Why you received this letter
Infillion Inc. appears to be a technology company specializing in digital advertising, data-driven marketing, and consumer analytics. As a firm operating in the ad-tech space, Infillion typically collects and stores vast amounts of consumer data, including digital identifiers, browsing habits, contact information, and behavioral profiles used for targeted advertising campaigns. This security incident was officially reported to the Indiana Attorney General in 2026, confirming that the company's systems were compromised. If you have received a formal data breach notification letter from Infillion, it indicates that your personal information was likely stored within their digital infrastructure at the time of the unauthorized access. We recommend reviewing the letter carefully to understand exactly what information was exposed and to monitor your accounts for any suspicious activity.
What to do after the letter
Confirm the notice is genuine
A legitimate Infillion Inc notice references the specific incident reported to the Indiana Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
