<nowiki>The radare project aims to provide a complete unix-like toolchain for working with binary files. It currently provides a set of tools to work with x86, arm and java with some ones powerpc.

The core is a raw hexadecimal editor for commandline with scripting features and perl/python extensions that gets extended with IO plugins that hooks the open/read/write/close/system calls.

The debugger and disassembler has a code analysis module for x86, mips, arm and java. This way it's possible to draw graphs using Cairo on a GTK window or store the flow execution of a program on a log file and use the information to diff't against another trace or binary.

The toolchain provides assemblers and disasemblers for x86, arm, mips (Loongson2F), sparc, CSR, m68k, powerpc, msil and java.

The disassembler has been enhaced to handle inline comments, code block detections and flag references (data pointers or so).

The debugger is mainly developed on linux and {Net

Listed in categories: File System Diff Tools, Registry Diff Tools, System Diff Tools

Most recent version:
5.4.2

Most recent release date:
June 15, 2009

Description:
Total Uninstall is a complete uninstaller which includes two working modes.

Installed Programs module analyze existing installations and create a log with installation changes. It can uninstall programs even without the help of the supplied Add Remove program.
Just select from the list the program that you want to uninstall and in a few seconds Total Uninstall will analyze it and will show in a tree view detected files, folders, registry keys and values of that program. You can review the details and remove some of the detected items. Total Uninstall is ready to uninstall the analyzed program. It will use first the supplied Add Remove program and will continue removing remaining items using the log.

Monitored Programs module helps to monitor any changes made to your system during the installation of a new program. It allows you to perform a complete uninstall without having to rely on the supplied Add Remove program, which can leave files or changes behind.
Total Uninstall creates a snapshot of your system prior to installing a new program. It then takes an additional snapshot after the installation has completed. It then compares the two snapshots and displays all changes in a graphical tree view, marking all registry values and/or files that have been added, changed or deleted. Total Uninstall saves these changes and, if you decide to uninstall the program, it will reverse the changes to the previous state.
Features

* Accurate analyze existing installations and create a log with installation changes.
* Monitor changes from registry and file system for new installations.
* Uninstall completely and thoroughly analyzed or monitored programs.
* List without delay installed or monitored programs and with appropriate icons.

Tool Added: Buster Sandbox Analyzer

2009-12-07T01:55:12Z

Listed in categories: File Monitoring Tools, File System Diff Tools, Network Monitoring Tools, Registry Diff Tools, Registry Monitoring Tools, X86 Sandboxes

Most recent version:
1.03

Most recent release date:
December 07, 2009

Description:
Buster Sandbox Analyzer is a tool that has been designed to analyze the behaviour of sandboxed processes and the changes made to system and then evaluate if they are malware suspicious.

The changes made to system can be of several types: file system changes, registry changes and port changes.

A file system change happens when a file is created, deleted or modified. Depending of what type of file has been created (executable, library, javascript, batch, etc) and where was created (what folder) we will be able to get valuable information.

Registry changes are those changes made to Windows registry. In this case we will be able to get valuable information from the modified value keys and the new created or deleted registry keys.

Port changes are produced when a connection is done outside, to other computers, or a port is opened locally and this port starts listening for incoming connections.

From all these changes we will obtain necessary information to evaluate the "risk" of some of the actions taken by sandboxed applications.

Watching all these operations in an easy and safe manner is possible thanks to Sandboxie (http://sandboxie.com), an excellent tool created by Ronen Tzur.

Even if Buster Sandbox Analyzer´s main goal is to consider if sandboxed processes have a malware behaviour, the tool can be used also to simply obtain a list of changes made to system, so if you install a software you will know exactly what installs and where.

Additionally apart of system changes we can consider other actions as malware suspicious: keyboard logging, end the Windows session, load a driver, start a service, connect to Internet, etc.

All the above operations can be considered as not malicious but if they are performed when it´s not expected, that´s something we must take in consideration. Therefore it´s not only important to consider what actions are performed. It´s also important to consider if it´s reasonable certain actions are performed.

