Reuters reports that Citigroup, a U.S.-based bank, announced that it had been hacked and customers’ private data was compromised:
Citigroup Inc said computer hackers breached the bank’s network and accessed the data of about 200,000 bank card holders in North America, the latest of a string of cyber attacks on high-profile companies.
Citi said the names of customers, account numbers and contact information, including email addresses, were viewed in the breach, which the Financial Times said was discovered by the bank in early May.
However, Citi said other information such as birth dates, social security numbers, card expiration dates and card security codes (CVV) were not compromised. […]
Another Citi spokesman, James Griffiths in Hong Kong, said the breach had affected 1 percent of North American card customers, which the bank’s annual report says total 21 million.
But like Japanese electronics and entertainment group Sony, which has declared several security breaches of its networks this year, Citi could come under fire for not telling customers sooner. […]
Citigroup joins a growing list of companies that have suffered cyber attacks.Â Data storage firm EMC Ltd this week offered to replace millions of electronic keys after hackers used data from its RSA security division to break into the network of arms supplier and information technology provider Lockheed Martin.
Sony has reported several attacks, including one in which hackers accessed the personal information on 77 million PlayStation Network and Qriocity accounts.
