More than 90 servers of JP Morgan were attacked by hackers for over two months starting from June, but sources from the company privy to the investigation into the incident said hackers could not lay their hands on the money.
The New York Times reported that JP Morgan recently briefed the US financial regulators on the extent of damage.
The bank’s investigation found out that hackers were able to find individual computers within the bank, got administrative privileges and were able to review information of more than a million accounts.
However, JP Morgan claims that hackers could not gain access to the account holders’ financial information or social security numbers.
Sources within JP Morgan mentioned that it was difficult to find every vulnerability but it has patched all the known ones, and secured the systems against future attacks.
According to the investigators, the attack was well planned, and might have involvement of foreign government.
JPMorgan spokeswoman Kristin Lemkau said: "We uncovered an attack by an outside adversary recently where the firm’s technology environment was compromised."
"We are confident we have closed any known access points and prevented any future access in the same way."
"There was no evidence that they have taken any proprietary software or had a blueprint of the bank’s computer network."
