A well placed missile to the relatively thin armor at the aft of the ship can easily destroy the reactor, cutting power to the ship's point defenses rendering it helpless while you hack the remaining systems before using the backup generator to restore power.
While the ship has 2 reactors, only the large reactor is fueled. Another option is to eject junk materials towards the ship so that the turrets are distracted by your cloud of chaff, allowing you to park your ship in a blind spot on the hull, or move in closer for a better shot. The gatlings will not open fire until you close within ~600m, the missiles within ~300-400m, as such one strategy is to match speed and heading with the hauler and pick off the point defenses from a safe distance. The mining hauler is well armed, sporting 4 gatling turrets and 2 missile turrets 1 gatling and 1 missile on dorsal and ventral sides, plus a gatling on each side of the craft, with the ventral turrets also having clear line of fire across the front and rear of the ship.
