Situation — AI, digital and software projects

Our app launches soon, and we have never tested its security.

Context

Launch day is getting closer. The team has put all its energy into features. Security can wait.

But a successful launch draws a crowd. Users, and hackers too.

The problem

  • A flaw found after launch gets fixed in front of your users, not behind closed doors.
  • Photos, ID documents, messages: what your users entrust to you is what hackers are after.
  • What you promise about your data must be true in the code, not just in your terms of use.

Case study

Real-life caseJuly 2025

Tea, dating review app for women, United States

In July 2025, in the United States, the Tea app saw a surge of interest: more than two million new access requests. It lets women share reviews of their dates.

Hackers then gained unauthorised access to its systems. They took 72,000 images, including around 13,000 selfies and ID photos submitted for account verification.

Yet the company claimed it deleted these selfies after verification. The affected accounts had been created before February 2024: the flaw involved old data, and it surfaced just as the app took off.
