AntiPublic

In December 2016 a massive collection known as AntiPublic was released into the public domain. This breach contained 458 million unique email addresses and plaintext passwords. The dataset served as a major resource for credential stuffing attacks where hackers exploited the common practice of password reuse across multiple platforms. Unlike typical targeted breaches this was a compilation of existing leaks aggregated into a single searchable database helping attackers identify active credentials across various services globally.
