T-Mobile recently experienced a data breach in which some of its customers had their information, including “call-related information,” exposed to hackers.
In a notice on its website, the telecom giant said a security incident occurred that saw “customer proprietary network information” (CPNI) improperly accessed. Some of the CPNI may include “phone number, number of lines subscribed to on your account and, in some cases, call-related information collected as part of the normal operation of your wireless service,” T-Mobile said.
The company added the breach, reported to have impacted approximately 200,000 customers, did not include financial information, such as names on the account, credit card information, social security numbers, tax ID, passwords or PINs.
