Hackers have breached the Tea app, which recently went viral as a place for women to safely talk about men, and tens of thousands of women’s selfies and photo IDs have now seemingly been leaked online.

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.

The images were being stored in a "legacy data system" containing information from more than two years ago, the company says.
