The CEO of adultery website Ashley Madison is stepping down in the wake of the massive breach of the company's computer systems and outing of millions of its members.

Avid Life Media Inc., Ashley Madison's parent company, says Noel Biderman's departure was a mutual decision and in the best interest of the company.

Hackers originally breached Avid Life's systems in July and then posted the information online a month later after the company didn't comply with their demands to shut down.

Ashley Madison, whose slogan is "Life is short. Have an affair," purports to have nearly 40 million members.
