The Australian parliament said on Friday that its network of hackers had been hacked into an unspecified "security incident," announcing an investigation.
"Following a security incident on the computer network of parliament, a number of measures have been implemented to protect the network and its users," parliament authorities said in a statement.
Officials declined to comment on the nature of the security breach, and explained that there was no evidence of data breaches.
"We have no evidence to suggest that it is an attempt to influence the results of parliamentary operations or to disrupt or influence electoral or political processes," the statement said.
"Our immediate focus was on securing the network and protecting data and users," he said, and the network passwords were changed as a precautionary measure.
"There is no indication that government departments or agencies were targeted in such a breach," Prime Minister Scott Morrison said.
The Australian Signal Directorate confirmed that it was cooperating with the parliament to respond to the attack, indicating the involvement of sophisticated actors on the issue.
The national network "ABC" that the intelligence agencies are considering whether China or another government behind the attack.
"The Directorate and the Australian Cyber Security Center will continue to work with (Parliament) to determine the full size of this breach," a spokesman for the Signal Directorate told AFP.
