Noel Biderman is stepping down as CEO of Avid Life Media, the parent company of adultery website Ashley Madison, the victim of a high-profile hack that exposed the personal information of millions of users.

“This change is in the best interest of the company and allows us to continue to provide support to our members and dedicated employees,” Avid Life Media said in a statement. “We are steadfast in our commitment to our customer base.”

Avid Life Media will be led by the “existing senior management team” until a new CEO is chosen, the company said.

A hacker or group of hackers known as the Impact Team claimed responsibility for the security breach last week. They exposed the email addresses, names, and more of millions of users of the site, which claims to connect people who are looking to have affairs. The company is currently facing at least five lawsuits seeking class-action status and more than a half-billion dollars.
