neffendorfblockercpa.com Listed by Threeam Ransomware Group

On February 18, 2025, the Texas accounting firm Neffendorf & Blocker, PC appeared on the leak site of the threeam ransomware group. The firm, which serves clients across the Texas Hill Country, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of affected individuals remains unknown, any client whose tax documents, financial records, Social Security numbers, or contact details were stored in those systems may now have their personal information in the hands of criminals.

Reported Details from Reports

Public reporting indicates that Neffendorf & Blocker suffered a ransomware intrusion in which attackers copied internal files before encrypting systems. The data was later published on the group’s dark-web leak site. Available reporting describes the exposed material as internal business files typical of an accounting practice, which often contain client names, addresses, dates of birth, tax returns, bank account information, and employer identification numbers. No confirmed total of records or clients has been released by the firm or the attackers.

February 18, 2025 marks the date the sample data and extortion notice went live on the threeam leak portal. The firm’s own website emphasizes its focus on personal attention to clients and states that it values privacy highly, yet the breach demonstrates how even smaller regional practices remain targets.

Why This Matters for You and Your Family

If you or anyone in your household has used Neffendorf & Blocker for tax preparation, bookkeeping, payroll, or estate planning, your sensitive financial and identity information could be exposed. Criminals routinely sell or auction such data on underground forums, where it can be combined with other leaks to build complete profiles. For ordinary families this often leads to tax-refund fraud, unauthorized loans opened in your name, or sudden spikes in identity-theft activity that can take years to untangle.
