TalkTalk suffered a series of security issues in 2015. Right from the start of the year people were discussing an increased number of scam calls. On 26 February 2015 TalkTalk emailed customers to inform them of a data breach in which account numbers, addresses, and phone numbers were taken. The email detailed that a third-party contractor was believed to be responsible, and that TalkTalk was taking legal action against them. It was believed that “a few thousand” customers were affected.

On 10 August 2017, TalkTalk were fined again for failing to adequately protect personal data “because it allowed staff to have access to large quantities of customer’s data” which “left the data open to exploitation by rogue employees”.
