Man Group, a prominent global investment management firm, officially reported a data breach to the Indiana Attorney General on September 23, 2026. This disclosure stems from a security incident that occurred earlier, on March 28, 2026. The company handles extensive volumes of sensitive personal and financial data for its clients, making data security critical.

The compromised information includes very specific categories of data: Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Identification Number, Investment Portfolio Records, Home Address, and Email Address. This combination of details is particularly valuable to malicious actors for various forms of fraud and identity theft.

With data such as your Social Security Number, financial account numbers, and investment records potentially exposed, there is an elevated risk of severe financial and identity-related harm. This could include unauthorized access to your existing accounts, the opening of new fraudulent accounts in your name, or even complex tax identity theft that can be challenging to resolve.

Receiving a formal data breach notification letter from Man Group serves as official confirmation that your confidential information was involved in this security incident. This notification is important because it establishes your legal standing to understand what happened and to explore your options. It indicates that the company may have fallen short in protecting your data as required by law.

We encourage you to carefully read your notification letter from Man Group, noting any specific deadlines or offers of credit monitoring. While these offers can be helpful, they do not diminish your legal rights. Understanding the full implications of this breach and your legal standing is a crucial next step. An attorney can help clarify what the breach means for your individual situation.

If you have received a data breach notification from Man Group, it is important to assess your legal position.

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.

  • Secure your online accounts

    Change the password on any account that reused an exposed password and turn on two-factor authentication wherever it's offered.

  • 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.
