TalkTalk hack: 4% of customers' data accessed in cyber security breach

Amanda Parker writes: TalkTalk has announced that 156,959 customers had their personal details accessed as a result of the recent attack on its website, of which 15,656 bank account numbers and sort codes were stolen. In an update, the firm also said the 28,000 credit and debit card numbers that were accessed were obscured, i.e. had part of the number asterixed out, and so are unusable for financial transactions. They were also "orphaned", says TalkTalk, so customers are unable to be verified by the stolen data.
