Hackers claim to have personal details of more than 37 million cheating spouses on dating website Ashley Madison and have threatened to release nude photos and sexual fantasies of the site’s clients unless it is shut down, blog KrebsOnSecurity reported.
Ashley Madison’s Canadian parent Avid Life Media confirmed the breach on its systems and said it had since secured its site and was working with law enforcement agencies to try to trace those behind the attack.
Avid Life did not disclose what information was stolen.
The hackers, who call themselves The Impact Team, leaked snippets of the compromised data online and warned they would release customers' real names, profiles, nude photos, credit card details and "secret sexual fantasies" unless their demands were met, Krebs said.
They also demanded the closure of another Avid Life Media's sites - sugar-daddy site Established Men - but did not target the company's CougarLife site, which caters for women members looking for "a young stud".
Ashley Madison, which uses the slogan, "Life is short. Have an affair", has been planning to raise up to $200 million through an initial public offering on the London Stock Exchange.
"We apologise for this unprovoked and criminal intrusion into our customers' information," Avid Life said, adding the hackers left behind posts and images on the website detailing their demands.
