There was this ship and it found another ship that was Russian, and it was infected with this Electricity that could think and the electricity built itself bodies.

An extraterrestrial AI infiltrated the computer system
Of a Russian freighter far out to sea. The hostile intelligence
Set about building itself an invasion force out of whatever machines or materials that were available, including the crew's body parts
And a group of salvage workers that later boarded the ship.
