Credit reporting giant TransUnion has disclosed a data breach affecting more than 4.4 million customers. The company filed a notice with Maine’s attorney general’s office on Thursday, attributing the July 28th incident to unauthorized access of a third-party application. This application stored personal data for TransUnion’s U.S. consumer support operations.
TransUnion claimed that no credit information was accessed but provided no immediate evidence to support this assertion. The data breach notice did not specify what types of personal data were stolen. A spokesperson for TransUnion did not immediately respond to requests for comment.
As one of the largest credit reporting agencies in the United States, TransUnion stores the financial data of more than 260 million Americans. This breach is the latest in a recent wave of hacks targeting U.S. corporate giants across various sectors. Recent victims include companies in the insurance, retail, and transportation industries.
Several other major companies, including Google, insurance giant Allianz Life, Cisco, and HR giant Workday, have recently reported data breaches involving customer data stored in their Salesforce-hosted cloud databases. Following its own breach, Google attributed the attack to an extortion group known as ShinyHunters.
It remains unclear who is behind the breach at TransUnion or if the hackers have made any demands to the company.