Tool Added: DarunGrim

2009-02-09T12:36:06Z

Listed in categories: Executable Diff Tools

Most recent version:
2.0

Most recent release date:
February 7, 2009

Description:
DarunGrim is a binary diffing tool. DarunGrim is a free diffing tool which provides binary diffing functionality.

Binary diffing is a powerful technique to reverse-engineer patches released by software vendors like Microsoft. Especially by analyzing security patches you can dig into the details of the vulnerabilities it's fixing. You can use that information to learn what causes software break. Also that information can help you write some protection codes for those specific vulnerabilities. It's also used to write 1-day exploits by malware writers or security researchers.

This binary diffing technique is especially useful for Microsoft binaries. Not like other vendors they are releasing patch regularly and the patched vulnerabilities are relatively concentrated in small areas in the code. That makes the patched part more visible and apparent to the patch analyzers. There is a "eEye Binary Diffing Suites" released back in 2006 and it's widely used by security researchers to identify vulnerabilities. Even though it's free and opensource, it's powerful enough to be used for that vulnerabilities hunting purpose. Now I'm releasing DarunGrim2 which is a C++ port of original python codes. DarunGrim2 is way faster than original DarunGrim.

Tool Added: Compare VMware Snapshots

2008-04-28T10:59:15Z

Listed in categories: File System Diff Tools

Most recent version:
1.0

Most recent release date:
September 19, 2007

Description:
Nowadays there’s a big use of virtualization; tools like VMware, VirtualPC and others are daily used. There are some differencies between the original and the virtualized environment, but to study a malware under a protected blackbox it’s very comfortable. You can study their behaviour without any problems.

Just today, while I was running a malware, I got this foolish idea: can I identify hidden files using VMware’s snapshots?

Under VMware you can save the current state of a virtual machine taking a snapshot of the running guest system. The snapshot is stored somewhere in the guest’s OS folder, it simply needs some files. I’m interestered in one file only, the one containing the guest’s memory. The memory is saved inside a file with .vmem extension.

The idea is to take two snapshots (a virgin and an infected system), and then compare the two files. The main problem is that a single snapshot needs a large amounts of bytes, around 260 Mb on my system. Comparing the snapshots using an hex editor is madness. I decided to write a simple application able to compare two files string to string. Why only strings?
Well, how can I identify an hidden file simply looking at a “memory dump”? The answer is simple: the only thing able to reveal a trace is a string containing the name of the hidden file, nothing more. So, I extract all the strings from the virgin snapshot and then I compare them with all the strings from the infected snapshot. Yes, it’s a foolish idea but it helps me to pass a boring afternoon.

The most important part of the program is the internal “search engine”. To speed up the program you have to search for specific strings. To view the results in a quick way I simply search for strings with extension “.sys”, “.dll” or just “.exe”. That’s because these are the file extensions of the files that are always hidden. You can improve the search engine adding some more rules (i.e. string must have “system32″ or “windows” inside) but the result won’t change: you can always see some interesting strings.

I tried the program running two malwares: Lager and Nailuj.
Lager malware hides a file named taskdir.exe and Nailuj hides videoati0.sys/dll/exe.
In both cases, I can see some strings referring to the hidden files.

The string is somewhere in the memory, I’m not interested in its position but in the string itself: it exists!

There are some good tools out there able to show hidden files but sometimes they fail. When they fail you can try with this approach.

Description:
pynary will become a powerful platform independent framework for binary code analysis.

The initial goal is to the implementation of function signature matching using graph isomorphism and an extensible 'write-your-own-heuristic' model to allow tweaks for particular targets. It will also identify standard library global constants and structure where possible.

Once the initial goal is achieved, a number of cool features are planned:

* stack frame analysis
* un-inliner
* exception handling parsing/analysis
* 'functionally equivalent' matching
* c++ template function matching
* meta-data transfer between IDBs
* c++ class reconstruction (with/without RTTI)
* ...

This project is still in its infancy, and looking for volunteers.
