This repository contains a large dataset for the research of domain generation algorithms (DGAs) and machine learning. At the time of writing the dataset contains more than 90m of domains and more than 100 families.

The dataset consists of SLDs from DGAs and their extracted features. The main sources for the DGAs are the following:

When the samples were sparse, we used the reversed code to create new ones.

Moreover, it has SLDs from three adversarial DGAs (referred to deception, deception2 and khaos) DGAs and SLDs from the top 1m Alexa domains.
