The home of an infamous teenage computer hacker, known online as Abdilo, has been searched by Australian law enforcement authorities in a pre-dawn raid.

As reported in January by the ABC, Abdilo regularly boasted of his hacking exploits online — claiming responsibility for breaching the systems of Australian travel insurance company Aussie Travel Cover.

Technology security experts described the hack as one of the largest privacy breaches in Australian history.

He also claimed he was responsible for hacking into a website run by the Australian Nuclear Science and Technology Organisation (ANSTO), local government websites and Australian universities.

In February thousands of students from the University of Sydney received an email from the dean of the arts and social science faculty to notify them that, due to a security breach, their personal information may have been compromised.

An AFP spokesperson confirmed to the ABC search warrants were recently executed in Queensland as part of an "ongoing investigation" into the hacking incidents.

The police would not comment further, saying the investigation is still ongoing.

The ABC learnt of the raids via Abdilo, who is known online under other pseudonyms such as Notavirus, Surivaton and Grey Hat Mafia's Bitch.

It was his Grey Hat Mafia's Bitch account that he used to post a message to a public online discussion board known as Hack Forums that he had been served the warrant.

"When I got raided I was served a 3LA order to hand over my passwords," he wrote.

Under the Crimes Act, Section 3LA gives police the ability to get an order from a magistrate that compels a suspect to give police their passwords and decryption keys.

If the person served the order refuses, the maximum penalty is up to two years jail.

The post, however, has since been deleted by the Grey Hat Mafia's Bitch account.

On Thursday, the post outlining the details of the raid was replaced with a long string of random letters.

Abdilo appears to be an infamous character in the hacking community.

One user of the forum — when discovering Grey Hat Mafia's Bitch was Abdilo — wrote, "oh you're abdilo LOL when did [the raid] happen?".

Abdilo claims responsibility for largest hack in Australian history

In an online interview in January, Abdilo told the ABC in January he had hacked the systems of Aussie Travel Cover.

He claimed he had the private details of hundreds of thousands of people.

Aussie Travel Cover was aware of the hack, but opted not to inform insurance policy holders or customers that their private details might have been stolen.

In the days after the story was published, Abdilo went on a hacking spree — and in one case streamed his attacks live on the internet.

So far no investigation into the incident has been launched by Australia's privacy watchdog.

In early March, the office of the Australian Privacy Commissioner told the ABC "we are considering the information that Aussie Travel Cover has provided us about the data breach".
