Malware Feature Engineering

A one-stop hub for all security machine learning researchers.

About MalFe

The goal of this platform is to bring forth a new stronger data platform that can be used to generate custom datasets that can aid security researchers in building better machine learning models to combact malware. This platform relies on cuckoo reports of analysed malware samples and then gives security researchers the ability to use these reports to build their own datasets, add reports, add public datasets and even use it for private use.

How MalFe Works?

To use MalFe is relatively easy, but requires you to have a knowledge of machine learning and security. The functionality and workflow is presented in the video below:

Popular Datasets

Ransomware_Detection_Using_Features_of_PE_Imports
A dataset of features of the imports of portable executables (PE Imports). The features extracted are: a ratio of the number of functions utilized per DLL imported, the number of functions that have additional (non-alphabetic) characters, the number of 'blacklisted functions' utilized by that PE file, the number of 'whitelisted' functions, whether all Register keys opened/ created are deleted at the end of the application, the number of native functions utilized, and how many times a function is accessed from Python.

Ransomware_Detection_Using_Features_of_PE_Imports_2
A dataset of Portable Executable files and the features extracted from their imports (PE Imports). The following are the features extracted: 1. The number of functions utilized per DLL imported as a ratio, 2. The number of 'bogus' functions, that is functions that are made-up and typically have additional (non-alphabetic) characters in the name, 3. The number of functions utilized by that PE file that are blacklisted as functions typically imported by ransomware files, 4. The number of functions utilized by that PE file that are typically imported and used exclusively by good-ware files 'whitelisted' functions, 5. The difference of the number of register keys opened/ created and those deleted by the end of the application, and 6. The number of native functions utilized by the PE file.
