Prosecutors: Chinese targeted Pennsylvania firms

PITTSBURGH (AP) — Four major manufacturing firms that are based or do much of their work in western Pennsylvania, plus the United Steelworkers of America, were hacked by five Chinese army officials who allegedly stole trade secrets and other proprietary or sensitive information, federal authorities said Monday.

Westinghouse, U.S. Steel, Alcoa, and specialty steelmaker Allegheny Technologies Inc., or ATI, were targeted in the scheme that allegedly began in 2006, according to an indictment.
