Marcie Geffner: Can hackers tap your bank account?

By Marcie Geffner - Bankrate.com

If you use a credit or debit card, bank online or make any kind of electronic financial transaction, you face some risk that your personal information or money could be stolen.

That means pretty much everyone is exposed to this threat. And data breaches, where many of these financial misdeeds begin, have become common.

In November 2015, the U.S. Justice Department and other law enforcement agencies accused several men of a massive criminal computer hacking scheme that included the largest known theft of customer data from a U.S. financial institution.

That attack targeted account holders at JPMorgan Chase, according to a company filing with the Securities and Exchange Commission. User contact information for 76 million households and 7 million small businesses was stolen during the breach.
