Computer networks at the Reserve Bank of Australia have been hacked, some reportedly by Chinese-developed malware searching for sensitive information, officials said Monday. The central bank revealed the attacks after investigations by The Australian Financial Review found multiple computers had been compromised by malicious software seeking intelligence. The newspaper said in one attack a Chinese-developed malware spy programme was searching in 2011 for information on sensitive G20 negotiations, where Beijing’s exchange rate and currency reserves were on the agenda.
