According to the latest report, factory workers brought unreleased iPhone parts to the black market for sale. In response, Apple took countermeasures to keep the iPhone highly confidential. In addition, Apple has reduced the number of employees responsible for preventing the leakage of factory parts, and instead focused on combating CAD drawings and schematic leaks.
The report pointed out that the leaked unreleased iPhone hardware sold at the black market several times the standard wage of the workers. Factory employees used various methods to smuggle the shell or parts from the iPhone factory. A particularly bad situation occurred in the iPhone 5C era. A worker opened a truck full of thousands of iPhone 5Cs. Not only that, but workers also tried to dig tunnels to steal iPhone parts in secret.
Over the past five years, Apple has steadily increased its efforts to prevent leaks. Apple implemented strict security measures on its contractor's factory, including adding metal detectors to employees to work and garbage. As part of the supplier agreement, the factory must have Apple security personnel inspect the factory at any time. In the event of a leak, the factory will be fined tens of millions of dollars.
In the 2017 outline report, an Apple executive said that more leaks are now coming from Apple's headquarters in Cupertino, California, rather than the supply chain. Apple now seems to have succeeded in reducing leaks from the supply chain in terms of hardware, but is still working to prevent CAD files from being photographed or distributed. With the improvement of security measures, Apple began to consider reducing the size of the new product security team. One way is to reduce the number of the team and keep the secret in the hands of fewer people.
