Australia's cyber intelligence agency detected an attack on the national parliament’s computer network and believes that a sophisticated state actor is responsible, Prime Minister Scott Morrison stated. Networks of main political parties have also been affected. Morrison did not name any suspects or reveal what information was accessed, but did state that there was no evidence of election interference. Cybersecurity researchers consider China, Russia, and Iran the most likely culprits. China has denied the allegations since.
Cyber-attacks can have a background in international relations, or bring about the consequences that can escalate to a political and diplomatic level. An increasing number of states appear to be developing their own cyber-tools for the defense, offence and intelligence related to cyberconflict.
The use of cyber-weapons by states - and, more generally, the behavior of states in cyberspace in relation to maintaining international peace and security - is moving to the top of the international agenda.
