Bieser Greer & Landis LLP (BGL) has disclosed a data breach involving unauthorized access to employee email accounts. The breach may have exposed names, Social Security numbers, and protected health information.
Bieser Greer & Landis LLP’s Data Breach Investigation
Bieser Greer & Landis LLP, a law firm headquartered in Dayton, Ohio, recently reported a data breach to the Massachusetts Attorney General’s Office. The firm confirmed that unauthorized actors gained access to internal email accounts containing sensitive personal data. Upon discovery, BGL launched a full forensic investigation and engaged external cybersecurity experts to assist with the response.
The investigation revealed that the unauthorized access involved email messages and attachments containing personally identifiable information (PII) and protected health information (PHI). The firm conducted a detailed manual review of the compromised data and, by December 11, 2025, determined that client and employee data had likely been exposed. Although there is no evidence of fraud or misuse so far, the firm has acknowledged that names and Social Security numbers were included in the exposed files.
To help mitigate potential fallout, BGL began notifying impacted individuals on January 8, 2026, and is offering complimentary identity theft protection services through IDX, a ZeroFox Company. Affected individuals are also being advised to take standard precautions such as monitoring financial accounts, reviewing credit reports, and placing fraud alerts or freezes as needed.
This breach highlights ongoing cybersecurity risks faced by professional services firms, especially those entrusted with highly sensitive personal and health-related information. Email-based breaches remain a common attack vector and often involve a broad range of data, placing individuals at elevated risk of identity theft.
