experianExperian reported early October about a data breach involving T-Mobile customers.  In its Half-yearly financial report Experian issued a brief statement about this incident:

“North America security incident On 1 October we announced there had been an unauthorised access to a server in North America, containing files for one of our clients, T-Mobile USA, Inc. Our investigation to date reveals this was an isolated incident which affected a single client in our Decision Analytics business in North America and notably did not involve our US consumer credit bureau, nor did it include payment information or bank details. The consumers affected by this incident have been our first priority, and we have notified all of them and given them guidance on how they can protect themselves. We are also providing them with two years of free credit monitoring and identity protection services. We have been working relentlessly to resolve the issue and put additional measures in place to respond to this, including working with the US and international law enforcement agencies investigating this criminal incident. Data security has always been a key concern for us, and following this incident we will be reviewing measures to further improve and strengthen our security systems and processes.”
