Leaking shock?

I’ve noticed this twice now with my car. The first time I had zero break fluid in the entire car but when I pushed it around the shop I noticed a very small leak. It didn’t have much of a smell to it and not much color. Well today my dad tells me that there is a leak in the same spot. He thought it was the brakes but pulled the wheel off and could not find any brake fluid leak but he said it looked like it was running off the lower control arm. These are super cheap shocks I ordered off rock auto but I’m a little surprised they would be leaking after a couple years on the car.
