Russian hackers breached Dow Jones for trading tips

After a year-long investigation, Bloomberg has reported details on the extent of a data breach, and the motive behind it.

Russian hackers had infiltrated Dow Jones & Co to steal information to trade on before it was made public, and the breach was “far more serious than a lower-grade intrusion” disclosed by the company, Bloomberg reported, citing sources.

The Federal Bureau of Investigation, Secret Service and the Securities and Exchange Commission are leading an investigation, which began at least a year ago, Bloomberg reported. (http://bloom.bg/1LSxcUI)
