A Major U.S. Stock Exchange Did Something Right, Technologically


Sure, the Nasdaq got hacked by a bunch of sinister Russians, but this had less of an impact than some exchange's plans to extend hours.

Federal prosecutors unsealed criminal charges against a group of hackers who allegedly breached the computer systems of more than a dozen companies including Nasdaq OMX Group Inc., J.C. Penney Co. and Carrefour SA, to steal personal data and, in some cases, credit-card information, resulting in the loss of hundreds of millions of dollars….

While the hackers allegedly were able to penetrate Nasdaq's computer network and access the trading history of specific securities, the servers powering Nasdaq's exchanges weren't compromised, according to a person with knowledge of the exchange's systems. The identity of specific traders wasn't accessed by the hackers, the person said.

Nasdaq's so-called SQL servers, which run on a different operating system than those running the company's markets, maintain various public-facing websites listing share prices and providing forums for investor discussions, according to the person. The hackers purportedly got onto a Nasdaq network of about 30 such servers, gaining login information by tricking a site set up to remind site users of forgotten passwords.

Running Exchanges Is Too Hard, Exchange Chiefs Say

U.S. exchanges have become a handful to handle. It seems that all of the order types they've instituted over the years to keep customers and regulators happy may have had the opposite result. But it's not Elizabeth Warren or Bernie Sanders or some other Capitol Hill communist levying these charges. It's the exchanges themselves. And rather than doing something about the things they've done to make themselves "overly complex and opaque" at the expense of ordinary investors, they'd prefer to have Congress make them do something.
