APRA Decommissions D2A System Due to Security Vulnerabilities
Summary
The Australian Prudential Regulation Authority (APRA) has decommissioned its Direct to APRA (D2A) data submission system due to identified security vulnerabilities. APRA is accelerating its transition to the APRA Connect portal and has provided interim instructions for data submissions.
What changed
APRA has permanently decommissioned its legacy Direct to APRA (D2A) data submission system, effective March 20, 2026, following the discovery of security vulnerabilities during a penetration test on March 19, 2026. This action is precautionary and aims to mitigate risks to APRA and regulated entities. APRA is accelerating its program to migrate all data collections to the APRA Connect portal, which offers enhanced security features.
Organisations that used D2A are instructed to immediately uninstall the D2A client to mitigate residual risk and review their own system and data security measures. For interim data submissions due before the full migration to APRA Connect, entities should complete files using normal protocols (XML or XBRL preferred) and contact dataanalytics@apra.gov.au for secure submission instructions. APRA will provide further guidance on the transition to APRA Connect.
What to do next
- Immediately uninstall the D2A client.
- Review system and data security measures.
- Contact dataanalytics@apra.gov.au for instructions on secure data submission for interim filings.

Direct to APRA security update and accelerated decommission
Friday 27 March 2026
Print Email The Australian Prudential Regulation Authority (APRA) has decommissioned its legacy Direct to APRA (D2A) data submission system for entity access. The system was taken offline on Friday 20 March following the identification of security vulnerabilities through a routine penetration test on Thursday 19 March.
APRA is accelerating its program to transition all APRA’s data collections onto the singular interface of APRA Connect.
This action is precautionary and in line with APRA’s low risk tolerance for system vulnerabilities that may expose APRA or regulated entities to attack. APRA is not aware of any security breaches or exploitation on APRA’s systems.
Preventative security action
Organisations that use D2A should take additional measures as a precaution:
- Immediately uninstall the D2A client. The presence of the D2A program could pose a residual risk. Removal is advised to protect your organisation’s data integrity and security.
- Review system and data security measures and undertake additional checks as a preventative measure.
Meeting reporting obligations
APRA is expediting its multi-year program to migrate all data collections from D2A to the APRA Connect portal, which includes enhanced user experience, performance and security features.
APRA has also put in place arrangements to ensure continuity and security of the data we collect on behalf of industry, and for other agencies and the public.
For an interim period, organisations with data submissions due are instructed to:
- Complete their files as per their normal protocols in the lead up to the due date of their submission. XML or XBRL files are preferred.
- Contact dataanalytics@apra.gov.au for instructions on how to securely submit these files. APRA will provide further information in due course about the program to move all data collections to APRA Connect.
D2A and APRA Connect enable financial institutions to lodge entity information and regulatory data to APRA. APRA Connect has a superior user interface as well as operational and security characteristics. The move to a singular system for data collection will improve the experience for entities over the long term, while reducing costs and managerial complexity.
