The attack, Bloomberg said, led to the loss of sensitive data. It did not elaborate.
The New York Times, quoted sources as saying JP Morgan and at least four other firms were hit this month by co-ordinated attacks which siphoned off huge amounts of data, including customer account information.

The FBI said it was investigating the reports without confirming details.
