Apple is investigating the leak of confidential documents and prototype images of its unreleased iPhone 18 Pro following a ransomware attack on Tata Electronics, one of the technology giant’s key manufacturing partners in India.
According to Reuters, the leaked data was published on the dark web by the ransomware group World Leaks, which had earlier claimed responsibility for stealing more than 200,000 files from Tata Electronics.
The documents reportedly contain sensitive supplier information, internal component records and photographs believed to show prototype iPhone 18 Pro devices undergoing durability testing.
The files also identify companies supplying key components, including chips, battery parts and camera modules, exposing details of Apple’s closely guarded supply chain.
A source familiar with the matter told Reuters that Apple considers the information highly sensitive because it relates to unreleased products.
The source added that the leaked documents map suppliers to specific iPhone components, information Apple does not disclose in its public supplier database.
Reuters said it was unable to independently verify the authenticity of the leaked files.
Neither Apple nor Tata Electronics responded to the news agency’s requests for comment, while World Leaks could not immediately be reached.
Among the leaked materials are documents bearing Apple’s confidential markings and internal code names linked to the iPhone 18 Pro generation. The cache also includes photographs dated early 2026 showing grey smartphones with Apple’s logo and a triple rear-camera setup.
Although Reuters could not independently confirm the devices’ identity, a source familiar with the documents identified them as iPhone 18 Pro prototypes.
The cyberattack comes as Apple accelerates efforts to expand manufacturing operations in India as part of its strategy to reduce dependence on China.
Tata Electronics has become one of Apple’s fastest-growing production partners, supplying components and assembling iPhones for the company.
In response to the breach, Tata Electronics has reportedly restricted access to sensitive internal systems and engaged a global consulting firm to conduct a forensic investigation.
Apple is also said to be working with the company on strengthening its cybersecurity measures.
Earlier reports indicated that the broader cache of stolen files also contained documents related to older iPhone models, Tesla components and records linked to Taiwan Semiconductor Manufacturing Company (TSMC) and Qualcomm, two major suppliers within Apple’s ecosystem.
The incident raises fresh concerns about cybersecurity within global technology supply chains and could strain the relationship between Apple and Tata Electronics as India assumes a larger role in the company’s worldwide manufacturing network.
According to Counterpoint Research, India is expected to account for 26 per cent of global iPhone production in 2026, up from six per cent four years ago.
