  1. The goal of a dusting attack is to link the victim’s wallet address to their real-world identity, potentially allowing the attacker to track the victim’s activities on the blockchain and compromise their anonymity.

  2. If a dusting attack is successful, the victim may be at risk of having their real-world identity linked to their wallet address, potentially exposing them to further attacks or privacy breaches.

  3. Dusting attacks can potentially work on both Type-1 and Type-2 deterministic wallets. In a Type-1 deterministic wallet, all of the addresses are derived from a single set of keys, which means that an attacker who compromise a single private key could potentially compromise all of the addresses in the wallet. In a Type-2 deterministic wallet, each address is generated using a separate set of keys, which provides increased security and anonymity.

  4. These features include “Dusting Defense,” which sends all incoming dust transactions to a separate address, and “Stain Protection,” which splits large transactions into smaller amounts to make it more difficult for an attacker to track the origin of the funds.

-Goal of a Dusting Attack:** The primary goal of a dusting attack is to break the privacy and anonymity of cryptocurrency users by linking multiple wallet addresses to identify the person or company behind them.

-Risks if Successful:** If a dusting attack is successful, the victim is at risk of being targeted by elaborate phishing attacks, cyber-extortion, or other forms of cybercrime, as the attackers can link wallet addresses to real-world identities.

-HD Wallets and Dusting Attacks:** Dusting attacks can affect both type-1 and type-2 Hierarchical Deterministic (HD) wallets. These wallets generate multiple addresses, but if dust is sent to multiple addresses and the dust is moved, it can link the addresses together.
