Dust Attack?

I just noticed that someone sent 333 sats to my hardware wallet address. It’s not anyone I know and I didn’t see it coming. When I review the full transaction details I see that they sent 333 sats to about 1700 different address or outputs.

I’ve heard I should label that transaction/utxo and forget about it and never spend it/send it. Anything else I should consider or do about this? What’s the risk of being “dusted”? Just privacy and them associating that utxo/address to my other address that I hold?

I feel like this is being done by chain analysis companies. But maybe others have thoughts?

Thanks!
