Experian (2015)

In September 2015, the US based credit bureau and consumer data broker Experian suffered a data breach that impacted 15 million customers who had applied for financing from T-Mobile. An alleged data breach was subsequently circulated containing personal information including names, physical and email addresses, birth dates and various other personal attributes.
