Mainstreet Wealth Management LLC, an Indiana-based financial advisory firm, officially reported a data security breach on July 7, 2026. This incident, which reportedly occurred on April 8, 2026, involves the unauthorized compromise of its network infrastructure. For clients, receiving a notification letter from Mainstreet Wealth Management LLC confirms that your personal information was exposed.
The compromised data in this incident is extensive and includes core financial identifiers. According to the notice, exposed records typically include your Full Name, Social Security Number, Financial Account Number, Date of Birth, Routing Number, Tax Return Information, Investment Portfolio Records, Home Address, and Phone Number. This combination of data types poses significant long-term risks.
Exposure of this information can lead to serious consequences for affected individuals.

Unlike passwords, financial identifiers cannot be easily changed, meaning the threat of exploitation can persist over time.

What to do if you were affected

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.
