A recent severe cybersecurity incident at an Indian factory has created an unprecedented breach in Apple’s carefully maintained secrecy. Tata Electronics, India’s largest Apple contract manufacturer, was hit by a ransomware group called World Leaks, with approximately 630GB of data—over 200,000 confidential documents—posted on the dark web. Unlike past leaks of dubious authenticity, these materials have been verified as genuine by both AppleInsider and Reuters, including motherboard schematics for the iPhone 18 Pro, Apple silicon data sheets, and supplier cross-reference lists that are never publicly disclosed. This means the iPhone 18 Pro’s hardware design and supply chain structure were already exposed two months before its official release.
Tata of India Breached by World Leaks: 630GB of Confidential Data Leaked, iPhone 18 Pro Real Device Motherboard Schematics Fully Exposed
Tata Electronics is the electronics manufacturing arm of the Tata Group, which has rapidly emerged in recent years as Apple’s core supplier in India, handling both component production and iPhone assembly. On June 22, 2026, Reuters was the first to report that Tata suffered a cyberattack, with the hacker group World Leaks claiming to have stolen large amounts of confidential data. Subsequently, over 200,000 documents totaling approximately 630GB were posted on the dark web.
Initial analysis of the leaked documents confirms they contain logic board schematics for the iPhone 18 Pro and iPhone 18 Pro Max, datasheets for several Apple-designed chips, and internal Apple part number documentation for all iPhone 18 Pro components. AppleInsider notes that these schematics were created using Siemens NX software and possess all the typical characteristics of Apple design documents, confirming their authenticity.
Reuters’ in-depth report on June 29 further revealed that at least six documents in the leaked files individually mapped hundreds of iPhone 18 Pro components to specific suppliers. Additionally, the folder also contained early photos of the iPhone undergoing drop tests at Tata’s factory, with the shooting date marked as early 2026.
In addition to Apple, Tesla was also a victim with some of its confidential information being leaked.

What the leaked documents revealed: A20 Pro, C2 baseband, and complete supplier map
According to AppleInsider’s analysis, several key pieces of information emerged from the leaked Tata documents. First are the logic board schematics for the iPhone 18 Pro and Pro Max, detailing every layer of the motherboard layout, chip positions, and their supplier sources. Next is the datasheet for Apple’s A20 Pro chip, codenamed “Borneo,” manufactured using TSMC’s 2nm process, with expected upgrades in the Image Signal Processor (ISP) and display security.
Third, the document contains information about Apple’s self-developed C2 baseband, codenamed “Ganymede”. This aligns with January 2026 rumors, indicating that the iPhone 18 Pro will use Apple’s own baseband, officially ending its 15-year dependence on Qualcomm.

AppleInsider also noted that Tata’s security measures are actually quite strict. In the leaked parts configuration documents, information such as color options was redacted due to NDA confidentiality clauses, which is even more cautious than the practices of Apple’s other major supplier Foxconn. Additionally, most high-quality drop test images and videos actually featured current models like the iPhone 17 Pro or iPhone 15, not the iPhone 18 Pro. The attackers may have deliberately chosen to release older documents first to retain leverage in negotiations with Apple and Tata.
Three Major Supply Chain Shifts: Samsung Expands, Qualcomm Exits, India Share Climbs
By cross-referencing the leaked supplier comparison table with multiple reports, three notable changes have emerged in iPhone 18 Pro’s supply chain structure:
First, Samsung’s share continues to expand:Regarding memory, Apple has allocated 60% to 70% of its LPDDR5X orders for the iPhone 17 series to Samsung, with SK Hynix and Micron as backup suppliers.TrendForce This trend was already noted in reports from late 2025. What makes this even more noteworthy is that Samsung is entering the iPhone CMOS image sensor supply chain, which was previously monopolized by Sony. Samsung is setting up production lines at its Taylor, Texas factory to develop 3-layer stacked hybrid bonding CIS sensors for the iPhone 18 series. It is rare in Apple’s supply chain for a single supplier to secure both the main memory and image sensor orders.
Second, Apple fully replaces Qualcomm with its self-developed C2 baseband:iPhone 18 Pro and Pro Max will feature the C2 baseband chip codenamed Ganymede, marking Apple’s first complete abandonment of Qualcomm baseband chips on flagship iPhones. This will further erode Qualcomm’s share in the iPhone baseband business, representing a key step in Apple’s effort to end its 15-year reliance on Qualcomm.

Third, India’s share of assembly is rising rapidly:According to multiple industry analyses, India is expected to assemble approximately 28% of global iPhones in 2026, up from 23% in 2025 and 14% in 2024. Apple’s iPhone production in India grew by approximately 53% last year, assembling roughly 55 million units. Tata’s upgrade from component supplier to core assembly partner is precisely the epitome of this supply chain shift. Ironically, it is this expansion of Tata’s role that makes it a more valuable target for hackers.
The Cost of the Confidentiality System
The Tata hack exposed a harsh reality: as Apple diversified its supply chain into India, it also spread its confidentiality responsibilities across more links. Tata’s security measures were already rigorous, but in today’s era of increasingly professional ransomware groups, a single compromised node can lead to leaks of sensitive information across the entire production line. For Apple, this isn’t just a PR crisis—it’s a fundamental challenge to supply chain governance. When the iPhone 18 Pro officially launches in September, the outside world will for the first time ever have advance access to the complete hardware design and supply chain map. Apple’s carefully cultivated “element of surprise” may already be gone.
