race 2 full movie hindi free download dvdrip. IDA has become the de-facto standard for the analysis of hostile code, vulnerability research and COTS validation.
Contents. Description and installation Description IDA is a Windows, Linux or Mac OS X hosted multi-processor disassembler and debugger. Installation Flavors. Recommended installation It is recommended to install Python 2.7 first and then IDA Pro to avoid errors with PySide.QtGui. Install IDA Pro.

When prompted, check 'Install python 2.7'. It will ensure python will be supported by IDA Pro. To install plugins, refer to. Usage Display opcodes If you want to display opcodes along with the assembly, go to Options General and fill in the 'Number of opcode bytes' as follows: Here is the result once the option applied: Patching Patch code from IDA. Before you patch the file, make sure you have a copy of the initial file so that you can compare or rollback.
You can patch an executable from IDA Pro directly. Go to the location you want to patch, right click and make sure Hex view is synchronized: From the IDA View, click on the instruction to modify and go to the Hex view.
Right click on the byte to modify and select 'Edit' from the menu: Make your modification, right click on the byte and select 'Commit changes' or press F2. Now, go to File Produce File Create DIF file: Download idadif.py and run it as follows: C: tools idadif.py e7bc5d2c0cf44196561297.patched.2 e7bc5d2c0cf44196561297.patched.dif Patching file 'e7bc5d2c0cf44196561297.patched.2' with 'e7bc5d2c0cf44196561297.patched.dif' Done. You can also use idapatcher.c from the IDA Book, but you will need to compile it. You can check the differences using the utility: C: tools fc /b e7bc5d2c0cf44196561297.init e7bc5d2c0cf44196561297.patched.2 Comparaison des fichiers e7bc5d2c0cf44196561297.init et E7BC5D2C0CF44196561297.PATCHED.2 0001F21C: 74 EB The above output means that 74 has been replaced by EB NOPing out instructions The below python script can help NOPing out instructions in IDA Pro (will apply to the instruction where the cursor is).
It will also bind the script to the Alt+ N key combination. Stack after change Once this modification applied, back to the IDA-View, we can see that the Buffer is now properly labeled: Add a standard structure Example 1: IWebBrowser2 There are cases where you will need to add a standard structure. In the below example, we see a call to at offset 0x401022: clsid is Internet Explorer (see ) and rrid corresponds to the IWebBrowser2 interface: But if we want to know what function is called, we have to add the structure. To do that, go to the Structures tab and press the Insert key. When prompted, enter the structure named, based on the following pattern: InterfaceName Vtbl where InterfaceName is IWebBrowser2 in our case.
In the below code extract, we can see that the reference to the COM object is stored on the stack and moved to EAX at offset 0x40105C. EAX is dereferenced at 0x401065 and EDX points to the beginning of the COM object.
To know what function is called at 0x401074, right click on the offset (0x2C). It appears that it corresponds to the Navigate function: Example 2: ATINFO In the following example (Lab 09-03 from the Practical Malware Analysis book), we have to deal with the ATINFO structure in the DLL3.dll file: In DLL3.dll, go to the Structures window, press the Insert key, and add the ATINFO structure: The DLL3GetStructure function returns a pointer to the dword1000B0A0 global variable which is defined in DllMain: Go to dword1000B0A0 in memory, select Edit Struct var. From the menu, and select the ATINFO structure previously added: Back to DllMain, the code is now much more readable: Load with manual Image base address Manual load In case you're analyzing a DLL that has been, you will need to manually load the DLL into IDA Pro. To do that, ensure the Manual load option is checked when you're loading the DLL: You're then prompted to enter the new address: Rebasing If the malware is already opened in, you can rebase it by going to Edit Segments Rebase program. And specifying a new address. Below is an example of a malicious driver we want to rebase.
The default address is 0x10000 but we know the driver is loaded at the 0xf7be9000 offset. Let's modify the window as follows. After Graphing of several functions To make a graph of several functions, select the functions or a portion of code and select the desired graph type (from, to.). Below is an example. Suppose we want to highlight the relationship between WinINet functions.
Let's select several functions and click 'Xref Graph to'. Add missing cross references There are situations where IDA Pro won't be able to detect all cross references (e.g. Function pointers). To add missing cross references, use python IDC: AddCodeXref( locfrom, locto, flowtype); The three parameters are:. the location the reference is from.
the location the reference is to. flow type: flCF (normal call instruction) or a flJF (jump instruction) Convert bytes to WORDs We have just decrypted a shellcode into IDA-Pro and we have defined the decrypted stub as CODE ( C). However, there are some bytes at the end of the code which are actually DWORDs. They do correspond to shellcode function hashes, as explained: To convert these bytes, let's first define them as individual arrays with a size of 4 (press. on the numpad or right click and select Array): Once this is done, press dd on each of these arrays to convert them to DWORDs: Plugins. IDA Python Scripting List of IDC functions The complete list of IDC functions can be found.
Setcolorssiko.py You can use the following python script to highlight:. Call functions. Non-zeroing XORs (data encoding). sidt, sldt, sgdt, smsw, str, in, cpuid (Anti-VM instructions).
int 3, int 2D, icebp, rdtsc (Anti-Debugging instructions). push/ret combinations (return address abuse) The script is also available. From idautils import. from idc import. #Color the Calls off-white heads = Heads ( SegStart ( ScreenEA ), SegEnd ( ScreenEA )) funcCalls = for i in heads: if GetMnem ( i ) 'call': funcCalls.
