79. What is a Dusting Attack in cryptocurrencies? How to protect against it?

In the world of cryptocurrencies, which is developing at a rapid pace, new security threats emerge regularly. One such phenomenon is the dusting attack, which is a subtle but potentially dangerous breach of the privacy and security of cryptocurrency holders.

In today’s lesson, we’ll have a closer look at what a dusting attack is, how it works, and what precautions you can take to protect yourself against it. We invite you to read on!

Crypto dusting – definition

This type of attack is a relatively new tactic used by cybercriminals. It aims to violate the anonymity and privacy of cryptocurrency users.

The core of this strategy is the so-called “crypto dust”. Dust is defined as small amounts of cryptocurrencies sent to the addresses of many wallets. We ask ourselves: Why are such small amounts being sent? Unfortunately, the intentions are not benevolent. It is a well-calculated manoeuvre to steal the user’s identity or carry out other illegal activities.

By sending micropayments to different addresses, the attacker also tries to find out which of these addresses are controlled by a single user. Once they have this knowledge, they can use more advanced tracking techniques, such as analysing transactions to learn about a particular user’s financial history.

Although the micropayments sent in a dusting attack are usually small, the consequences can be serious. Firstly, it can violate the privacy of wallet holders and make it easier for attackers to track their financial activities. Secondly, it can open the door to other forms of attack, such as phishing attempts.

How does a dusting attack work?

As we have already mentioned, “dust” is a small amount of a given cryptocurrency. Using BTC as an example, these are transactions equal to 546 satoshi (0.00000546 BTC).

In this type of attack, cybercriminals distribute cryptocurrency dust to countless wallet addresses. Each such transaction, regardless of its size, is recorded on the blockchain. Consequently, it can be viewed by anyone.

Once such a transaction has been carried out, the attackers observe the user who has received the dust and wait for their movement. If the recipient of a particular micropayment spends the dust unknowingly, the attackers already know which wallets are connected, ultimately leading to a breach of privacy.

This type of attack emerged in late 2018. It happened when users of the Samourai wallet were warned of potential Dusting. Since then, even major platforms have become targets of such attacks.

How do you protect yourself from these types of attacks?

In the face of increasingly common incidents of dusting attacks, it is hugely important for holders of cryptocurrencies to employ defensive strategies to secure their identities and digital assets.

Below are some simple steps that cryptocurrency users can take to minimize the risks associated with crypto dusting attacks:

Regular monitoring. Actively track your transactions by checking them regularly. Any unplanned microtransactions should arouse healthy suspicion.

Step away from the interaction. If you notice dust in your wallet, it is better not to move it. Interacting with it may provide attackers with the information they are looking for.

Take advantage of advanced wallets. HD (Hierarchical Deterministic) wallets, generating a unique address for each transaction, provide an extra layer of protection against potential tracking.

Convert dust. Some platforms offer services that allow you to convert cryptographic dust into native tokens, enabling you to use these small amounts effectively without compromising security.

Be alert to unsolicited messages. Treat any unexpected messages related to your cryptocurrency funds with caution, especially if they ask for personal information or access to your wallet. Verify such communications before taking any action.

Adopting these proactive measures can effectively help you secure your cryptocurrency holdings and preserve your privacy in the face of potential threats from dust attacks.


The dusting attack is another challenge for cryptocurrency holders. Understanding how this type of attack works and taking appropriate precautions can help protect privacy and financial security.

As cryptocurrency technologies evolve, so do the threats, and informed users are a key element in creating a safe space for digital assets.
