Equifax has revealed 2.5 million more Americans than previously thought may have had information compromised in a huge cyber security breach at the firm.The credit report giant said on Monday about 145.5 million of its US customers might have been affected, up from a previous estimate of 143 million.The update came a day before former boss Rochard Smith testifies in Congress about the attack.Mr Smith apologised ahead of the hearing for the firm’s failings.Critics say the company failed to take proper steps to guard information – such as Social Security numbers, birth dates and addresses – and waited too long to inform the public.Equifax disclosed the attack last month, estimating that about 400,000 Britons and 100,000 Canadians may also have had data compromised.

DUBLIN (Reuters) – Ireland’s High Court on Tuesday said it would ask the EU’s top court to decide whether to ban the way in whoch Internet firms such as Facebook (FB.O) transfer users’ data to the United States in a case with major implications for companies.The case is the latest to question whether methods used by large tech firms such as Google (GOOGL.O) and Apple (AAPL.O) to transfer data outside the 28-nation European Union give EU consumers sufficient protection from U.S. surveillance.Data privacy is under the spotlight after revelations in 2013 by former U.S. intelligence contractor Edward Snowden of mass U.S. surveillance caused political outrage in Europe.