Append ( i ) print 'Number of calls:%d '% ( len ( funcCalls )) for i in funcCalls: SetColor ( i, CICITEM, 0xc7fdff ) #Color Anti-VM instructions Red and print their location heads = Heads ( SegStart ( ScreenEA ), SegEnd ( ScreenEA )) antiVM = for i in heads: if ( GetMnem ( i ) 'sidt' or GetMnem ( i ) 'sgdt' or GetMnem ( i ) 'sldt' or GetMnem ( i ) 'smsw' or GetMnem ( i ) 'str' or GetMnem ( i ) 'in' or GetMnem ( i ) 'cpuid' ): antiVM. Append ( i ) print 'Number of potential Anti-VM instructions:%d '% ( len ( antiVM )) for i in antiVM: print 'Anti-VM potential at%x '% i SetColor ( i, CICITEM, 0x0000ff ) #Color non-zeroing out xor instructions Orange heads = Heads ( SegStart ( ScreenEA ), SegEnd ( ScreenEA )) xor = for i in heads: if GetMnem ( i ) 'xor': if ( GetOpnd ( i, 0 )!= GetOpnd ( i, 1 )): xor. Append ( i ) print 'Number of xor:%d '% ( len ( xor )) for i in xor: SetColor ( i, CICITEM, 0x00a5ff ) Decode XOR strings You can use python scripts to decode strings (e.g. XOR'ed) into IDA. Here is an extract of a shellcode that decodes a XOR'ed To decode the XOR'ed stub, we have to patch each byte by XOR'ing with 0x66.
To do that, we can use a custom python script as follows. # decode-xor.py loc = 0x18FD68 # Start offset of XOR'ed stub for i in range ( 0x1DF ): # Loop in range 0x00-0x1DF b = Byte ( loc + i ) # We save each byte in b decodedbyte = b ^ 0x66 # XOR byte with 0x66 PatchByte ( loc + i, decodedbyte ) # Patch each byte with decoded byte Go to File Script file. And select decode-xor.py. IDA will update your code as follows: You can select the entire block and press the A key to display the string: Decode shellcode Description Given the Lab19-01.bin shellcode from the Practical Malware Analysis book. Let's see how we can decode the encrypted part with a python script. First of all, we need to identify the shellcode sections: Section Address range NOP sled 0x00000000 - 0x000001FF Decoding stub 0x00000200 - 0x00000223 Encrypted stub 0x00000224 - 0x000003B0 For more information regarding the identification of the sections, refer to.
The decryption routine is relatively simple to understand. Def shl ( dest, count ): return dest Script file. Arrange code/data Now, we still need to manually arrange the code, using:. U for undefined,. D for data,. C for code,.
A for ascii. Below is the result of the fully decoded shellcode.
Docker IDA Run disassembler in containers. Ideal for automating, scaling and distributing the use of IDAPython scripts to perform large-scale reverse engineering tasks. Our blog: Requirements. Machine with Docker installed. IDA Pro Linux version installation file (.run) and a valid license for running multiple instances. Installation.
Ida Pro Demo
Clone docker-ida repository: $ git clone. Copy IDA Pro installation file to the repository's ida directory: $ cp docker-ida/ida/ida.run. Build IDA docker image: $ sudo docker build -t ida -build-arg IDAPASSWORD= docker-ida/ida Note: It is recommended to push the built image to a private Docker Hub repository.
Otherwise you have to build the image on every machine Start an IDA Service Container IDA service container receives remote IDA commands over HTTP and executes them. To start a container, run this command: $ sudo docker run -v:/shared -p:4000 -it ida -c -t. is a local directory on the host containing the files you want IDA to work with.
Scripts, files to disassemble, etc. Note: If you use on Windows, you might experience some issues parsing paths. Use // in the beginning of the paths (see ).
is the port you tell the host you would like to use to connect to the specific docker container. (see ). is the number of IDA worker processes. This number should be up to 4 workers per core in the host. Default is 8.
is the server timeout for each request. Default is 30.
Note: In order to run multiple containers on the same host, publish each container to a different host port Usage On The server:. Start two IDA containers as daemon: $ sudo docker run -v /path/to/current/folder/docker-ida/examplevolume:/shared -p 4001:4000 -d ida -c 4 $ sudo docker run -v /path/to/current/folder/docker-ida/examplevolume:/shared -p 4002:4000 -d ida -c 4 On The client:. Install idaclient Python library: On Windows: $ pip install 'git+On Linux / Mac OS X: $ pip install 'git+Note: pip version must be 8.1.1 or higher. Send commands to the containers using the Python library. import idaclient client = idaclient.Client( ', ') client.sendcommand( 'idal -Sextractfilefunctions.py -A zlib.dll.sample ', timeout = 600) True files = 'zlib.dll.sample ', 'Win32OpenSSL.sample ' # Building list of commands to send at once commands = 'idal -Sextractfilefunctions.py -A%s '% file for file in files client.sendmultiplecommands(commands, timeout = 600) True, True Advanced Usage. Add additional python libraries to the repository's ida/requirements.txt before building the image.
The library is already installed for rapid IDAPython scripting. For IDA 64 bit files. client.sendcommand( 'idal64 -Sidapythonscript.py -A samplex64.exe ', timeout = 600) True. You can use any of the (except for GUI-related switches) Troubleshooting If the script doesn't run correctly:. Examine the log files in the volume /logs/.
Each container has a different log file named -ida-service.log. Make sure the IDAPython script is Python 2.7 compatible, Python 3.x is not supported in IDAPython. Make sure to add Python libraries to the requirements.txt before building the docker image. When requirements.txt changes, the docker image and containers can always be rebuilt. Make sure the paths to the IDAPython scripts and files to disassemble in the send command are relative to the volume.
Notes. Tested with IDA 6.9. You are required to read the prior to using this project.
