The teen, whose identity is being withheld, allegedly downloaded 90 gigabytes of secure files, along with accessing customer accounts over multiple occasions. When Apple noticed the intrusion, the company contacted the FBI, which in turn contacted Australian authorities.

During a raid at the teen’s home last year, Apple laptops, along with a phone and hard drive were seized, prosecutors said. The raid also uncovered on the teen’s computer hacking files and instructions located in a folder labeled “hacky hack hack.”
