How will hacker drones infect nearby computers?

According to leaked documents on WikiLeaks, Boeing subsidiary Insitu and malware firm Hacking Team show that the companies were discussing the possibility of a drone that could infect computers by flying by their Wi-Fi networks, hacking their way on and injecting malware.

While hacker drones are not yet known to exist, the value of wartime and spying applications make such a technology sure to appear in coming years.
