Millions of cheating spouses may soon be caught by their husbands and wives.

Hackers are threatening to release information about more than 37 million people who use Ashley Madison, a dating website for cheating spouses.

The hackers, known as The Impact Team, have warned that they will release the names, nude photos and sexual fantasies of Ashley Madison users unless the website is shut down.

Avid Life Media, which owns Ashley Madison, confirmed the security breach.

"We apologize for this unprovoked and criminal intrusion into our customers' information," Avid Life said.

Hackers also want Avid Life to shut down Established Men, the company's site for “sugar daddies.”

Reuters reported:

The breach comes about two months after dating site Adult FriendFinder was compromised. That site has an estimated 64 million members.

The Impact Team, in a screengrab showing on the Krebs blog, say it had taken over Avid Media systems including customer databases, source code, financial records and emails.

"Shutting down AM (Ashley Madison) and EM (Established Men) will cost you, but non-compliance will cost you more," the hackers said.

They said users who had paid a fee to Avid Life to have their personal data permanently deleted had been lied to and the company had retained records, including credit card information.
