In recent months, cyber criminals have targeted numerous financial institutions and they’ve jeopardized millions of customers, most notably, at JP Morgan Chase. CCTV America’s Karina Huber reports.

This summer’s cyber attack on JP Morgan Chase affected 76 million households and 7 million small businesses. The attacks came less than a year after hackers stole data on customers at U.S. retailers like Target and Home Depot.

The JP MOrgan Chase hackers also tried to gain access to data on customers at Citigroup, HSBC, online broker E*Trade, and payroll processing firm ADP among others. The source of the attacks is unknown.

Chase said no money has been stolen but hackers got the names, phone numbers, home and email addresses of their customers, which makes Chase clients particularly vulnerable to phishing, such as spammers who pose as legitimate organizations and send emails asking for more information or money. Banks said they will cover losses caused by hackers, but experts said the best line of defense lies in the hands of consumers.

The data breaches have triggered numerous investigations by the FBI and U.S. federal prosecutors. Experts said if there is one silver lining, it is that banks are going to be more vigilant.
