Hackers have followed through on a threat to release online a huge cache of data, including customer information, that was stolen a month ago from cheating spouses website AshleyMadison.com, several tech websites reported on Tuesday. A group calling itself Impact Team had leaked snippets of the compromised data in July and threatened to publish names and salacious details about clients unless Ashley Madison and EstablishedMen.com, another site owned by Toronto-based parent company Avid Life Media, were taken down.
