NEW YORK (CNNMoney)

Banks have lost so much consumer information to hackers this year that two members of Congress are asking them to come clean with the extent of the damage.

Tuesday morning, 16 financial institutions will receive letters from Sen. Elizabeth Warren and Rep. Elijah E. Cummings asking them to admit that they have been hacked, explain how it happened and be transparent about what they lost.

In many cases, companies that are hacked never reveal it to their customers. Or they release vague, useless information that hides the seriousness of the breach.

Earlier this year, hackers broke into JPMorgan. The bank said hackers gathered information on more than 80 million customers. But sources close to the investigation told CNNMoney the hackers hit at least six other companies -- none of which came forward about it.
"The increasing number of cyberattacks and data breaches is unprecedented and poses a clear and present danger to our nation's economic security," Cummings and Warren wrote in the letter.
They noted that faith in banks' ability to keep consumer data safe "is central to earning and maintaining consumer confidence in our economic system." The letter referenced a recent USA Today report that hackers have stolen more than 500 million financial records over the past year.
Earlier this year, CNNMoney noted that half of American adults have been hacked.
