Mint Mobile has disclosed a new data breach that exposed the personal information of its customers, including data that can be used to perform SIM swap attacks.
"We are writing to inform you about a security incident we recently identified in which an unauthorized actor obtained some limited types of customer information," warns the Mint Mobile data breach notification.
While Mint has not disclosed details on how they were breached, the FalconFeeds threat intel service reported in July 2023 that a threat actor attempted to sell data on a hacking forum that was allegedly stolen from Mint Mobile and Ultra Mobile.
Mint Mobile previously suffered a data breach in 2021 when an unauthorized person accessed subscribers' account information and ported phone numbers to another carrier.
More recently, Mint's parent company, T-Mobile, suffered a massive data breach in January 2023 that exposed the data of 37 million accounts.
Xfinity discloses data breach affecting over 35 million people.
