The incident has raised fresh concerns about cybersecurity across the global technology supply chain, particularly as major technology companies increasingly rely on third-party manufacturing partners.

It remains unclear whether the targeted facility was Tata's plant in Hosur, Tamil Nadu, which has recently faced separate controversy over allegations of local water pollution.

However, early reports indicate that the stolen data includes at least 33 files and folders directly associated with the Hosur facility.

A spokesperson for Tata Electronics confirmed that the company detected a cybersecurity incident affecting several internal systems several weeks ago.

According to the company, emergency response procedures were activated immediately and manufacturing and business operations have continued without disruption.

Hacker group claims to have published more than 200,000 files

The cybercriminal group known as World Leaks claims to have publicly released more than 200,000 files obtained from Tata's factory. The total volume of the leaked data reportedly exceeds 630GB.

Although the authenticity of the full dataset has not been independently verified, several files reportedly carry notable names such as "com.apple.factorydata" alongside Apple engineering documents relating to manufacturing material specifications.

Among the leaked materials is also said to be a 52-page technical document outlining quality inspection standards for iPhone circuit boards.

A cybersecurity expert who reviewed data circulating on underground forums said the Apple-related archive also appears to contain employee passport copies and several years of internal system logs.

If confirmed, the breach would represent a significant data leak involving not only technical information but also employees' personal data.

Tesla may also have been affected

Apple is not believed to be the only company impacted.

Tesla also reportedly appears in the leaked dataset. Although final verification has not yet been completed, the published files are said to include engineering drawings for Project Highland, the updated Model 3 introduced by Tesla in 2023.

The leaked materials are also reported to contain manufacturing assembly documents dated May 2025 and numerous references to components used in the Model Y SUV.

If authentic, the documents could expose sensitive information relating to the American electric vehicle maker's manufacturing and product development activities.

Another cybersecurity researcher said data relating to both Apple and Tesla first appeared on cybercriminal file-sharing channels on June 10, 2026.

World Leaks is well known within the cybersecurity community for conducting data extortion campaigns. One of its most high-profile previous attacks targeted Nike in January 2026.

Tata Electronics has declined to confirm whether the latest incident involved ransomware.

However, publicly releasing stolen data to pressure victims has become a common tactic among modern cybercriminal groups.

Apple has not issued an official statement. However, a source familiar with the matter reportedly said the company is conducting a comprehensive assessment to determine the scale of the incident and verify the authenticity of the leaked documents.
