Seyfarth Shaw LLP, an internationally recognized AmLaw 100 corporate law firm, filed a report with the California Attorney General's office on September 18, 2026, detailing an unspecified data security incident. The firm stated that this event, which occurred on or about August 18, 2026, is currently under monitoring to assess its full scope and impact.

The breach involved the potential exposure of several categories of personal data. According to the firm's filing, the compromised information includes 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 exact nature of how unauthorized access occurred was not specified in the public filing.

Exposure of these types of core personal identifiers carries significant risks for affected individuals. The combination of Social Security numbers, dates of birth, and financial details can make individuals vulnerable to various forms of identity theft, fraudulent financial transactions, or unauthorized access to other personal accounts. Such compromises often necessitate long-term vigilance to detect and mitigate potential misuse of information.

If you have received an official notification letter from Seyfarth Shaw LLP regarding this incident, it is important to review its contents carefully for specific instructions. As general protective measures, consider monitoring your credit reports regularly for any unauthorized activity, placing fraud alerts or security freezes on your credit files, and carefully reviewing all financial statements and explanations of benefits for unusual charges or services. Be cautious of any unsolicited communications that request personal information, as these could be phishing attempts.

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.
