Tata Electronics Tightens Security After Alleged Dark Web Data Leak

Tata Electronics has tightened internal access to sensitive systems after an alleged leak of confidential client files surfaced on the dark web, prompting a forensic investigation and heightened scrutiny of one of Apple’s most important suppliers in India. The company has also informed the Indian government and affected clients while working to determine the scope of the cybersecurity incident.

Tata Restricts Access to Sensitive Systems

Tata Electronics has restricted employee access to critical internal systems following the suspected data breach, according to a company source and industry officials familiar with the matter.

The company has also appointed a global consultant to carry out a forensic audit as investigators examine how thousands of confidential files were allegedly exposed. The incident has been reported to the Indian government and Tata’s clients.

Earlier this week, Reuters reported that ransomware group World Leaks had published more than 200,000 files on the dark web, including purported component design documents linked to Apple and Tesla. Reuters could not independently verify the authenticity of the leaked material.

Tata Electronics has acknowledged a “cybersecurity incident” but stated that its operations remain unaffected. However, the company has not disclosed additional details about the breach.

Security Measures Strengthened Across Operations

Following the incident, Tata Electronics implemented stricter security protocols across all its offices and manufacturing facilities.

Remote access to sensitive internal tools, including systems used for purchase orders and other critical business functions, is now limited to selected employees. Previously, access to these systems was available to a broader group of staff.

Although employees may continue working remotely, only authorised personnel can now access sensitive applications from outside company premises. The tighter controls apply across Tata Electronics rather than being limited to specific factories.

According to people familiar with the matter, the company has also introduced stricter controls governing access to its official network from external locations.

The forensic investigation remains ongoing.

Apple Working Closely With Tata

One industry official said Apple’s security team is working closely with Tata Electronics to implement both immediate and long-term cybersecurity measures following the incident.

Neither Tata Electronics nor Apple responded to Reuters’ requests for comment. Taiwan Semiconductor Manufacturing Company (TSMC), Qualcomm and the Indian Computer Emergency Response Team also did not respond.

Tata Electronics, established in 2020 under the leadership of Chief Executive Randhir Thakur, has become a critical part of Apple’s manufacturing expansion in India. The company manufactures iPhone components while also expanding into semiconductor production.

The cybersecurity incident presents another challenge for Tata Electronics, which has recently faced allegations concerning environmental contamination near one of its iPhone parts plants. Separately, its sister company, Jaguar Land Rover, experienced a cyberattack last year that disrupted production for six weeks.

Leaked Files Allegedly Include Multiple Technology Companies

World Leaks claims to have published more than 204,000 files containing over 630 gigabytes of Tata Electronics data.

Reuters previously identified purported Apple and Tesla documents within the leaked database. Further examination also revealed files apparently linked to TSMC and Qualcomm.

Among the documents were a 2022 file marked “TSMC Secret” that appeared to contain product reliability testing information, an Apple Silicon Engineering Group document from 2023 mapping Apple part numbers to TSMC components, and a purported Qualcomm engineering document containing confidential technical drawings.

Reuters could not verify the authenticity of the documents, and World Leaks was not available for comment through its dark web portal.

According to research firm Counterpoint, India is expected to produce 26% of the world’s iPhones in 2026, compared with just 6% four years earlier, underscoring the country’s growing importance in Apple’s global supply chain.
