Computer hackers have repeatedly made their way into the Nasdaq Stock Market’s computer network within the past 12 months, the media reported Saturday.
In a written statement, published by the Wall Street Journal, the Nasdaq company said during its normal security screening, it discovered “malware” files installed on a part of its network called Directors Desk, a service designed to allow company boards to communicate by securely storing and sharing documents.
The Wall Street Journal reported that part of the system that executes trades was not breached, sources told the newspaper.
However, other parts of Nasdaq’s infrastructure were accessed. Investigators from the Secret Service and Federal Bureau of Investigation are looking into the matter.
Investigators, speaking under anonymity, told the newspaper “so far the perpetrators have just been looking around.”
So far investigators have been unable to follow the trail back to any specific individual or country, and are unsure of whether they have plugged all of the network’s potential security gaps.
