Position of all spawned prefabs being effected by MoveTowards (beginner question)

Just want to begin by saying that I am an extreme new comer to Unity and game programming in general. So this question is probably going to be extremely obvious, but it is giving me trouble.

So to try and explain my issue as best as possible. My game im working on is a really simple shoot-em up type game where I have prefabs(enemies) spawning from the right side moving left. A gameplay element I have is that the player can occasionally shoot some hacking shots that will give you control of the enemies and they are basically the usually upgrades you would have in a shoot-em up.

My issue comes up when I shoot the enemies with the hacking shot i want to use the MoveTowards to move them to a designated location (emptyobject) by the player. I have it working so that when i shoot a single enemy on screen it will move to place. However, if there are more than one one screen they all start to move to the designated location even if I have only shot one of the enemies.

I feel like there is some way to only manipulate the position of a single prefab at a time and not change all of them together.

Let me know if there is any other info you could use to help solve my issue.

Thanks!
