Computerworld via WSJ: “Federal authorities are investigating a computer intrusion at the company that runs the Nasdaq stock exchange, the Wall Street Journal reported Friday. According to the report, which cites anonymous sources, Nasdaq OMX Group computers were compromised sometime over the past year, but the company’s trading platform was unaffected. “So far, [the perpetrators] appear to have just been looking around,” the Journal quotes one source as saying. Nasdaq OMX Group runs a number of stock exchanges, including the U.S. Nasdaq, and exchanges that trade in Copenhagen, Stockholm, Helsinki, and the Baltic region. The investigation is being conducted by the U.S. Federal Bureau of Investigation and the U.S. Secret Service, the report states.”
