The warning, from the Financial Services Information Sharing and Analysis Center, cited "recent credible intelligence regarding the potential" for cyber attacks as the reason for raising the threat level to "high" from "elevated."
Earlier on Wednesday the consumer banking website of JPMorgan Chase & Co was intermittently unavailable to some customers. The problems followed issues with the website of Bank ofAmerica Corp on Tuesday amid threats on the Internet that a group was planning to launch cyber attacks on a U.S. bank.
JPMorgan Chase spokesman Patrick Linehan said, "We're experiencing intermittent issues with Chase.com. We apologize for any inconvenience and are working to restore full connectivity.
A Bank of America spokesman reported no continuing problems on Wednesday. "Our online banking services have been, and are, up and running," Mark Pipitone said. "The vast majority of our customers have not experienced any issues."
The short advisory from the industry group urged banks and other industry members to "ensure constant diligence in monitoring and quick response to any malicious events."
