Google has confirmed that a breach of data occurred in its cell network provider, Google Fi. The breach is thought to be connected to a recent security compromise at T-Mobile, which exposed the personal information of millions of customers.
TechCrunch reports that an email was sent to Google Fi customers on Monday which said that Google Fi’s primary network provider had informed them of suspicious activity regarding a third-party support system containing a limited amount of Google Fi customer data.
Google Fi relies on both T-Mobile and U.S. Cellular for network coverage, making it likely that the breach is tied to T-Mobile’s recent hack. On January 19th, T-Mobile disclosed that the intrusion allowed access to the personal data of 37 million customers, including billing addresses, dates of birth, and account details. This marks the eighth time T-Mobile has been hacked since 2018.
As for the breach of Google Fi, the company stated that the hackers only gained access to limited customer information, such as phone numbers, account status, SIM card serial numbers, and information about mobile service plans. However, personal information, payment card data, passwords, PINs, or the contents of calls or text messages were not taken.
In the email, Google stated that it is working with the undisclosed network provider to secure the data and identify any potential impact on customers. The company also emphasized that the hackers did not access any of Google’s systems or any systems overseen by Google.
