Millions of bank customers were unable to access their bank accounts and bank online as reported by the New York Times. The bank customers “of Bank of America, JPMorgan Chase, Citigroup, U.S. Bank, Wells Fargo and PNC, …could not get access to their accounts or pay bills online.” The report went on to say:
The banks suffered denial of service attacks, in which hackers barrage a Web site with traffic until it is overwhelmed and shuts down. Such attacks, while a nuisance, are not technically sophisticated and do not affect a company’s computer network — or, in this case, funds or customer bank accounts. But they are enough to upset customers.
Although experts believed these attacks were not sophisticated, rather by a “number of so-called hacktivists,” these acts show how easy it is to have successful cyber attack. So the US government should do more to protect US businesses.
