Tata Electronics, a manufacturer of electronics and semiconductors based in India and a significant supplier for tech leaders like Apple and Tesla, acknowledged a data leak weeks after files allegedly sourced from the firm surfaced on a hacker platform.

This acknowledgment follows the hacker site listing that claims to provide over 630GB of data purportedly misappropriated from Tata Electronics, containing more than 204,300 files. An analysis of a selection of these files by TechCrunch revealed what seem to be specifications for Apple suppliers and documents related to Tesla manufacturing. The validity, origin, and completeness of this data could not be independently confirmed.

Established in 2020, Tata Electronics has become a vital entity in India’s initiative to boost manufacturing in electronics and semiconductors. The company runs various facilities throughout India and employs over 75,000 people, according to its parent company’s site. Tata has developed collaborations with international firms like Apple, ASML, Intel, Qualcomm, and Tesla as manufacturers seek to diversify supply chains beyond China and increasingly consider India as a viable production center.

Cybersecurity expert Rajshekhar Rajaharia informed TechCrunch that the data promoted on the forum included Outlook email conversations, information related to SAP, and documents allegedly associated with some of Tata Electronics’ clients, including Apple and Tesla.

A spokesperson for Tata Electronics confirmed the occurrence in a statement to TechCrunch, indicating that the company detected a cybersecurity event on some of its systems “a few weeks ago” and promptly initiated its response measures. The spokesperson remarked that the incident had “no impact on our operations across businesses, which remain unaffected.”

However, the company refrained from responding to inquiries regarding the specifics of the compromised data, the number of individuals or organizations impacted, whether customers had been informed, and if any client information belonging to entities like Apple and Tesla was made publicly available.

Reuters reported that Tata Electronics communicated with some employees involved in its iPhone assembly operations last week regarding the data breach. The report also indicated that Apple was looking into the matter and that a ransom had been demanded from Tata Electronics.

This breach occurs as Tata Group takes on a more prominent role in global tech supply chains. The company commenced iPhone manufacturing in 2023 by purchasing the Indian operations of Taiwanese contract manufacturer Wistron, a longtime supplier to Apple. Tata Electronics later gained a 60% interest in the Indian branch of Pegatron, another key partner for Apple manufacturing.

Tata also entered into a semiconductor supply agreement with Tesla in 2024, underscoring its growing ties with some of the largest tech companies in the world.

Apple and Tesla have not replied to TechCrunch’s requests for comments.
