A dusting attack is a relatively new type of malicious crypto activity. Unfortunately, it has been gaining momentum for the past 12 months. So, what is it?
Before we examine the specific aspects, we need to define ‘Bitcoin dust.’ Within the crypto universe, Bitcoin dust refers to a microscopic amount of Bitcoin held within a wallet or address. Officially, the monetary value of Bitcoin dust is lower than the minimum limit of a valid transaction.
The value is so tiny that it is even lower than the amount of the Bitcoin network fee. Therefore, it’s basically impossible to process a BTC transaction. For all practical purposes, Bitcoin dust is worthless. It becomes nothing more than a nuisance inside a person’s wallet or address until more Bitcoin is added and takes it over the useful threshold.
How Bitcoin Dust is Used in a Dusting Attack
Bitcoin dust is needed to initiate a dusting attack. Contrary to popular belief, a dusting attack is not a type of monetary theft. Many people believe that it involves the theft of Bitcoin. This is not true.
Instead, a dusting attack is a theft of identity. The perpetrator is attempting to steal your identity, not your Bitcoin.
Misconception the Bitcoin is Anonymous
In the early days of Bitcoin, one of the common misconceptions was that all transactions were completely anonymous. There was a belief that the Bitcoin blockchain network provided users with the ability to conduct private BTC transactions without the fear of being identified. Today, we know this isn’t true.
Admittedly, it is difficult to find the identity behind each address or transaction. However, it’s not impossible because all transactions are visible to the public. The public visibility of all transactions is the reason why dusting attacks can be perpetrated.
The best way to avoid a dusting attack is to only initiate peer-to-peer transactions because these types of transactions completely eliminate the need for a middleman. Dusting attacks are most prevalent when crypto users transact funds between a personal wallet and an exchange account.
These days, the vast majority of crypto trading exchanges require KYC verification, which results in the collection of personal information. Consequently, users are vulnerable to compromising their anonymity whenever they transfer crypto funds between their personal wallets and exchange account. This is the target for a dusting attack.
What a Dusting Attack Does
Now that we have established the fact that Bitcoin transactions are not anonymous, let’s describe a typical dusting attack. The goal of the hacker is to capture the identity of a BTC user. In order to accomplish this objective, the hacker (or scammer) will send out tiny amounts of Bitcoin to the personal wallet of the potential victim.
The next step is to track the activity of the wallet. By tracking the activity, the hacker can identify wallet owners through collective analysis.
At this point, you’re probably thinking that most wallet owners would recognize the tiny amounts of BTC added to their accounts and become suspicious of the transaction. Unfortunately, scammers have discovered that the vast majority of wallet owners typically don’t monitor their account activity on a regular basis.
In fact, Bitcoin dust is so tiny and insignificant, that these transactions often remain unrecognized for long periods of time. Of course, this is precisely what the hackers are trying to accomplish.
The ultimate objective of the scammers is to link addresses to the wallet owners. Upon successful identification, the scammers could use this knowledge against their targets in a phishing attack or some type of cyber extortion
As Bitcoin activity has increased during the past several months, dusting attacks have been on the rise. The crypto community can do its part to mitigate these attacks by remaining vigilant and verifying each transaction in the owner’s wallet.
Several wallet companies are attempting to prevent dusting attacks by implementing real-time alerts and notifying wallet owners of suspicious activity. This is definitely a step in the right direction.
