A High School student from Melbourne, Australia, hacked into the servers from Apple. He did this repeatedly and he succeeded in downloading 90GB of highly secure files.
The boy started at age 16 and continued hacking for some time. He even accessed customer accounts. Apple finally found out about this unauthorized access and they made contact with the FBI. They traced it down to Australia where the local Federal police joined them with the search after the boy.
The teen was clever enough and knew he would be traced down if he wouldn't use tools, like VPNs, to avoid that. After some time Apple traced down the serial numbers of the MacBooks used.
The teen will be sentenced next month, and he has pleaded guilty. His lawyer said he hacked into Apple's servers because he really liked the company and wanted to work there. He tried to get recognised by what he did, but it’s certain Apple will not see this the same way.
UPDATE: Apple has confirmed no personal data was taken in this hack. Readmorehere.
