What is the scandal involving Noel Biderman and Ashley Madison?

The scandal involving Noel Biderman and Ashley Madison erupted in July 2015, when a group calling themselves "The Impact Team" hacked into Ashley Madison's systems and stole user data from the infidelity website. Noel Biderman, who was the CEO of Avid Life Media, the parent company of Ashley Madison, faced immense scrutiny as private information of millions of users was threatened to be released unless the site shut down. Despite efforts to secure user data and keep the site operational, in August 2015, the hackers released a trove of data including members' personal details and sensitive information. This high-profile breach not only jeopardized the privacy and relationships of users across the globe but also highlighted issues of cybersecurity and ethical business practices, eventually leading to Biderman's resignation from his position as CEO by the end of August 2015. The scandal ignited a debate on internet privacy, cybersecurity, and morality in digital business.
