Warrington, UK, Nov 6, 2015 -- Phone, internet and TV provider TalkTalk has issued an update on the impact of the cyber attack on its systems two weeks ago.
The group said it has been working to establish exactly what happened and understand the extent of any individual customer data stolen during this attack.
The statement said: "Investigations by both TalkTalk and the Metropolitan Police continue, and further to our update on October 30, we are now able to confirm which customers were affected: The total number of customers whose personal details were accessed is 156,959; of these customers, 15,656 bank account numbers and sort codes were accessed; the 28,000 obscured credit and debit card numbers that were accessed cannot be used for financial transactions, and were ‘orphaned’, meaning that customers cannot be identified by the stolen data.
"Our ongoing forensic analysis of the site confirms that the scale of the attack was much more limited than initially suspected, and we can confirm that only 4% of TalkTalk customers have any sensitive personal data at risk.
"However, we continue to advise customers to be vigilant, and to take all precautions possible to protect themselves from scam phone calls and emails."
The group said it was a difficult decision to notify all its customers of the risk before it could establish the real extent of any data loss: "We believe we had a responsibility to warn customers ahead of having the clarity we are finally able to give today.
"We have now contacted all customers who have had financial details accessed, reiterating our advice on what to do to keep themselves safe."
And it added: "The financial information accessed cannot, on its own, lead to financial loss. We will be contacting all other affected customers in the coming days.
"We want to make customers aware that we will not call or otherwise contact them regarding this incident and ask for bank details or other financial or personal information."
