Hamilton Capital LLC, an investment management and wealth advisory firm, filed a data breach notification with Indiana regulators on August 4, 2026. This filing details an unauthorized security incident that occurred on March 10, 2025, which compromised sensitive client information.

The publicly reported information indicates that the breach exposed a range of personal and financial data. This includes Full Name, Social Security Number, Financial Account Number, Date of Birth, Routing Number, Tax Return Information, Investment and Portfolio Records, Home Address, and Telephone Number.

Exposure of such sensitive information can create significant risks for affected individuals. Unauthorized access to Social Security Numbers and Dates of Birth could be used in attempts at identity theft. Compromised Financial Account Numbers and Routing Numbers could lead to unauthorized transactions or financial fraud.

Individuals who received a breach notification from Hamilton Capital LLC should immediately review their financial account statements and credit reports for any suspicious activity. It is recommended to place a fraud alert or consider freezing credit with major credit bureaus to prevent new accounts from being opened fraudulently.

Additionally, individuals should be cautious of unsolicited communications, especially those requesting personal or financial information. Regularly changing passwords for online accounts and enabling multi-factor authentication where available adds an extra layer of security.

This information is derived from official regulatory filings made public to inform affected parties. Understanding the specifics of such incidents helps individuals take appropriate measures to protect their personal and financial security.

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.
