Hi. I received a few transactions on my wallet with a very small amount of cryptocurrencies, I don't know what to do with them, can I hold them? Someone trying to attack my wallet? What do you think ?
It looks like a dusting attack.This is a fairly common type of malicious activity which hackers and scammers try to break the privacy of Bitcoin and other cryptocurrency users by sending small amounts of coins to their wallets. Later, wallet transaction activity is tracked by hackers who perform combined analysis of different addresses to de-anonymize the person or company with each wallet. If successful, attackers can use this knowledge against their targets, either through advanced phishing attacks or cyber-extortion threats. So it's best to set up and start using a new wallet.
It looks 100% like dusting attack. I will explain to you what i sdusting attack really quick: What at first seems like a small, unexpected spray of crumbs is actually an annoying scam that undermines your anonymity and uses your identity against you.
The attacker sends a very small fraction of BTC to potential victims wallets, which can be marked as dust, respectively. crumb. The amount is so tiny that many wallet owners overlook or ignore it. We can say that at the time of acceptance of these crumbs, the wallet was "dusty" - hence Dusting Attack (dust).
You're probably thinking right now, but what's the problem? What makes Dusting Attack so dangerous?
As you probably know, bitcoin network transactions are publicly traceable. Anyone can check the status of your wallet and go through your transactions. However, they will not know that this is your wallet, because information about the owners is of course no longer publicly available.
However, if someone assigned your wallet address to your person, they would know all your transactions and the status of your wallet and could practically track you, even if you created a new wallet and transferred it there.
In this case, the attacker does not pursue the goal of giving you a few trivial crumbs, but wants to create a directory that tracks all the addresses managed by your wallet. We won't go into details, but your wallet generates multiple addresses when you pay somewhere and inserts balance coins in them. This happens whenever you pay or send a transaction somewhere, unless you send the exact amount of your wallet, which is rarely the case.
