Walker Advertising LLC, a marketing services firm, officially reported a data breach incident to the Indiana Attorney General's office on June 5, 2026. This incident, which occurred on October 14, 2025, involved unauthorized access to the company's network infrastructure, leading to the exposure of various sensitive personal details.

The public filing indicates that the compromised data includes individuals' Full Name, Date of Birth, Email Address, Mailing Address, Phone Number, and Purchase and Order History. Additionally, exposed information extends to Password or Credential Hash data and Payment Card Information.

Such exposed data types can put individuals at risk for various forms of identity theft and fraud.

Password hashes, if improperly secured, might allow attackers to gain access to other online accounts.

Individuals who receive an official notification from Walker Advertising LLC regarding this breach should carefully review the details provided. It is recommended to monitor bank and credit card statements for any unusual activity. Consider changing passwords for online accounts, especially if you reuse credentials, and enable multi-factor authentication where available.

    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.
