In response to a report in The Australian Financial Review, the Reserve Bank of Australia recently acknowledged in a statement that it has "on occasion been the target of cyber attacks."

The Australian Financial Review's Christopher Joye reported that the bank's computer networks "have been repeatedly and successfully hacked in a series of cyber-attacks to infiltrate sensitive internal information, including by Chinese-developed malicious software."

"After investigations by The Australian Financial Review, RBA officials disclosed that the central bank had been infiltrated by a Chinese-developed malicious software, or 'malware' spy program that was seeking intelligence on sensitive G20 negotiations," Joye writes. "Multiple computers within the RBA's network were compromised."

Still, the Reserve Bank of Australia stated in response, "The Bank has comprehensive security arrangements in place which have isolated these attacks and ensured that viruses have not been spread across the Bank's network or systems. At no point have these attacks caused the Bank's data or information to be lost or its systems to be corrupted. The Bank's IT systems operate safely, securely and with a high degree of resilience."

Reuters reports that information made available under the Freedom of Information Act reveals that the bank was hit by a malicious e-mail attack in November of 2011, which infected six workstations -- but the workstations didn't have local administrator rights, which prevented the malware from spreading.
