What is Ashley Madison on Wikipedia?

Ashley Madison is an online dating service and social networking service marketed primarily to people who are already in a relationship. Wikipedia notes that it was founded in 2002 by Darren J. Morgenstern, with the slogan "Life is short. Have an affair." The site gained significant notoriety in July 2015, when a group named The Impact Team stole its user data and threatened to release users' names and personally identifying information if Ashley Madison was not immediately shut down. Following a failure to comply with the demand, the hackers released the data of millions of users, leading to considerable personal and professional repercussions for those individuals involved. Ashley Madison's business model is based on credits rather than monthly subscriptions, where members use credits to chat with other members. Since the cyber attack, Ashley Madison has rebranded itself, attempting to move away from its "infidelity" roots and focusing on being a platform for all kinds of relationships.
