The
comments came after Prime Minister Scott Morrison said a
"sophisticated state-based actor" had spent months trying to
hack all levels of the government, political bodies, essential
service providers and operators of critical infrastructure.
"We know it is a sophisticated state-based cyber actor because
of the scale and nature of the targeting," Morrison told
reporters but declined to say who Australia believed was
responsible.
Three sources briefed on the matter said Australia believed
China is responsible, however.
"There is a high degree of confidence that China is behind the
attacks," one Australian government source told Reuters, seeking
anonymity as he was not authorised to speak to media.
A Chinese Foreign Ministry spokesman on Friday denied Beijing
was involved and said China "firmly opposed all forms of cyber
attacks."
Australian intelligence has flagged similarities between the
recent attacks and a cyber attack on parliament and the three
largest political parties in March 2019. Last year, Reuters
reported that Australia had quietly concluded China was
responsible for that cyber-attack.
Australia has never publicly identified the source of that
attack, however, and China denied it was responsible.
As with last year's attack, Australia's chief cyber intelligence
agency said on Friday its investigation had found no evidence
that the perpetrator sought to be "disruptive or destructive"
once within the host network.
Morrison said he spoke about the issue with British Prime
Minister Boris Johnson on Thursday, while other allies have also
received briefings.
Defence Minister Linda Reynolds said advice showed no
large-scale personal breaches of data resulting from the attack,
but urged users to fully update web or email servers with the
latest software and use multi-factor authentication.
An Australian government source said Morrison's public
declaration was a bid to flag the issue to potential targets.
A U.S. security ally, Australia strained ties with its largest
trading partner, China, by pushing for an international inquiry
into the source and spread of the coronavirus that first emerged
in the central Chinese city of Wuhan late last year.
China recently imposed dumping tariffs on Australian barley,
suspended some imports of beef and warned its students and
tourists against travel to the country, citing racism
accusations. Two-way trade stood at A$235 billion ($162 billion)
last year.
