A Second Tea Breach Reveals Users' DMs About Abortions and Cheating

A second, far more recent data breach at women's dating safety app Tea has exposed over a million sensitive user messages -- including discussions about abortions, infidelity, and shared contact info. This vulnerability not only compromised private conversations but also made it easy to unmask anonymous users. 404 Media reports: Despite Tea's initial statement that "the incident involved a legacy data storage system containing information from over two years ago," the second issue impacting a separate database is much more recent, affecting messages up until last week, according to the researcher's findings that 404 Media verified. The researcher said they also found the ability to send a push notification to all of Tea's users. It's hard to overstate how sensitive this data is and how it could put Tea's users at risk if it fell into the wrong hands. When signing up, Tea encourages users to choose an anonymous screenname, but it was trivial for 404 Media to find the real world identities of some users given the nature of their messages, which Tea has led them to believe were private. Users could be easily found via their social media handles, phone numbers, and real names that they shared in these chats. These conversations also frequently make damning accusations against people who are also named in the private messages and in some cases are easy to identify. It is unclear who else may have discovered the security issue and downloaded any data from the more recent database. Members of 4chan found the first exposed database last week and made tens of thousands of images of Tea users available for download. Tea told 404 Media it has contacted law enforcement. [...] This new data exposure is due to any Tea user being able to use their own API key to access a more recent database of user data, Rahjerdi said. The researcher says that this issue existed until late last week. That exposure included a mass of Tea users' private messages. In some cases, the women exchange phone numbers so they can continue the conversation off platform. The first breach was due to an exposed instance of app development platform Firebase, and impacted tens of thousands of selfie and driver license images. At the time, Tea said in a statement "there is no evidence to suggest that current or additional user data was affected." The second database includes a data field called "sent_at," with many of those messages being marked as recent as last week.
