Tea, a provocative dating app designed to let women anonymously ask or warn each other about men they’d encountered, rocketed to the top spot on the U.S. Apple App Store this week. On Friday, the company behind the app confirmed it had been hacked: Thousands of images, including selfies, were leaked online.

Tea, a dating safety app which allows women to anonymously give men red or green "flags," says it had more than 70,000 photos stolen in a data breach.

The exposed data came from an old system that stored information over two years old and no recent data is affected.
