Indonesian hackers have attacked the website of the Australian Secret Intelligence Service (ASIS), according to hackers and cyber experts cited by the Sydney Morning Herald.

The attack was confirmed by Heru Sutadi, executive director of Indonesian technology think tank the Indonesia ICT Institute, according to the report.

He said hackers from the country had launched a successful "distributed denial of service" attack, which started last Friday and were linked to hacktivist group Anonymous. The ASIS site was still not working on Monday evening.



Several Indonesian hacker groups were also boasting of the cyberattack on online forums, he noted, such as the Indonesian Security Down Team.

The attack comes nearly a week after a group calling itself Anonymous Indonesia claimed to have attacked over 170 Australian sites--mainly belonging to small busineses such as a bouncy castle company and a dry cleaner, noted BBC News.



This was apparently in response to reports of Australia's alleged electronic spying operations from its Jakarta embassy, which were based on U.S. National Security Agency documents leaked by whistleblower Edward Snowden. The hackers are calling for an apology from the Australian government and its promise to stop the electronic surveillance program.



Last week, Anonymous hacked the Singapore Prime Minister's site following his vow to "track down" hackers who targeted the country. This was the first time he had responded to earlier threats by a hacker called "The Messiah" and part of the Anonymous group, who posted a YouTube video in protest of the Singapore government's online media licensing rule .
