US mobile network operator Sprint said hackers broke into an unknown number of customer accounts via the Samsung.com. The personal information that have been viewed includes the following: phone number, device type, device ID, monthly recurring charges, subscriber ID, account number, account creation date, upgrade eligibility, first and last name, billing address and add-on services. Sprint said the information hackers had access to did not pose a substantial risk of fraud or identity theft, although, many might disagree with its assessment. The company said it re-secured all compromised accounts by resetting PIN codes, three days later.

The California Office of the Attorney General reported a data breach involving Sprint on September 20, 2017. The breach occurred between May 7 and July 22, 2017, potentially compromising customers' Sprint account Personal Identification Number (PIN) and security questions/answers. The number of individuals affected is unknown.
