AppleInsider can exclusively confirm that logic board designs for the iPhone 18 Pro, along with A20 Pro data sheets, were among the files stolen from Tata’s India facility.

On June 23, it was reported that Tata, an Apple supply chain partner, had been the target of a cyberattack in India. Tata, along with Foxconn, produces iPhone components and assembles models like the iPhone 17 Pro.

More than 630GB of confidential data was stolen from Tata, a large portion of which is related to Apple products. As initial reporting revealed virtually nothing about the scope of the attack, AppleInsider has now conducted a preliminary analysis of the files taken from Tata.

iPhone 18 Pro and iPhone 18 Pro Max logic board schematics, along with data sheets for multiple Apple-designed chips, including the A20 Pro, were obtained by the attackers. Additionally, documentation containing all Apple part numbers for iPhone 18 Pro components is present.

AppleInsider can confirm the authenticity of the iPhone 18 Pro schematics and data sheets, as they have all the hallmarks of authentic Apple design documentation. As with most Apple schematics, many of the documents were created with Siemens NX.

The schematics themselves reveal the exact board layouts for the iPhone 18 Pro and iPhone 18 Pro Max, with detailed information on the individual chips, including the companies that supply them. Different layers of the logic boards are all detailed and shown in multiple angles.

Data sheets related to the A20 Pro chip, codenamed Borneo, offer an idea of the improvements it might offer relative to the A19 Pro. While performance upgrades are guaranteed, the available documentation suggests Apple’s new chip will offer an improved Image Signal Processor and enhanced display security.

Additionally, documents related to Apple’s C2 modem, codenamed Ganymede, suggest the hardware will see use in the iPhone 18 Pro. This information lines up with rumors from August 2025 and January 2026.

Though a variety of files related to the upcoming iPhone 18 Pro and iPhone 18 Pro Max, known as V63 and V43, respectively, were taken, few contain new information.

Aside from one reference to the iPhone Fold, which bears the identifier V68, none of the Tata documents appear to have information about upcoming Apple products beyond the iPhone 18 Pro and iPhone 18 Pro Max.

The documentation taken from Tata overwhelmingly includes files related to quality control, hardware testing, NonUI builds of iOS, assembly lines, and more. Though high-quality imagery and drop test videos are present, all of them are of the current iPhone 17 Pro or of the base model iPhone 15.

Still, two videos reveal an interesting detail about how Apple’s artwork is guarded. During the development of the iPhone 17 Pro, boxes with decoy or test designs were created. They feature an iPhone with the camera bump of the M4 iPad Pro, creating a product that does not exist in reality.

While we won’t link to any of the files taken from Tata, the videos of placeholder box art have since been posted to X by Apple prototype enthusiast and researcher MWR.

Before the release of the iPhone 17 series, Apple would send out 17 Pros in decoy boxes to employees that pictured an iPhone with an iPad Pro camera bump and no Apple logo. Reminiscent of the PROTO1 iPhone 16 design.

While placeholder logos and artwork are often used to prevent leaks, test equipment, and train workers, these printed mockups rarely surface in video form. Apple’s test logos have appeared on prototype hardware, though.

Overall, the Tata cyberattack was one that delivered quantity over quality, in terms of the files taken. Those behind the attack acquired a variety of files, but very few of them are actually useful to anyone beyond Tata itself.

Based on the available information, it looks as though Tata took unusually strict preemptive measures to ensure that information about the iPhone 18 Pro and iPhone 18 Pro Max does not get compromised.

Files that list the individual parts and configurations, for instance, have color options redacted due to NDAs in place. These are security measures that even Apple’s main supply chain partner, Foxconn, hasn’t always used.

It’s also possible that the group behind the cyberattack opted to manually remove information and files that would be of significant concern to Apple and Tata. By releasing files related largely to the iPhone 17 Pro, the attackers can show off their skills while still maintaining leverage against Apple and Tata with iPhone 18 Pro documents.

Still, given the presence of iPhone 18 Pro logic board schematics, it’s unlikely the hackers went through the trouble of cherry-picking documents related only to the iPhone 17 Pro and iPhone 15.

Relative to the May 2026 cyberattack that targeted Foxconn facilities in North America, the attack against Tata yielded more useful information, but not by much.
