Hacker Drone.
Slow and vulnerable to Point Defence weapons.
Attaches to enemy unshielded ship and temporarily destabilizes chosen module:
FSD - disallows to low/highwake for duration of hacking.
Thrusters - periodically destabilize them, causing enemy ship to lose course (like if his ship went FAoff suddenly).
Power Distributor - constantly change PD energy management.
Sensors - screw up enemy sensors completely, by showing multiple flashing objects on his radar.
"Vampire" - drone drains additional 2 Mw from target ship energy grid, which can end pretty bad for enemy.
