The Mumbai-based business stated that the attack had an effect on some of its IT systems in a succinct statement that was made public on Friday.

'In order to recover and restore the systems, the company took action. All essential operational systems are running, but as an extra precaution, restricted access and preventive measures have been implemented for portals and touchpoints that are used by employees and customers, the company stated in its filing (PDF) with local stock exchanges. Tata Power withheld any further information on the circumstance. When questioned by TechCrunch, a PR person declined to provide information about the nature of the attack, its effects on the company, and whether any data was stolen.

The company generates, transmits, and sells electricity in the country of South Asia. It aims to increase the proportion of clean energy in its portfolio from about a third to 60% in five years and to achieve net zero by 2045. 

Recently, they have become interested in the business growth of Tata Power through rooftop solar, microgrids, storage choices, solar pumps, EV charging infrastructure, and home automation. 

In its public pronouncements, the Indian government has cited the nationwide energy network's cybersecurity as a challenge. Chinese state-sponsored hackers allegedly targeted the Indian electricity sector as part of a long-term scheme, according to a report released in April by the American cybersecurity firm Recorded Future. In response to that news, the spokesperson for India's Ministry of External Affairs, Arindam Bagchi, stated that the nation has not brought up this matter with China. Zhao Lijian, a spokesperson for China's foreign ministry, reportedly denied the charge.
