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. In response to the breach, Tata Electronics has hired consultants for a forensic audit and notified the Indian government, while Apple is working closely with the vendor on remedial measures.

Security Controls Tightened Following Incident

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 stated that its business operations remain unaffected. However, the breach has led to tightened security controls and restricted employee access to internal systems. A source familiar with the matter indicated that Apple is investigating the incident and that Tata received a ransom demand following the attack.

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.
