LeakBase Collection

The LeakBase Collection is a massive compilation of credentials sourced from the Mixed Database section of the Leakbase forum. In early 2023, a collection of files totaling 50 gigabytes was processed to extract unique email and password pairs. Originally containing around 1.5 billion rows, the dataset was refined through deduplication and removal of previously known collection data, resulting in a final set of 210 million unique records. This incident represents an aggregation of numerous historical breaches rather than a single new hack, providing a significant tool for credential stuffing attacks.
