The Australia Broadcasting Authority is conducting an investigation into recent hacker attacks to its Website following a security breach.
The ABA's Website was taken offline at 12:30pm last Thursday night after offensive material protesting against Internet censorship regulation was posted on the site.
The restored Website came back online around 4pm Friday afternoon, but the corrupted ABA homepage can still be viewed on several other Australian and offshore sites.
The attack was the second security intrusion in the last two weeks, according to Donald Robertson, ABA's media and PR manager.
"We're investigating the circumstances of the hacking and we will attempt to put in place procedures so it doesn't happen again," Robertson said.
Robertson said the ABA is working with Internet service provider, Magna Data on the investigation, but could not confirm whether the scrutiny would include a security audit of the Magna Data machine which hosts the Website.
Determination of the hacker's method of intrusion will be subject to the investigation, Robertson said, however, sources believe the hacker may have accessed the Website via FTP.
Due to similarities in tampering, Robertson said it is possible both security attacks may have been conducted by the same hacker.
According to Robertson, the ABA will not be taking measures to remove the offensive ABA homepage material from other Australian and offshore sites where it has also been posted.
