New hack of women-only app Tea exposes personal chats, phone numbers

Just days after thousands of user images and locations were leaked in an apparent hack of archived app data, women-only safety app Tea is weathering data exposure at an even larger scale than first reported.

In addition to exposing thousands of user verification images and personal IDs, which were later abused by users on platforms like 4Chan, the app's recently discovered security flaws make it possible for hackers to access private messages between users. An independent security researcher, verified by 404Media, was able to pull conversations from a second database that were sent as recently as last week, which included sensitive information like shared phone numbers, conversations about intimate relationships, and discussions of abortion.

The researcher, Kasra Rahjerdi, also obtained access to back-end app features like the ability to send mass push notifications to users' devices. They told 404Media that the second vulnerability existed until late last week, around the time the initial hack was reported.

In a statement given on Friday, Tea said it was addressing the first database breach and that no current user data had been exposed. In a follow-up statement to 404Media, Tea wrote: "We are continuing to work expeditiously to contain the incident and have launched a full investigation with assistance from external cybersecurity firms. We have also reached out to law enforcement and are assisting in their investigation. Since our investigation is in its early stages, we do not have more information we can share at this time."

The Tea app recently shot up in popularity, following viral controversy over its existence as an alleged "man-shaming" app. Prior to the breach, some users were concerned with the app's storing of personal information (including that of both users themselves and the men they discuss), while others supported the need for women-only spaces online to share stories and protect each other's safety.

But while debate about the app's efficacy flared, online users took advantage of the app's vulnerable security system to target its female user base: Shortly after reporting on the first breach, hackers seized geolocation information stored in the legacy database to explicitly doxx users — who are promised anonymity upon making an account in order to more comfortably share warnings about encounters with men — and have since created a nationwide map with the locations of Tea users. Others pulled personal images from the database in order to ridicule their appearance in public forums, while a few created copycat apps designed for men to discuss intimate details of women's bodies.
