Rogue cell phone towers can track your phone and intercept your calls, and it’s only a matter of time before they’re as ubiquitous as GPS trackers. But at least now there’s a way to spot them.
A firewall developed by the German firm GSMK for its secure CryptoPhone lets people know when a rogue cell tower is connecting to their phone. It’s the first system available that can do this, though it’s currently only available for enterprise customers using Android phones.
GSMK’s CryptoPhone 500, a high-end phone that costs more than $3,000 and combines a Samsung Galaxy S3 handset with the CryptoPhone operating system, offers strong end-to-end encryption along with a specially hardened Android operating system that offers more security than other Android phones and the patented baseband firewall that can alert customers when a rogue tower has connected to their phone or turned off the mobile network’s standard encryption.
