In the last financial year, COVID-19 pandemic has driven Australians to depend on internet considerably – whether to work remotely, to communicate or to access any online services. This high-level dependence has presented hackers with opportunities to exploit the vulnerable targets in Australia.
On 15 September 2021, the Australian Cyber Security Centre (ACSC) published its annual cyber threat report for the last financial year from 1 July 2020 to 30 June 2021. The ACSC report underlines the key cyber threats affecting Australian systems and networks.

How ACSC helped government and other industry sectors?
To combat cyber threat and attacks, the ACSC has supported the government and major industry organisations, including the healthcare sector, to decrease the risk of nasty cyber-attacks against the COVID-19 vaccine launch. The ACSC provided threat intelligence sharing, technical advice and assistance, earlier cooperation with vaccine supply chain entities, and vulnerability scanning of research, biotechnology, health, logistics and transportation industry.
COVID-19 pandemic demonstrated the ways in which malicious cyber actors can take advantage of the crisis period by conducting phishing and cyber attacks against vulnerable entities. However, with the support of ACSC, the country is on its way to strengthen its cyber resilience.
