TORONTO, Jan 18 (Reuters) - Schneider Electric SE disclosed on Thursday that hackers exploited a flaw in its software in a watershed hack discovered last month that halted plant operations at an industrial facility.
Schneider security officials told Reuters that they are working on a software update to fix the issue, but declined to say when it will be ready.
News of the incident surfaced on Dec. 14, when cyber security firms disclosed that hackers likely working for a nation-state had invaded one of Schneider's Triconex safety systems.
The company and security firms have declined to identify the victim or country where it occurred. (Reporting by Jim Finkle in Miami Beach, Florida Editing by Chizu Nomiyama)
