Ukraine’s national bank, state power company, largest airport, Russia’s biggest oil company, shipping firm A.P. Moller-Maersk and British advertising agency WPP have become victims this time.
BBC News reported that the Windows-based radiation sensors at Chernobyl nuclear power plant were shut down and workers had to manually monitor radiation levels.
