What we know

Seyfarth Shaw LLP, a prominent law firm, filed a notice with the Texas Attorney General on September 21, 2026, regarding a data security incident that occurred on August 18, 2026. This notification confirms that unauthorized activity on the firm's systems led to the exposure of confidential personal information.

The compromised data includes highly sensitive categories such as Full Name, Social Security Number, Date of Birth, Home Address, Driver License Number, Financial Account Details, Tax Return Information, and Employment and Compensation Records. The presence of these specific data types presents a significant and long-term risk to affected individuals.

Attackers who obtain this type of information commonly use it for various forms of identity theft and financial fraud. This could involve opening new lines of credit, filing fraudulent tax returns, or accessing existing accounts. Since credentials like Social Security Numbers and Dates of Birth are permanent, the risk of misuse can persist indefinitely.

Under Texas state law, Seyfarth Shaw LLP had an obligation to implement robust security measures to protect the sensitive personal information it held. The occurrence of this data breach suggests potential gaps in those protective measures, leading to the unauthorized access and exposure of your data.

If you received a notification letter from Seyfarth Shaw LLP, it is crucial to act promptly. We recommend reviewing the notice carefully, monitoring your financial accounts and credit reports for any suspicious activity, and considering placing a fraud alert or credit freeze with credit bureaus.

Receiving an official data breach notification establishes your standing to seek legal recourse. You do not need to wait until you suffer financial losses to take action. If your information was compromised in this incident, you may be entitled to compensation. Contact us for a free, no-obligation case review to understand your rights.
