BEIJING, July 27 (Xinhuanet) -- Banking colossus Citigroup urged customers to upgrade its iPhone banking software after discovering a potential security flaw in the app, according to The Wall Street Journal reports Tuesday.
In a statement, Citigroup said the original app accidentally saved information from a banking customer’s account into a hidden file on the iPhone.
"We have no reason to believe that our customers' personal information has been accessed or used inappropriately by anyone," said spokeswoman Natalie Riper in a statement. "There has been no data breach."
The Citi Mobile iPhone banking program let U.S. Citibank customers see their account and credit card balances, pay bills and transfer money, and helped them locate nearby ATMs.
The issue affected the approximately 117,600 customers who had registered the iPhone app with Citi since its launch in March 2009, a person familiar with the matter said. Other Citi mobile apps such as the app for credit-card customers are not affected.
