My hardware wallet was hacked and transferred to a new wallet. Do I have to pay capital gains tax on this?

I usually withdraw all my bitcoin to a hardware wallet.

Out of nowhere, all my bitcoin got transferred out from my address to some random bitcoin address. I must have entered in my seed phrase on a fraudulent website or something.

Will the IRS see this and make me pay capital gains tax since transfer of bitcoin is a taxable event in the US?

Will the IRS think that new random bitcoin address is my address even though its not? If bitcoin were to move out of that address, would the IRS think that is my transaction?

I think the IRS would know my hardware wallet address is connected to me because I withdrew directly from the centralized KYC exchange to the address.

But would they assume the hacker's address is my new address?
