“Security experts say the recent “denial of service” cyberattacks on big U.S. banks were the largest ever recorded by a wide margin. Since Sept. 19, the banking websites of Bank of America Corp. (NYSE: BAC), J.P. Morgan Chase & Co. (NYSE: JPM), Wells Fargo & Co. (NYSE: WFC), U.S. Bancorp. (NYSE: USB) and PNC Financial Services Group Inc. (NYSE: PNC) have all suffered day-long slowdowns and been at times unreachable for many customers.
