[There have been many comments to this story from people who are assuming that these 'towers' are physical installations. There's no reason to assume this is the case: it's far likelier that they are mobile installations of the kind used not only by law enforcement and government agencies, but also by scammers and other criminals.

Seventeen mysterious cellphone towers have been found in America which look like ordinary towers, and can only be identified by a heavily customized handset built for Android security – but have a much more malicious purpose, according to Popular Science.
The fake ‘towers’ – computers which wirelessly attack cellphones via the “baseband” chips built to allow them to communicate with their networks, can eavesdrop and even install spyware, ESD claims. They are a known technology - but the surprise is that they are in active use.
The towers were found by users of the CryptoPhone 500, one of several ultra-secure handsets that have come to market in the last couple of years, after an executive noticed his handset was “leaking” data regularly.
Its American manufacturer boasts that the handset has a “hardened” version of Android which removes 468 vulnerabilities from the OS.
Android Security: Towers in casinos
Despite its secure OS, Les Goldsmith of the handset’s US manufacturer ESD found that his personal Android security handset’s firewall showed signs of attack “80 to 90” times per hour.
The leaks were traced to the mysterious towers. Despite having some of the functions of normal cellphone towers, Goldsmith says their function is rather different. He describes them as “interceptors” and says that various models can eavesdrop and even push spyware to devices. Normal cellphones cannot detect them – only specialized hardware such as ESD’s Android security handsets.
Origin of towers ‘unknown’
“Interceptor use in the U.S. is much higher than people had anticipated,” Goldsmith says. “One of our customers took a road trip from Florida to North Carolina and he found eight different interceptors on that trip. We even found one at South Point Casino in Las Vegas.”
Their existence can only be seen on specialized devices, such as the custom Android security OS used by Cryptophone, which includes various security features – including “baseband attack detection.”
The handset, based on a Samsung Galaxy SIII, is described as offering, a “Hardened Android operating system” offering extra security. “Baseband firewall protects against over-the-air attacks with constant monitoring of baseband processor activity, baseband attack detection, and automated initiation of countermeasures”, claims the site.
“What we find suspicious is that a lot of these interceptors are right on top of U.S. military bases.” says Goldsmith. “Whose interceptor is it? Who are they, that’s listening to calls around military bases? The point is: we don’t really know whose they are.”
each year when they announce "the next big thing is here", looks like they are neglecting to inform us of the other big thing already here. we get all giddy the new shiny thing oooooo, but as we know everything that they come up with to protect us something comes with it to counter it, I think it's all industry driven if that next big thing was all that then we would not need security or all the bells a whistles that make us feel so warm and cuddly and security like Norton et al would be out of business.
we hear of companies hiring those hackers to tell them what they need to guard against but by doing that they discover what can be done to invade your space, all about the Benjamin's.
