Securities Support Unit LLP, operating as Advisor's Advantage Network, reported a data security incident to Indiana authorities. This event, which occurred on March 19, 2026, was officially filed on July 31, 2026. The company stated that an investigation into the incident is currently ongoing.

The official filing indicates that a range of sensitive personal and financial information was exposed. Categories of data involved include Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Identification Number, Investment and Portfolio Details, and Mailing Address.

The exposure of such personal and financial identifiers can create risks for affected individuals. These risks primarily involve potential identity theft, financial fraud, and unauthorized access to personal accounts. People who received an official notification should review its specific details.

Individuals potentially affected by this incident are advised to monitor their financial accounts and credit reports for any unusual or unauthorized activity. Placing a fraud alert or security freeze with major credit bureaus can help prevent new accounts from being opened in one's name. It is also wise to be cautious of 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.
