Sprint says hackers used Samsung’s website to access customers’ account information and data.

Yahoo! News reports that hackers were able to get into some Sprint accounts with a security loophole on Samsung’s “add a line” website.

Yahoo! News says hackers might have gotten customers’ first and last names, phone numbers, billing addresses, device type, subscriber ID, account number, account creation date, upgrade eligibility, add-on services, and more.

Sprint was made aware of the hack on June 22 and impacted users’ PIN numbers were reset.

The number of affected customers was not released, but Sprint did send out letters to subscribers who might have been impacted.

ZDNet reported that this is the second account breach of the year for Sprint. In May, Sprint was breached through Boost Mobile, a Sprint subsidiary.
