TransUnion LLC notified consumers in Vermont of a cybersecurity incident where unauthorized actors exploited a bypass in individual verification measures for direct-to-consumer products. Actors impersonated consumers using personal information from non-TransUnion sources to access the consumer portal. The incident affected individuals between December 1, 2022, and January 13, 2023. TransUnion stopped the bypass, conducted an investigation, and offered one year of complimentary credit monitoring.
