Detekt is a Python tool that relies on Yara, Volatility and Winpmem to scan the memory of a running Windows system (currently supporting Windows XP to Windows 8 both 32 and 64 bit and Windows 8.1 32bit).
Detekt tries to detect the presence of pre-defined patterns that have been identified through the course of our research to be unique identifiers that indicate the presence of a given malware running on the computer. Currently it is provided with patterns for:
- FinFisher FinSpy
- HackingTeam RCS
Beware that it is possible that Detekt may not successfully detect the most recent versions of those malware families. Indeed, some of them will likely be updated in response to this release in order to remove or change the patterns that we identified. In addition, there may be existing versions of malware, from these families or from other providers, which are not detected by this tool. If Detekt does not find anything, this unfortunately cannot be considered a clean bill of health.
If you encounter samples of such families that are not successfully detected, please open a ticket. In addition, please let us know if you find instances of false positives.
When compiling the tool on Windows systems, you'll have to install some requirements first, including:
- Python 2.7
- Yara 3.x
- PyQt4
- PyWin32
Make sure that you install the latest available version of these libraries, for the right architecture and the right version of Python. You can download latest version of Yara installers for Windows here https://drive.google.com/folderview?id=0BznOMqZ9f3VUek8yN3VvSGdhRFU&usp=sharing#list In order for Yara to work correctly you will also need to install Visual C++ 2010 Runtime.
Once all requirements are installed on your Windows environment, make sure you clone the full repository and submodules with:
$ git clone --recursive https://github.com/botherder/detekt.git
This will clone also the Volatility and PyInstaller trunks. Copy the whole directory in your Windows environment and launch the make.bat script, which should successfully generate the final executable.
Performance is the main issue with Detekt, and it will need to be improved. Some Yara signatures need to be improved, as currently some of them are not able to detect all existing variants of the respective malware families.
Windows 8.1 64bit is currently not supported because the tool appears to be unable to complete the execution and just goes on forever. This issue needs to be investigated and resolved as soon as possible.
