TransUnion Reports Data Breach Affected Personal Information of 4.4 Million Customers
TransUnion, a prominent credit reporting agency, has announced a data breach affecting the personal information of over 4.4 million customers.
In a statement to Maine’s attorney general on Thursday, TransUnion revealed that the breach occurred on July 28 and was caused by unauthorized access to a third-party application that stores customer data for its U.S. support operations.
Although TransUnion claimed that “no credit information was accessed,” they did not provide immediate evidence to back this assertion. The breach notification did not specify which types of personal data were compromised.
David Blumberg, a spokesperson for TransUnion, was unavailable for comment when contacted by TechCrunch.
As one of the largest credit reporting agencies in the United States, TransUnion manages financial records for more than 260 million Americans. This incident adds to a growing list of corporate breaches affecting major U.S. companies, following a recent uptick in cyberattacks on sectors like insurance, retail, and transportation.
Numerous companies, including Google, Allianz Life, Cisco, and Workday, have reported data breaches involving customer information stored in Salesforce-hosted cloud environments. Following its own breach, Google associated the attacks with a threat group known as ShinyHunters.
The identity of those responsible for the TransUnion breach remains unclear, as does whether any demands were made to the company.
