TORONTO — There are changes coming to Ashley Madison, the dating service for people looking for partners outside their marriage.

The Toronto-based company that owns Ashley Madison says it has a new chief executive and a new president and new measures in place against privacy breaches.

A high-profile cyberattack last year exposed data on millions of people purported to be clients of the adultery service.

Company founder and former CEO Noel Biderman left last August in the wake of the hacking attack — which raised questions about whether the company would be able to survive.
