The 2017 Dixons Carphone data breach was originally found to have compromised 1.2 million customers’ details including personal information, names, addresses and email addresses, but it’s now been found to have affected 10 million customers.
This revelation comes just weeks after the company announced that attempts had been made to obtain details of 5.9 million payment cards.
No bank account details were accessed and there is no evidence of fraud.
Dixons Carphone, which is still investigating the cyber breach discovered in June this year, has closed off unauthorised access and implemented new security measures.
A statement from the company’s chief executive, Alex Baldock, admitted to falling short and that the company was fully committed to put it right and make customers’ personal data safe.
He also confirmed that Dixons Carphone would contact its “customers to apologise and advise on the steps they can take to protect themselves.”
