Bugging
Bugging weapons are primarily designed to attach a tracking device to a starship on a successful hit, and thus don’t typically deal damage. The tracking device allows the starship that made the attack to trace the bugged starship even when it engages a cloaking device. The tracking device stops functioning once the bugged vessel enters the Drift. Otherwise, personnel must remove the device from the exterior of the starship and deactivate it (requiring a successful Engineering check with a DC equal to 10 + 1-1/2 × the tier of the attacking ship) in order to prevent being tracked. A bugged ship automatically knows it has been bugged.
