Director-General ASD's review

I am pleased to present the 2022–23 Australian Signals Directorate (ASD) Annual Report.

ASD defends Australia from global threats, and advances the national interest through the provision of foreign signals intelligence, cyber security and offensive cyber operations, as directed by the Government. Throughout 2022–23, ASD continued this critical work with success.

ASD’s operating environment has remained complex and challenging during this reporting period, with Australia facing increased threats to national security, economic prosperity and social wellbeing from foreign interference, espionage and cybercrime.

ASD’s foreign signals intelligence operations support a range of activities that protect the lives of Australians. These include providing support to Australian Defence Force (ADF) operations across the globe, tracking the foreign communications of extremists who pose a threat to Australians and Australia’s interests, and supporting the safe release of Australians who have been taken hostage overseas.

ASD’s unique offensive cyber capabilities have been used to effectively counter offshore threats, including the dismantling of online infrastructure used by foreign cybercriminals targeting Australians. ASD also conducted a number of offensive cyber operations in support of the ADF.

In an environment where technology plays an increasing role in the daily lives of Australians, our cyber security functions continue to be critical in supporting national security and prosperity. Throughout 2022–23, Australia was targeted by a range of actors who conducted persistent cyber operations that posed significant threats to Australia, and we continued to observe an increase in the speed with which malicious actors have researched and then pivoted to exploit publicly released vulnerabilities.

Cybercrime continued to be a pervasive and endemic threat to Australia’s economic and social prosperity throughout 2022–23. Cybercriminals follow the money. Australia’s relative wealth, high levels of online connectivity and increasing delivery of services through online channels make it a very attractive and profitable target for cybercriminals. Ransomware is one of the most significant cybercrime threats Australian organisations faced, with modern ransomware attacks increasingly sequenced and orchestrated.

Throughout 2022–23, ASD has remained focused on these emerging cyber threats, including those to critical infrastructure and technologies, families and businesses.

A key priority for ASD during 2022–23 has been to continue its engagement with various parliamentary and other oversight bodies, including the Parliamentary Joint Committee on Intelligence and Security (PJCIS); Senate Standing Committee on Foreign Affairs, Defence and Trade; and the Joint Committee on Public Accounts and Audit; as well as the Inspector-General of Intelligence and Security (IGIS), and the Auditor-General – all of which provide assurance to the Australian public that ASD furthers the national interest while following the letter and spirit of the law. ASD also continued efforts to provide greater transparency of its activities through initiatives such as its proactive declassification program.

To support our analysts in an increasingly complex operating environment, ASD has focused on training and careers, modernisation of signals intelligence and cyber systems, and best-practice capability development. ASD has continued to expand its approaches to recruit and retain the workforce it needs.

ASD continues its focus on organisational governance and administration, ensuring that risk engagement, accountability and decision-making are fit for purpose.

An organisation is only as good as its people and the ASD senior management team is fortunate to lead a group of talented, dedicated people with diverse skills willing to overcome challenges in support of Australia’s interests.

I would like to finish by thanking the staff of ASD for their hard work and dedication over this year. ASD is a world-class intelligence, covert effects, and cyber security agency because of the talented, inventive and diverse people that make up our organisation.
