A data breach broker is selling the allegedly stolen user records for twenty-six companies on a hacker forum, BleepingComputer has learned.

When threat actors and hacking groups breach a company and steal their user databases, they commonly work with data breach brokers who market and sell the data for them. Brokers will then create posts on hacker forums and dark web marketplaces to market the stolen data.

Last Friday, a data broker began selling the combined total of 368.8 million stolen user records for twenty-six companies on a hacker forum.
