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," Tea said in a statement to CBS MoneyWatch.

Tea, a women's dating safety app that 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.

Two class-action lawsuits were filed on Monday against Tea, the app where women can leave anonymous dating advice.
