Russians Wage Insider Trading Hack Attack on Dow Jones

It is unclear if a newly-disclosed episode of alleged Russian espionage is related to a previous lower-grade hack into subscriber contact information that was announced a week ago. 

This time, the hacker group apparently stole information from Dow Jones servers to trade on the data before it became public.

The FBI, Secret Service and Securities and Exchange Commission began an investigation into the matter at least a year ago. 

The hackers might have retrieved information on stories being prepared for publication during their insider-trading escapade.
