On June 5, 2025, the small Australian accounting firm Ryan Harvie McEnery appeared on the leak site of the blacklock ransomware group. The firm, which provides taxation, superannuation, accountancy and valuation services to businesses and individuals, is claimed to have had internal files exfiltrated during a ransomware attack. Public reporting indicates the number of affected clients remains unknown, but any individual or family who used the firm’s services may have sensitive personal and financial records now in attackers’ hands.

What Public Reporting Shows
The breach involved internal files exfiltrated from Ryan Harvie McEnery, an Australian company with fewer than 25 employees and annual revenue under $5 million. The data was posted on the blacklock ransomware group’s leak site, accessible via the .onion link hosted on ransomware.live. Available reporting describes the incident as a ransomware attack in which the group first encrypted systems and then published a sample of stolen data to pressure the victim. No Reported Details have emerged on the exact volume or specific categories of client records exposed, though tax returns, superannuation documents, bank details and valuation reports are typical for such a firm.
Why This Matters for You and Your Family
If you or anyone in your household has ever engaged Ryan Harvie McEnery for tax preparation, superannuation advice or accounting help, your private financial information could be circulating among criminals. Taxation records, superannuation details and valuation documents often contain full names, addresses, dates of birth, tax file numbers, bank account information and family member details. Once exposed, this data can be sold, combined with other leaks, or used to file fraudulent tax returns, open accounts in your name, or target you with convincing phishing emails. For families, the risk extends to shared finances, joint tax filings and any children listed on those records.
The Doxxing and Identity-Chain Implications
Ransomware leaks like this one rarely stop at the initial data set. Criminals frequently cross-reference newly exposed tax files against other breaches to build detailed identity profiles. A single leaked tax return can link your name, address, phone number, email addresses and government identifiers. That information then chains to social-media handles, children’s school records, gaming usernames and family photos. The result is a complete roadmap for doxxing, identity theft, or targeted harassment. Credential leaks of this nature also cascade into account takeovers, especially for gaming accounts belonging to you or your children, where the same reused passwords or recovery emails appear.
