Citigroup fixing iPhone banking security flaw

SAN FRANCISCO: Banking colossus Citigroup on Monday released an update to stop its iPhone mobile banking software from secretly squirreling away basic account and transaction data.

"During a recent review, we discovered that our US Citi Mobile iPhone banking app was accidentally saving information related to customer accounts in a hidden file on their iPhones," Citigroup said in a release.

"This information may also have been saved on their computer if they had been synchronizing their iPhone with their computer via iTunes," it said.

Citigroup was urging iPhone mobile banking customers to install the software update, which deletes any data that might have been saved unintentionally and fixes the problem.

"We have no reason to believe that our customers' personal information has been accessed or used inappropriately by anyone," Citigroup said. "There has been no data breach."
