A cyberattack on Tata Electronics has reportedly exposed thousands of sensitive files linked to Apple Inc. and Tesla Inc., prompting investigations into the scope of the breach and the security of critical supply-chain data. The incident, identified several weeks ago, has escalated with a ransomware group claiming to have published over 200,000 files on the dark web, totaling more than 630 gigabytes. Despite the breach, Tata Electronics stated that its business operations remain unaffected, though the exposure of alleged trade secrets raises significant concerns for its high-profile partners.

Apple Supplier Says Operations Remain Unaffected

On Monday, Tata Electronics confirmed that it had identified a cybersecurity incident affecting some of its systems and immediately activated its response procedures. The company asserted that the breach has had no impact on business operations. However, a source familiar with the matter indicated that Apple is investigating the incident and that Tata received a ransom demand following the attack. This development poses a new challenge for Apple's expanding manufacturing network in India, where Tata has become a key partner outside of China.

Hackers Claim To Have Published 200,000 Files

Cybersecurity researchers reviewing the leaked material attributed the data dump to the ransomware group World Leaks. The group's website allegedly contains folders referencing Apple manufacturing data, material specifications, and factory-related documents. Additionally, the archive reportedly includes employee emails, system logs, and copies of employee passports. Researchers noted that the files had been available on the dark web since at least June 10.

Tesla Engineering Data Also Reportedly Exposed

The data dump reportedly contains documents linked to Tesla, including engineering drawings, manufacturing specifications, and files associated with Project Highland, Tesla's internal codename for the refreshed Model 3. Some documents reportedly carried labels describing the information as "trade secret" or "confidential." The material reviewed also included files tied to Tesla components and Apple quality-control procedures for iPhone parts.

Supply Chain Security Under Spotlight

The incident underscores the growing cybersecurity risks facing global manufacturers and technology supply chains. Tata currently accounts for roughly one-third of iPhone production in India, with Foxconn Technology Group producing the remainder. As Apple seeks to diversify its manufacturing base beyond China, the security of its suppliers' data infrastructure remains a critical focal point.
