If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On May 19, 2022, the domain gdctax.com.au appeared on a leak site operated by the ransomware group lockbit2. The listing states that internal files were taken during a ransomware incident, though the number of people affected and the precise contents of any data remain undisclosed in public reporting.
The event is one of many similar claims made by ransomware operators during this period. Its significance lies in the nature of the organisation involved and the type of records such entities routinely process.
What happened
gdctax.com.au was listed on the lockbit2 ransomware leak site on 19 May 2022. The group claims to have stolen internal data from the organisation. No further details on the timing of the intrusion, the method of access, the volume of material taken, or any ransom demand have been made public. The number of individuals potentially affected is recorded as unknown.
Who is lockbit2?
Lockbit2 is the name used by a ransomware-as-a-service operation that emerged in 2019 and became active through 2022. The group supplies encryption tools to affiliate attackers in exchange for a share of ransom payments. Its standard approach involves encrypting systems and then threatening to publish stolen files if payment is not received. The group has been linked to incidents across multiple countries and sectors, relying on a public leak site to pressure victims.
About gdctax.com.au
gdctax.com.au operates as an Australian tax and accounting service provider. Organisations of this type collect and store client financial records, tax returns, identification documents, and correspondence with revenue authorities. A breach at such a firm can expose sensitive personal and commercial information because these records are required for compliance and advisory work.
What was likely exposed
The only detail released is that internal files were allegedly exfiltrated. The exact categories of data, file counts, or time periods covered have not been disclosed. Firms in this sector commonly hold names, addresses, tax file numbers, bank details, income records, and business documentation. Without confirmation from the organisation or investigators, the specific contents of the claimed exfiltration remain unverified.
Why it matters
Exposure of tax and financial records can lead to identity misuse, fraudulent filings, or targeted scams against affected clients. For the organisation, the incident may trigger regulatory notification obligations under Australian privacy law and could affect client trust. Because the scale of the data and the extent of any subsequent misuse are not yet known, the practical impact on individuals cannot be quantified from available information.
If your data was in this claimed breach
Monitor bank and tax accounts for unusual activity and consider placing a fraud alert with relevant credit agencies. Review any correspondence from gdctax.com.au for guidance on next steps. Individuals can run a free exposure scan of their email address against known breach data sets to check for appearances in previously published records.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
