TransUnion, a credit reporting giant, discloses data breaches that affect the personal information of more than 4.4 million customers.
In a filing Thursday with the Maine Attorney General's Office, Transunion attributed the July 28 violation to unauthorized access to third-party applications that store customer personal data for its U.S. consumer support business.
Transunion claimed that “credit information was not accessed,” but did not provide immediate evidence of that claim. The data breach notification did not specify that certain types of personal data were stolen.
Transunion spokesman David Blumberg did not immediately comment when contacted by TechCrunch.
Transunion is one of the largest credit reporting agencies in the United States and stores financial data from over 260 million Americans. It is the latest American company giant to be hacked in recent weeks following a wave of hacking targeting the insurance, retail, transportation and aviation industries.
Several companies, including Google, Insurance Giant Allianz Life, Cisco and HR Giant Work Days, have reported data breach of customer data stored in the Salesforce host's cloud database. Following that violation, Google attributed the hacking to a group of terrors known as Shinyhunters.
It is not clear whether the person behind the Transunion violation, or the hackers made the request from the company.
