Leak attributed to Tata Electronics gathers about 630 gigabytes and includes alleged manufacturing documents, internal records, and personal information.
A cybersecurity incident involving Tata Electronics has placed Apple and Tesla at the center of an investigation into the leak of confidential information.
The Indian company confirmed the attack on Monday, June 22, 2026, after researchers identified files allegedly linked to the two companies on the dark web.
According to Reuters, the group World Leaks released more than 200,000 files, which would total approximately 630 gigabytes of data.

The material would include industrial designs, manufacturing specifications, electronic messages, internal records, and copies of employees’ passports.
Reuters, however, highlighted that it could not immediately verify the authenticity of all the published content.
Tata Electronics identified attack weeks earlier
Tata Electronics stated that it detected the incident a few weeks before the public confirmation.
Internal response protocols were immediately activated to investigate and contain the problem.
The manufacturer assured that its operations were not affected and continued to function normally in all areas.
A source familiar with the case informed Reuters that Tata received a ransom payment demand related to the attack.
The Indian company refused to comment on the alleged charge.
Apple has begun a full analysis of the possible breach, according to another source heard by the agency.
Apple and Tesla did not respond to requests for comment sent by Reuters until the publication of the report.
Files related to Apple appear in the leak
Indian researcher Rajshekhar Rajaharia analyzed part of the documents made available by World Leaks.
The files attributed to Apple would include:
- Specifications of materials and production processes;
- Event records accumulated over several years;
- Electronic messages and internal documents;
- Copies of employees’ passports;
- Inspection standards for iPhone circuit boards.
A search for the term “Apple” would have returned 181 files and folders.
Part of the material was identified as “com.apple.factorydata” and referenced material specifications.
A 52-page document would detail quality inspection standards for components used in iPhone circuit boards.
Another 33 files and folders mentioned Hosur, the city that houses Tata’s main iPhone assembly unit in Tamil Nadu.
Tesla documents mention components and projects
Researchers also found files that would reference components used by Tesla.
A folder was named “NV36 Chargeport Controller – North America,” associated with an updated version of the Model Y SUV.
Another document, produced in 2023, would show drawings related to the Highland project, codename for the redesigned Model 3.
A search for the term “Tesla” also revealed possible manufacturing specifications and an assembly document dated May 2025.
Some files contained warnings indicating that the information was confidential, proprietary, and classified as Tesla trade secrets.
Data was available since June 10
Researcher Rakesh Krishnan stated that the documents had been accessible on the dark web since at least June 10, 2026.
Tata reportedly informed some employees in the iPhone assembly operations about the leak the week before the public confirmation.
World Leaks stated on its dark web page that it had stolen and published the data from the Indian manufacturer.
Reuters was unable to contact the group or independently confirm the origin of all the files.
Tata holds a strategic position in iPhone production
Tata Electronics currently accounts for about one-third of Apple’s iPhone production in India.
Foxconn represents the remainder of the company’s device manufacturing in the country.
The Indian company is establishing itself as one of Apple’s main industrial partners outside of China.
This expansion is part of Prime Minister Narendra Modi’s plan to transform India into a powerhouse in electronics manufacturing.
However, Apple’s supply chain in the country has already faced questions about possible contamination of agricultural lands near a component factory.
Tata Group has faced another cyberattack
The Tata Group also suffered, in 2025, an attack against the British automaker Jaguar Land Rover.
The invasion caused a production halt of approximately six weeks.
The new episode highlights the risks faced by large manufacturers and suppliers in the face of increasingly sophisticated digital attacks.
The Indian Computer Emergency Response Team did not immediately respond to requests for comment sent by Reuters.
