A simple drive with a CryptoPhone reveals fifteen new rogue sites, by Steve Ragan
Towards the end of July, ESD America, the makers of the ultra-secure CryptoPhone, said that their engineers and customers had discovered more than a dozen rogue cell towers (also known as interceptors or IMSI catchers) around the U.S.
New information shows that the discovered towers might only represent a small fraction of the whole, and what’s been discovered doesn’t account for the mobile base stations that are only active on a limited basis.
Interceptors are a huge risk if used by a malicious actor. That’s because once a device connects to them, the interceptor’s operator can perform a number of tasks, including eavesdrop on calls or text messages, or in some cases push data (spyware for example) to the device. This is why they’re only supposed to be used by law enforcement or the government.
However, that doesn’t mean that the government or law enforcement haven’t found themselves in the hot seat for abusing an interceptor’s functionality. The potential for abuse and wide availability of the technology, including home-grown versions that work just as well as their commercial counterparts, means that the existence of unknown interceptors are a major concern.
