Funds in GameStop wallet

I set up this chrome extension GameStop wallet when it was first released. And I somehow got logged out, until today when I re-entered my seed phrase. And now I see that I have an amount of Ethereum in this wallet. I'm pretty sure I didn't deposit this amount. Has anyone else had this happen? Is this a way to steal money if I transfer this to my exchange or my cold wallet?

Edit: and it says no activity under the activity tab. I would think it would say when this deposit was made at least
