Why are Apple devices so highly regarded? Is it the cool design, the high-end device cachet or the fact that the operating system is proprietary and therefore more secure than others?

It’s probably a mix of all three. And certainly Apple’s security is much vaunted and its servers believed to be unhackable. Until recently.

A 16-year-old Australian high school student proved that nothing is impossible; he cracked Apple servers, downloaded around 90GB of secure files, including secure authorised keys used to grant login access to users, as well as accessing multiple user accounts.

The unnamed teen said he was a huge fan of Apple and he dreamed of working for the company.

But it wasn’t just a one-off hack; he broke into the servers numerous times and wasn’t detected.

However, when the tech giant finally noticed the intrusion it contacted the FBI which in turn took the help of the Australian Federal Police (AFP) after detecting his presence and geographical location.

The police swooped and seized two laptops, a mobile phone and hard drive and discovered the stolen data in a folder called "hacky hack hack."

The police also discovered a series of hacking tools and files that allowed the 16-year-old to break into Apple's mainframe repeatedly.

He also used WhatsApp to share his discoveries with others and has apparently garnered quite a reputation on the international hacking scene.

Investigators said his hacking methods "worked flawlessly" until the company noticed.

In a statement provided by Apple the company assured its customers that no personal data was compromised in the hack, though it is still unclear what kind of data the teen stole.
