UPDATE: The Central District of California court entered Final Approval of Settlement for $1.3 Million Common Fund in Data Breach Class Action for Houser, LLP. Joe Lyon was appointed co-lead counsel in this case.

The Lyon Firm is investigating a data breach impacting hundreds of thousands of California residents. Houser LLP, a California-based law firm, said an inside network data breach occurred in May 2023 and possibly exposed the personal data of over 325,000 individuals.

What Happened at Houser LLP?

Houser, a firm that specializes in serving high-profile financial institutions, says some sensitive files were “copied and taken” from their network several months ago. The breach investigation was apparently not completed until January 18, 2024, according to a regulatory filing made public by the attorney general of Maine.

It is unclear why it took over 8 months to alert victims of the incident. In June 2023, “the unauthorized actor informed Houser that they deleted copies of any stolen data and would not distribute any stolen files,” yet individuals were not notified until 2024. When a data theft event happens, it is critical to take certain measures to mitigate the damage, but individuals cannot be proactive if they are unaware of a data security incident.

The company has concluded that an unidentified third party had “unauthorized access” to the systems between May 7 and May 9. Houser LLP disclosed the data breach which involves sensitive confidential information, including:

  • Name
  • Social Security Number
  • Tax Identification Number
  • Driver’s License Number
  • Medical Information
  • Financial Account Information
