JPMorgan, Four Other Banks Hit by Hackers: U.S. Official

Computer hackers targeted JPMorgan Chase & Co. and at least four other banks in a coordinated attack on major financial institutions this month, according to a U.S. official.

The attack led to the theft of customer data that could be used to drain accounts, according to another person briefed by U.S. law enforcement. The two people, who asked not to be identified because the investigation is continuing, discussed the incident after Bloomberg News reported a breach on banks earlier today.
