Received 0.05 RENDER from unknown sender, help me understand this please

I received 0.05 Render in my sol wallet, solfire notified me. I do hold lot of render in my wallet and have sol staked etc

Can this be a scam? Or trying to hack me?

The token sent is legit RENDER token with contact address of rndrizKT3MK1iimdxRdWabcF7Zg7AR5T4nud4EkHBof

The sender is C3E5bGdEZ9SzAbN7Ef45czDGbkDdGBGBcXtXV3cWuQgz and when i look up that wallet is sending RENDER to so many wallets… what is it?
