Britain's TalkTalk cyber attack to cost company up to €50m

Britain’s TalkTalk put the cost of last month’s cyber attack at £30m-£35m (€42m-€49m), and said it was too soon to gauge the impact on customer numbers, although it did see an immediate spike in defections.

Chief executive Dido Harding said it had been a “challenging time” for the broadband company’s four million customers.

“We obviously saw an immediate bounce in customers wishing to cancel their direct debits and to churn, but we saw those leading indicators come back down quite quickly,” she said, before adding, “The early signs are encouraging that we are doing the right thing.”
