Normal traffic may be tracked, government agencies love slurping on vast levels of information, and even networks like VPNs can only protect you up to now. For activists, journalists, political dissidents and — yes — offenders, this could mean their actions are open to spying eyes.

Expected to be unveiled in the Def Con hacker convention in Las Vegas next month, the research worker has created a miniature apparatus made to muffle Internet traffic and also make the source more difficult to monitor by law enforcement or government agencies, Proxyham.

Proxyham is basically a hardware proxy that allows users to connect to a public Wifi network over low frequency radio stations. As described by Motherboard, Proxyham is comprised of three antennas and a Raspberry Pi computer.

One antenna connects to a public Wifi network — such as a bookstore or Starbucks — while the sign is transmitted by the other two at 900MHz. A 900MHz antenna must be plugged into the user’s ethernet interface.
