NEW YORK — The computer network that runs the Nasdaq Stock Market in New York has been penetrated by hackers multiple times during the past year, according to a report by the Wall Street Journal on Friday.
Federal investigators were trying to identify the perpetrators and their motive.
According to the report, people familiar with the investigation said the exchange's trading platform, the system which executes trades, was not compromised.
A person involved in the Nasdaq investigation told the newspaper that so far the perpetrators "appear to have just been looking around."
The paper said possible motives include financial gain, theft of trade secrets or a national security threat designed to damage the exchange.
The US Secret Service initiated the probe, and the FBI is also investigating.
