If you have received a data breach notification letter from Seyfarth Shaw, it indicates that your personal information was potentially compromised. This letter serves as their formal acknowledgment that an unauthorized party gained access to systems containing sensitive data entrusted to the firm.

The exposed data categories include your Full Name, Social Security Number, Date of Birth, Home Address, Driver's License Number, Financial Account Details, Wage and Compensation Information, and Confidential Legal and Personnel Records.

Law firms like Seyfarth Shaw hold vast amounts of highly sensitive client and employee data, making them prime targets for cybercriminals. Under Indiana law and established legal principles, organizations are obligated to implement robust security measures to protect this information.

Upon receiving a notification letter, it's crucial to act. Carefully review the letter to understand what specific data types of yours were exposed. Consider placing a fraud alert or freezing your credit with the major credit bureaus. While the letter may offer credit monitoring services, these are often limited. It's also wise to monitor your financial accounts and explanation of benefits statements closely for any suspicious activity.

Receiving a breach notification letter grants you legal standing. Even if you haven't yet experienced direct financial loss, the increased risk of future harm, and the time spent monitoring your identity are recognized as damages.

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.

  • Replace exposed ID documents

    Contact your state DMV or the issuing agency about replacing an exposed driver's license, passport, or government ID number.

  • 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.
