Winter Creeper (Euonymus fortunei)

I have that all over my property too!! I thought it was poison ivy too but i'm 99%sure it is winter creeper

Did it start out with lighter leaves like in this photo? and then it eventually all turned dark green?

Yeah Im pretty sure it is Winter Creeper after doing some more research. We have a ton of it growing up a lot of trees on our property.

Definitely Euonymus.
Just for future reference do take a minute to look at this excellent link on poison ivy.

It's winter creeper and it gives me the willies to even think about it. I thought I had written a treatise on it but I don't see it in the comments. This is one nasty vine. If you clip it or pull it to rid yourself of it, be sure to get every single root. I didn't know that and ended up with giant shrubs taking over. Took me forever to get rid of the shrubs. And then it took me forever to get rid of all of the roots. I'm still a little paranoid that I might see it return.

Found my pictures. They're in the Plants Database listed as:
Purple Wintercreeper Euonymus (Euonymus fortunei 'Coloratus')
The pictures show how it grew into shrubs and also the nasty roots.

Thanks Flower Child. Yeah I have it everywhere. Going to take some time for sure!
