Source code for a core component of the iPhone’s software has appeared online in what is described as “the biggest leak in history.”

iBoot, a part of iOS that ensures the device is booting a trusted operating system, was posted to GitHub anonymously. The code could be used by hackers to find vulnerabilities in Apple’s software. The company has already filed a copyright take-down request to have it removed.
