Matic withdrawal gone weird - need advice

Hi all,

I just made a withdrawal from an exchange to my ledger.

Instead of Matic I have received suspicious NFT Polygon1 $1000 USDC reward.

I contacted exchange support right away, but I’m wondering if my ledger has been compromised and I need to transfer rest of my funds to different place.

In case you are wondering my 24 phase can’t be compromised as it’s only written on the paper.

Been using ledger for some time but this is the first time I’m expecting such issues.

Thank you all Will add some more as I’m not sure if it’s already 500
