Rainbow Gmail Combolist

The Rainbow Gmail Combolist is a collection of credentials specifically targeting Gmail accounts. This dataset was released on a popular underground hacker forum in August 2022. It contains approximately 283 thousand lines of email addresses paired with passwords. The data is categorized as a combolist because it was compiled from various previous data breaches and credential stuffing operations rather than a single direct server compromise of Google services. Such collections are frequently used by cybercriminals to perform automated account takeover attacks across multiple platforms where users might reuse the same password.
