Mr. Robot didn't have to imagine a new device for last week's episode. The phone used to tap into a certain Dark Army's conversation is a product from Pwnie Express, a Boston-based startup focused on device threat detection. For Pwnie Express, the device called the Pwn Phone allows anyone to test for vulnerabilities within wired, wireless and Bluetooth networks. There are more than 100 open source testing tools built into an Android phone, which retails for 1300. Robot' just revealed its latest mind-bending twist, but this one feels a bit familiar Pwnie Express specializes in making its penetration testing equipment look like air fresheners, power strips, and for the case of the Pwn Phone, a regular cell phone.
