Following the October 2015 cyberattack, we have been conducting a forensic review to ensure that all aspects of our security are as robust as possible – including that of our suppliers. 
As part of the review, we have been working with Wipro, (a call centre provider to TalkTalk and a number of other major businesses) and the local Police in Kolkata.  Acting on information supplied by TalkTalk, the local Police have arrested three individuals who have breached our policies and the terms of our contract with Wipro. We are also reviewing our relationship with Wipro.
We are determined to identify and deal effectively with these issues and we will continue to devote significant resource to keeping our customers’ data safe.  Data theft and scams are a growing issue affecting all businesses and they are notoriously difficult to investigate and prosecute.  We are pleased that our investigations have yielded results, and will continue to do everything we can to tackle these crimes.
