The drone can reach a height of 22,000 feet Richard Perkins and Mike Tassey both worked in information technology in the U.S. Air Force before decamping to various cybersecurity consulting roles in and around the Department of Defense. But throughout their careers they’ve always considered themselves hackers at heart, which is why they spent the past two years developing the ultimate mobile hacking device: a drone aircraft that can discreetly break into Wi-Fi networks, emit jamming signals, and even pose as a cellphone tower to intercept communications from the ground.Perkins and Tassey shared an interest in remotely piloted aircraft, and with their professional backgrounds, they naturally began dreaming up surveillance applications. Their Wireless Aerial Surveillance Platform, known as Vespid (the Latin word for “wasp,” a play on the acronym), is a modified surplus FQM-117B Army target drone. In place of the aircraft’s original radio equipment, Perkins and Tassey substituted compact components including a high-powered radio antenna for intercepting and broadcasting signals, a 32-gigabyte USB drive to store swiped data, and a 4G USB dongle to keep Vespid connected to a server on the ground.Two lithium-polymer batteries power the 76-inch-long drone, which can remain aloft for more than half an hour.Although the aircraft has impressive spying abilities, Perkins and Tassey say that they don’t have designs on other people’s data. They showed Vespid at a security conference in Las Vegas in August to make a point: If they could construct a spy drone from legal, off-the-shelf components for a few thousand dollars, then despite its complexity, others could do the same—including those with nefarious motives.Yet Vespid could have some helpful applications. As easily as it can steal data, it can also provide Wi-Fi connectivity and cellphone service in areas affected by natural disasters or hunt for cell signals in devastated areas, turning ordinary cellphones into search-and-rescue beacons.
