Hacker Develops Device To Surf The Internet Anonymously

A well-known hacker has developed a device that users can go online anonymously, without their actual location or IP address to give up. The ProxyGambit of Samy Kamkar is an "improvement and reincarnation" of the ProxyHam. The ProxyHam would be demonstrated at the Defcon hacking conference initially, but researcher Benjamin Caudill concluded his lecture for letting off unknown reasons.

Also destroyed it all prototypes of the ProxyHam and announced that the software and blueprints of the device would not be published. The ProxyHam was a device that consisted of a Raspberry Pi computer with Wi-Fi card and three antennas. An antenna connection made ​​with an open Wi-Fi network, for example at a Starbucks or library, and two antennas that sent the data to and from the user via a 900Mhz frequency. A user could be at a position of 4 kilometers.


Kamkar, which in recent months regularly with all kinds of hardware hacks in the news came out, decided to develop its own solution based on the idea of ProxyHam. The ProxyGambit however, leave more space between the user and the used Wi-Fi network. The device supports both a radio link as a mobile bridge to connect to a Wi-Fi network. In the case of the GSM network can bridge the thousands of kilometers away there. Is made ​​using a direct link, the distance 10 kilometers.

Like the ProxyHam assigns the IP address that is visible to the outside world to the Wi-Fi network that uses the ProxyGambit. To connect to the mobile bridge, which used 2G, can be used as Kamkar a prepaid SIM card, which can be obtained anonymously. "In both cases, your connection proxied by local Wi-Fi networks in the vicinity of the unit, making it difficult to determine your actual location, IP and identity," Kamkar says.

The hardware for the ProxyGambit consists of an Arduino Nano, Raspberry Pi, GSM Fona, USB hub, wifi adapter, Ubiquiti Nano Station and a Power over Ethernet injector. The cost of the parts amounts include 200 dollars. The software for the device, the hacker on GitHub placed while a Linux image via Dropbox is available for download. Kamkar warns that this is still a "proof of concept" goes and users for whom privacy and anonymity is important to do further research.
