The law firm Ulf Haldenstein Adler Freeman & Hertz LLP announced that the personal data of more than 3.4 million people were compromised in a cyber incident discovered in December 2023. Hackers accessed files containing names, social security numbers, medical records and other sensitive information. The company offers free credit monitoring services to victims, but does not disclose details of the attack or possible extortion.
Founded in 1888, the Wolf Hardenstein Law Firm is a well-known American law firm specializing in complex litigation, particularly in the area of securities and corporate law. It has offices in New York, Chicago, San Diego and Nashville.
The data breach is part of a troubling trend of attacks on large law firms and healthcare organizations that handle sensitive information. Although there is no evidence of a data breach, the scale of the breach calls into question the security of information even at large law firms. This incident highlights the need to strengthen cyber security and regularly monitor vulnerabilities.
