The Federal Bureau of Investigation is probing a possible
computer hacking attack on J.P. Morgan Chase & Co., in what
people familiar with the probe described as a significant breach of
corporate computer security.
The extent of the hacking -- when it began, what it affected,
and what the potential costs for the company -- weren't immediately
clear.
The company and federal cyber investigators are in discussions
as they pursue the apparent attack on the bank's computers.
"Companies of our size unfortunately experience cyberattacks
nearly every day," said Trish Wexler, a J.P. Morgan spokeswoman, in
a statement. "We have multiple, layers of defense to counteract any
threats and constantly monitor fraud levels."
