Seyfarth Shaw LLP, a prominent corporate law firm, recently notified individuals about a data security incident that occurred in August 2026. This notification, sent out in September 2026, indicates that an unauthorized party gained access to their systems. Given the highly sensitive nature of information managed by a law firm, such incidents warrant immediate attention from those affected.

The compromised data includes critically sensitive details such as your Full Name, Social Security Number, Date of Birth, Home Address, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, and Employment Records. The exposure of these core identity and financial records can significantly increase your risk of identity theft, various forms of fraud, and unauthorized financial activities.

If you received a notification letter from Seyfarth Shaw LLP, it's important to act proactively. Carefully review the letter for specific instructions. We recommend immediately placing a fraud alert or freezing your credit with the three major credit bureaus (Equifax, Experian, and TransUnion) and continuously monitoring your bank statements, credit card activity, and any explanation of benefits for suspicious transactions.

Under California law, companies like Seyfarth Shaw LLP have a responsibility to protect the personal information they hold. Receiving this notification confirms that your data was indeed compromised due to a security lapse. This official acknowledgment is an important step in understanding your rights and options following such an event.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
