Tata Electronics Confirms Data Breach — Over 630GB of Files Involving Apple and Tesla Leaked on Hacker Forum

Tata Electronics, the Indian electronics and semiconductor manufacturer that serves as a core supplier to Apple, Tesla, and other global tech giants, has confirmed it suffered a data breach after a cache of files allegedly stolen from the company surfaced on a hacker forum. The breach, detected weeks ago and only now publicly acknowledged, raises serious questions about supply chain security for some of the world’s most valuable technology companies.

The hacker forum listing claims the operators possess more than 630GB of data purportedly exfiltrated from Tata Electronics’ systems, encompassing over 204,300 files. TechCrunch, which reviewed a sample of the leaked files, reported that the material appears to contain Apple supplier technical specification documents as well as Tesla production and manufacturing data. No independent third party has yet been able to verify the authenticity, origin, or completeness of the entire dataset.

Founded in 2020, Tata Electronics has rapidly become a linchpin in India’s ambition to establish itself as a global electronics manufacturing hub. With over 75,000 employees and multiple production sites across India, the company has secured strategic partnerships with Apple, ASML, Intel, Qualcomm, and Tesla. Its rise parallels the broader industry push to diversify supply chains beyond China, positioning India as a critical alternative manufacturing center.

Cybersecurity researcher Rajeshkhar Rajaharia disclosed that the data being sold on the forum includes Outlook email correspondence, SAP system records, and documentation apparently tied to Tata Electronics’ clients — with both Apple and Tesla named among them.

A Tata Electronics spokesperson confirmed the incident in a statement to TechCrunch, saying the company detected a cybersecurity vulnerability in some of its systems “several weeks ago” and immediately activated its emergency response protocols. The spokesperson added that the breach “has not impacted the operations of any business lines, and all operations continue to function normally.”

However, the company declined to respond to questions about the specific types of data compromised, how many individuals and organizations were affected, whether its client partners — including Apple and Tesla — have been notified, or whether any of their data was actually exposed.

Reuters reported that Tata Electronics informed some employees in its iPhone assembly business about the breach last week. The report also noted that Apple is investigating the incident, and that the hackers have demanded a ransom payment from Tata Electronics.

The breach unfolds at a pivotal moment for the Tata Group’s role in the global technology supply chain. In 2023, Tata acquired the India operations of Wistron, Apple’s long-standing contract manufacturer, formally entering the iPhone assembly business. It subsequently acquired a 60 percent stake in the Indian subsidiary of Pegatron, another key Apple assembler. In 2024, Tata signed a semiconductor supply agreement with Tesla, further cementing its expanding relationships with the world’s leading technology companies.
