How did the ‘data breach’ actually happen?

The data scientist from Cambridge University, Aleksandr Kogan provided his own app ‘this is your digital life’ to Cambridge Analytica which in turn arranged a briefed consent process for research wherein several hundred thousand users of Facebook would give the nod on an academic basis to finish a survey. It is, of course, the Facebook design that allowed the app not only to collect the personal data of people who agreed to take the survey but even includes the personal information of all the people in that user’s social network in Facebook. In this manner, Cambridge Analytica extracted data from millions of Facebook users since 2014.         ( What did the CA’s scandalous data breach cost Facebook? : source - The Quint ) Despite this, the controversial data firm issued a false statement which says that the data obtained from the data scientist Kogan has not been used to influencing people’s pulse in the 2016 presidential campaigns of Donald Trump, and Ted Cruz.
