Late last week, Bloomberg reported Russian hackers had targeted the servers of media company Dow Jones in order to steal stock trading information.
People familiar with the matter told Bloomberg the Federal Bureau of Investigation, Secret Service and the Securities and Exchange Commission are investigating the attack, with the probe going back at least one year.
The sources also explained that the breach was far more serious than Dow Jones originally led on last week when it disclosed it was investigating hackers who attempted to access the contact and payment information of nearly 3,500 of its customers.
According to Bloomberg, it is unclear whether the two incidents are related.
Two of the people close to the investigation who spoke to Bloomberg said the hackers were also looking for news stories prior to publication, but it is unknown whether any news-gathering operations were impacted by the insider trading breach.
Shortly after Bloomberg’s report, Dow Jones quickly rebuffed the hacking reports.
In a statement, the company said, “To the best of our knowledge, we have received no information from the authorities about any such alleged matter.”
“We are looking into whether there is any truth whatsoever to this report by a competitor news organization,” Dow Jones said.
The FBI’s New York office confirmed with CNBC that it is aware of the breach at Dow Jones and is currently investigating.
