Apple reassures customers after Australian media reports that a teenager hacked into the company's network.

(Reuters)- Apple said on Friday that customer data was not compromised after Australian media reported that a teenager pleaded guilty to hacking into the US tech giant's main network, downloading internal files and accessing customer accounts.

A 16-year-old boy from Melbourne hacked into Apple's mainframe from his home multiple times over the course of a year, The Age reported, citing statements from the teenager's lawyer in court.

The teenager downloaded 90 gigabytes of secure files and accessed customer accounts without being identified, the newspaper said.

Apple contacted the FBI when it became aware of the intrusion, The Age reported, citing court statements. The FBI then referred the matter to the Australian Federal Police (AFP).

The report said that an AFP search and seizure operation at the boy's family home found two laptops, a cell phone, and a hard drive compatible with the intrusion reported by Apple.

According to the police report, the boy boasted about his activities on the WhatsApp messaging app.

An Apple spokesperson said the company's information security team "discovered the unauthorized access, contained it, and reported the incident to the police," without commenting further on the specifics of the case.

"We want to assure our customers that at no point during this incident was their personal data compromised," the spokesperson said.

AFP declined to comment because the matter was in court. A court spokeswoman declined to comment, other than to say that the teenager would be sentenced on September 20.

The boy's name was not released because he is a juvenile offender.
