Privacy advocates disappointed about the sudden and unexplained demise of the ProxyHam device for connecting to the Internet have reason to cheer up: there are two similarly low-cost boxes that do the same thing or even better.
The more impressive of the two is the ProxyGambit, a $235 device that allows people to access an Internet connection from anywhere in the world without revealing their true location or IP address. One-upping the ProxyHam, its radio link can offer a range of up to six miles, more than double the 2.5 miles of the ProxyHam. More significantly, it can use a reverse-tunneled GSM bridge that connects to the Internet and exits through a wireless network anywhere in the world, a capability that provides even greater range.
Its creator, serial hacker Samy Kamkar, wrote in a blog post:
A high speed (150Mbps+) link is available with direct line of sight from 10km+ away, or if further away, a 2G GSM connection produces a reverse TCP tunnel serializing a shell into the device accessible from anywhere in the world via the Internet or GSM. Either method proxies your connection through local wifi networks near the device, shielding and making it more difficult to determine your true location, IP and identity.
ProxyGambit is an improvement and reincarnation of ProxyHam, the promising device that was to debut at Defcon 2015, yet vanished with no source, documentation or reason for its “destruction”. ProxyHam “promised to mask your location online by putting you up to 2.5 miles away from your router”
