Google Fi confirms data breach, leaking millions of customer’s data

Google Fi, Google's cell network operator, has reportedly revealed a data breach, which is most likely related to the T-recent Mobile's security disaster, which allowed hackers to leak millions of customers' personal information.

The principal network provider for Google Fi allegedly alerted the firm that there was suspicious activity pertaining to a third-party support system storing a small quantity of Google Fi customer data, according to an email issued to consumers on Monday.

The alert's timeframe and the fact that Google Fi uses T-Mobile and the United States Cellular for network access makes it more likely that the cyberattack is connected to the recent T-Mobile hack.

This attack, which was discovered on January 19, provided hackers with a vast amount of personal information related to 37 million consumers, including dates of birth, billing addresses, as well as T-Mobile account information.

Apparently, T-Mobile has been the victim of eight hacking incidents since 2018.

As per sources, in the Google Fi breach, the hackers only gained access to a small amount of client data, including phone numbers, SIM card numbers, account status, and details of customers' mobile service packages, including international roaming or unlimited SMS.

According to Google, the hackers did not steal any of the users' payment card information, personal information, PINs, passwords, or the contents of text messages or calls.

While several emails notified consumers that no action is necessary, at least one Google Fi user posted in a Reddit post that their notice stated that SIM swapping, or temporarily taking over someone else's phone number, had occurred.

As per reports, Google informed the client that the unauthorized party held their phone number for about two hours and may have included the use of the mobile number to receive and send texts and make calls. Using this approach, hackers can access a victim's other internet accounts that are secured by the same mobile number, albeit one that has been taken over.
