(Via MSN) Hackers threatened to leak details including the credit card information, nude photos and sexual fantasies of as many as 37 million customers of a dating website that caters to cheating spouses, the KrebsOnSecurity blog reported.

The dating website AshleyMadison.com’s Canadian parent, Avid Life Media, confirmed the breach on its systems, and said it had since secured the site and was working with law enforcement agencies to trace those behind the attack.

It disputed a claim made by the hackers, who call themselves The Impact Team, that a “paid delete” function will not remove all information about a member’s profile and communications. Following the breach, Avid Life said in a statement it would offer the function free of charge.

Company officials could not immediately be reached for comment. But in an interview with KrebsOnSecurity, Avid Life Chief Executive Noel Biderman was cited as saying the company suspected someone who had had access to internal networks as being behind the breach.

“It was definitely a person here that was not an employee but certainly had touched our technical services,” he said.
