has just published on the Google Security Blog. It highlights the lack of a feature in Samsung’s smartphones and tablets that could expose people to privacy and security attacks leading them to fall for fraud and scams.
In the blog post, Google explains that fraudsters or scamsters can use cell-site simulators, also known as False Base Stations (FBS) or Stingrays, which are radio devices, to create their own 4G and 5G networks. They can then customize those to make them appear as networks provided by well-established carriers.
At this point, mobile phones nearby might start connecting to these fake networks as they might not be able to differentiate between a fake and a real one. Once that happens, criminals force these devices to connect to a 2G network created by them.
Now, the 2G network lacks many crucial security measures that 4G and 5G networks offer. Leveraging the lack of those security features, criminals can send an SMS containing spam to those devices, which could lead their owners to fall for frauds and scams, as well as surveil them and intercept their communications.
To safeguard from these privacy and security attacks, Google asks people to turn off the 2G network on their Android devices. According to the company, Android has been offering people the option to turn off the 2G network since .
Unfortunately, Samsung’s smartphones and tablets don’t offer an option to turn off the 2G network, even though Android has been offering the feature for more than two years now. Samsung's devices provide only the network modes that you see in the screenshot below and none of them let you turn off the 2G network.
This exposes Galaxy phone and tablet owners to scams and fraud through the attacks mentioned above. We hope that Samsung is taking note of this and offers a software update to all Galaxy devices that adds the ability to turn off the 2G network.
