Pwnie Express drew a lot of attention earlier this year with its Pwn Plug, a stealthy, small computer loaded with network hacking tools disguised in an innocuous, white power brick that resembles an air freshener—albeit one with Ethernet and USB ports. Now, with funding from the Defense Advanced Research Projects Agency’s Cyber Fast Track program, the company has created an even stealthier tool for testing and cracking networks: one disguised as a power strip.

The Power Pwn, now available for preorder, looks and works like a surge-protecting power strip, with eight functional 120 volt outlets. But it is also a Linux-based computer loaded with hacking software, including high-gain WiFi and Bluetooth antennas as well as dual Ethernet ports. There's also an external 3G/GSM adapter that allows it to use cellular wireless networks. It can be preconfigured using a Web interface, and then casually swapped for the power strip on any computer on the network.

Once in place, an attacker/penetration tester can communicate with the device via text message, sending command-line input via SMS, and establish an SSH secure shell session. It can then detect and launch attacks on any detected wired or wireless network or Bluetooth device.
