A crypto dusting attack is a type of cyber attack that targets cryptocurrency users. In this attack, a small amount of cryptocurrency, known as "dust," is sent to the victim's wallet. This dust is often in the form of a fraction of a cryptocurrency unit and is too small to be of any value on its own.

The purpose of a crypto dusting attack is to track the victim's transactions and gain access to their personal information. By sending dust to the victim's wallet, the attacker can track the movements of the cryptocurrency and potentially link the wallet to the victim's identity.

Crypto dusting attacks are often used in combination with other forms of social engineering or phishing attacks, in which the attacker tries to trick the victim into revealing sensitive information or providing access to their accounts.

To protect against crypto dusting attacks, cryptocurrency users should avoid clicking on suspicious links or downloading unknown software. They should also regularly check their transaction history and monitor their wallet for any unusual activity. Additionally, using privacy-focused cryptocurrencies or wallets can help to reduce the risk of tracking and exposure to dusting attacks.
