Tea's investigation of the incident found that app users' direct messages had been breached, along with some of their photos. "Out of an abundance of caution, we have taken the affected system offline," San Francisco-based Tea said in a statement to CBS MoneyWatch.

Its full name is Tea Dating Advice, and the central idea is a women-only app that gives those who are dating the ability to access background checks on men. This includes whether they have a criminal record (or if they're sex offenders), as well as reverse image searching to identify catfishing (assuming a false identity online).

Tea, a women's dating safety app that recently surged to the top of the free iOS App Store listings, suffered a major security breach last week. The company confirmed Friday that it "identified authorized access to one of our systems" that exposed thousands of user images. And now we know that DMs were accessed during the breach, too.
