U.S. Steel Says Chinese Gov't Hackers Stole Plans

U.S. Steel Corp. is alleging that Chinese government hackers stole proprietary methods for making lightweight steel on behalf of Chinese steel producers seeking to supply a bigger share of the U.S. auto-making market. Pittsburgh-based U.S. Steel, in a complaint filed with the International Trade Commission, said a computer belonging to a Pittsburgh researcher was hacked in 2011, and that plans for developing new steel technology were stolen.
