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Also destroyed it all prototypes of the ProxyHam and announced that the software and blueprints of the device would not be published.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.

ProxyGambit

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.

Anonymous Making Wifi Device Also Easily Yourself

During the upcoming Def Con hacking conference in Las Vegas would be a researcher showing how a tool can be made ​​anonymously to the Internet via Wi-Fi networks that are located kilometers away. Via the ProxyHam , such as the tool is called, must be prevented from users on the basis of their IP-address can be detected.

The IP address in question, namely, always leads to the Wi-Fi network is kilometers away from the user. As the user makes via the 900Mhz frequency with ProxyHam connection, it would be difficult to trace. The solution was, according to researcher Benjamin Caudill especially suitable for whistleblowers and activists. Caudill during his presentation would also make the software and blueprints public so that everyone could make the device itself.

Last week it was revealed that Caudill has canceled his lecture and the prototypes of the device are destroyed . One reason would not give the investigator. Security researcher Robert Graham now has a description how to put online for less than 300 euros a ProxyHam-like device can be made ​​and how the device itself to other solutions relationship. Also on hackaday has been released a short explanation to make their own ProxyHam. Whatever the reason for Caudill had to cancel his lecture is still unknown.

Anonymous Surfing Via Wi-Fi Network In Kilometers

An IP address usually leads to the physical location of an Internet user, but a security researcher has developed a hardware-based solution that makes it possible to surf the Internet anonymously via Wi-Fi networks that are located on kilometers away.

Even if the IP address is traced, the actual location and identity of the user is protected. The solution devised Benjamin Caudill , founder of Rhino Security Labs, the ProxyHam. Anonymity on the Internet is as Caudill under fire, especially for whistleblowers. Although Tor provides some anonymity, there is still a fundamental vulnerability present. Namely, the direct relationship between the IP address and a physical location.

"If your real IP address is detected, the game is over, a big threat if the enemy manages the infrastructure," he tells the notice of the ProxyHam. This device will present at the upcoming Caudill Defcon conference and Internet users must provide more anonymity. The ProxyHam acts as a hardware proxy traffic from the user sends to a Wi-Fi network that is located on kilometers away, says the researcher opposite Vice Magazine.

Hardware

The device consists of a Raspberry Pi computer with Wi-Fi card and three antennas. An antenna that connects to an open Wi-Fi network, for example at a Starbucks or library, and two antennas that send the data to and from the user via a 900Mhz frequency. A user can be located at a position of 4 kilometers. To make the connection ProxyHam the user must connect a 900Mhz antenna on the Ethernet port. An attacker would detect the user will find that only the IP address of the ProxyHam.

The signal emitted by the ProxyHam has such a low frequency that it is difficult to follow. In addition there are in this frequency range of other devices, such as cordless phones, baby monitors and walkie-talkies. Caudill is now working on new features, including an option to destroy the proxy to let themselves be messed with it. The researcher tries to hide the proxy in certain objects like a book. Because of this disguise it can take years before the device according to Caudill is found in a library.
