  • The breach resulted in hackers obtaining limited customer information such as account status, phone numbers, and information about mobile service plans. However, payment card information, PINs, passwords, calls, and text messages were not compromised.
  • Google is working with an unnamed network provider to determine the cause of the breach and prevent future incidents from occurring.

Google has confirmed more than ever a recent information breach affecting Google Fi phone network customers. It is likely related to a security incident at T-Smartphone, where hackers stole millions of customers’ information.

Google Fi operates as a Mobile Virtual Network Operator (MVNO)Actually, , which acts like a regular cell network provider. Indeed, MVNOs are more budget-friendly phone plans than typical phone plans. But don’t have theirtheyown network infrastructure.

Interestingly, For example, Google Fi relies on T-Smartphone’s infrastructure. And since it was compromised, Google Fi was also impacted. However, it’s noting that Google Fiworthis not directly related to Google’s mobile operating system, Android.

Below is a snippet from email that Google sent to Fithesubscribers. Howeverit, affected only a limited amount of information.

It’s worth noting that The T-Cellphone breach incident

As you may know, The timing of this revelation and the fact that Google Fi uses U.S. Cellular and T-Smartphone for network platform indicate a connection to the T-Smartphone hack. Actually, The incident came to light on January 19, when hackers stole 37 million customers’ personal information, such as user ID of birth, billing addresses, and other T-Portable device dates details. It was the eighth hacking incident at T-Cellphone since 2018.

According to Google, hackers may have obtained limited customer information such as login status, phone numbers, SIM card serial numbers, and information about the customers’ portable device utility plans from the breach.

Yet, they didn’t take facts like payment card information, PINs, passwords, calls, ortext messages. Unfortunately, the extent of the breach is unclear as Google doesn’t reveal the number of cell subscribers it has.

Most of the emails sent to customers claimed that no action was necessary. However, one Google customerFion Reddit reported the, incident of their phone number getting hijacked also known as SIM swapping.

Apparently, the hackers controlled their number for nearly two hours and could have used it to send and receive texts and calls. Usually, hackers employ this method to access a victim’s other online accounts that utilize the same phone number.

In its, Google has a reputation for offering “issue bounties” (large amounts of funds) to researchers who discover security flaws in addition products. That’s an excellent thing.

Let’s hope Google doesn’t downplay the significance of this latest breach because controlling an individual’s phone number is risky. For instance, malicious actors can mimic the affected consumer and target others with phishing emails and other scams.

Scammers can tailor these scams to specific targets, and access to your personal information can aid hackers craft even more effective phishing messages.
