145 870 | Huge new Facebook data leak exposed intimate details of 3m users, May 15, 2018


Data from millions of Facebook users who used a popular personality app, including their answers to intimate questionnaires, was left exposed online for anyone to access, a New Scientist investigation has found.

Academics at the University of Cambridge distributed the data from the personality quiz app myPersonality to hundreds of researchers via a website with insufficient security provisions, which led to it being left vulnerable to access for four years. Gaining access illicitly was relatively easy.

The data was highly sensitive, revealing personal details of Facebook users, such as the results of psychological tests. It was meant to be stored and shared anonymously, however such poor precautions were taken that deanonymising would not be hard.

“This type of data is very powerful and there is real potential for misuse,” says Chris Sumner at the Online Privacy Foundation. The UK’s data watchdog, the Information Commissioner’s Office, has told New Scientist that it is investigating.
