A Russian hacker admitted Monday that he executed the largest known cyber-attack against a U.S. bank, pleading guilty to charges that he stole data on more than 80 million clients of JPMorgan Chase & Co. and other institutions that netted hundreds of millions of dollars in ill-gotten gains.
The hacker, Andrei Tyurin, 36, was accused of stealing customer information from 12 financial news companies, banks and other financial firms, including Fidelity Investments, E-Trade Financial and Dow Jones & Co. His co-conspirators used the information to ply customers with spam emails promoting stocks, hoping to cash out at higher prices, the government has said.
