TransUnion Says Hackers Accessed 4.4 Million Customers’ Data

Hackers accessed the personal information of more than four million TransUnion customers in July, according to a regulatory disclosure from the major credit reporting agency.

TransUnion said in Thursday filings with Maine’s attorney general’s office that the data of 4.4 million customers that had been stored “on a third-party application” was compromised on July 28. The company said it discovered the breach two days later and that “no credit information was accessed.”
