You suddenly got 0.000001 BTC Satoshi in your bitcoin wallet. But you know you haven't sent the funds that you received to your wallet. Or youre not supposed to get this fund from anywhere. This means you are under a dusting attack. But, you do not know what is dusting attack. For which maybe you did not give importance to getting that fund. Its dangerous. So know what dusting attack is. And save yourself from danger.
A very small amount of funds in cryptocurrency is called dust. You may find dust while trading, that some amount of funds from the orders you place to trade remain in the wallet. This very small amount of funds is called dust balance. Ex- 0.00000012 BTC etc.
Hackers send very small amounts of tokens or coins to a wallets for dusting attacks. And that keeps the wallet in trucking. Because when a token or coin is sent from one's wallet to someone's address, it becomes very easy to track it. By that tracking, hackers find out the identity of the targeted wallet. When the hacker is able to find out the identity of the person in the targeted wallet, the hacker puts the person in danger with a phishing attack or cyber thread.
If you're using an exchange wallet, there's nothing to warried about. Just keep your account security hard. In this case 2FA can be used. And update your passwords occasionally. And if you are using a personal wallet and noticed anything about it then you need to create a new address for every transaction.
