Hackers breach Nasdaq's computers

[Swede]

"It's scary to think that a major electronic exchange could be hacked," said Jack Ablin, chief investment officer at Harris Private Bank in Chicago.

"The flash crash undermined investor confidence last year. It appears that the SEC is powerless to act," he said. "The watchdog is a paper tiger."

The revelation comes a week after an hour-long computer glitch locked the prices of two key Nasdaq indexes, though exchange spokesman Frank DeMaria said hackers played no role in that incident.
