Horizon Media, a company involved in digital marketing and audience analytics, formally reported a data breach to state regulators in Indiana on May 6, 2026. The incident, which allowed unauthorized access to its network infrastructure, was first identified on January 9, 2026. This information comes from public filings made with state authorities.

The reported breach involved the exposure of several categories of sensitive personal data. These included individuals' Full Name, Email Address, Mailing Address, Date of Birth, Social Security Number, Financial Account Information, Payment Card Information, and Tax and Wage Documentation. The presence of such diverse and critical data types raises significant concerns for those affected.

Exposure of this information can lead to various risks, including identity theft, financial fraud, and unauthorized access to other personal accounts. Affected individuals might experience phishing attempts or other scams targeting their personal or financial security. Vigilance is crucial for anyone whose data was compromised.

If you receive a data breach notification from Horizon Media, it is important to act promptly. Consider placing a fraud alert or freezing your credit with the three major credit bureaus. Regularly review your financial account statements, credit reports, and explanation of benefits for any suspicious activity. Additionally, be cautious of unsolicited communications requesting personal information and ensure strong, unique passwords for all online accounts.

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.
