Dusting attacks’ goal is to deanonymize users. By sending small amounts of various wallets, attackers could break the privacy of users.
If successful, the users would be identified and attackers could blackmail users.
It works on all wallets.
Dusting alert and Do Not Spend features were added to Samurai Wallets to prevent Dusting.

To identity and analyze blockchain TXs and de-anonymize user.
As soon as dust TXs that are sent to users start moving, the users ID can be de-anonymized to attackers.
Dusting attacks work on all wallet types. just make sure not to move those funds. some wallets like Samourai Wallet allow those unknown dust-amounts to be frozen. Again: Do not reuse wallet addresses.
It can freeze unknown inbound dusts from being transacted later.
