Donât rush to give clean chit to China. Mumbai power grid failure is a strong warning Future wars will be fought on cyber domain. Delay in response will allow Chinese cyber soldiers to infiltrate Indian systems so deeply that de-coupling would become impossible. Seshadri Chari 5 March, 2021 11:32 am IST Text Size: A+ Union Minister Raj Kumar Singh has denied media reports that said the massive power outage in Mumbai last year was caused by a cyberattack from China, calling it a âhuman errorâ. Singhâs remark contradicts Maharashtra Home Minister Anil Deshmukhâs admission of a possible âcyber-sabotageâ, based on a preliminary report by the stateâs Cyber Cell. While both global and local press are alluding to the Mumbai power outage of 12 October 2020 to a China-based hacking system, it is intriguing that the Union minister should be in such a rush to give a clean chit to China.
