As previously mentioned, the success of an address poisoning attack relies on the user's inattention. Fraudsters use a well-calculated tactic by intentionally sending a small amount of cryptocurrency to a specific address in order to poison its history. When the user copies the address of the last transaction, assuming it to be their own, they unwittingly transfer their cryptocurrencies or NFTs to the deceptive address, enabling the attacker to pocket money fraudulently.
Address poisoning involves several well-defined steps. First, hackers search for active addresses using bots to scan the network. They target addresses that carry out frequent transactions, to maximize their chances of success.
Having identified these addresses, they use applications such as "Vanity" to generate addresses similar to those of the victims. The attackers are obviously aware that most of the time, cryptocurrency users simply check the first and last characters of their long and complex address to make sure it's really theirs. To fool the user, when creating the fraudulent address, the attackers will therefore use the same first and last characters, but they will change the middle part, which is often overlooked and forgotten.
While there is no way to prevent the receipt of cryptocurrencies from malicious individuals attempting to steal your funds, it is possible to implement methods to protect your assets against this type of attack.
To effectively protect yourself from address poisoning, it's essential to follow these security measures:
1) Fully check and double-check your address before taking any action from your wallet, to ensure its authenticity.
2) Avoid copying addresses from the history when transferring funds. Instead, write down or save the address in a secure place, or use alternative methods such as QR code scanning.
3) Perform a test transaction by sending a small amount of cryptocurrency before sending the full amount. This verifies that the user is receiving the cryptocurrency and that it is not being sent to a fraudulent address.
4) Using an address book, available on most cryptocurrency wallets, is also a good solution. This feature enables you to securely store and manage your addresses or those of your recipients, reducing the risk of copying a fraudulent address.
In conclusion, address poisoning, although relatively less dangerous than other types of attack, can nevertheless prove formidable. If you are reading this article, you are now familiar with this new type of attack. The use of blockchain and, by extension, decentralization, appeals to our responsibility and requires constant vigilance on our part. Transfers of cryptocurrencies or NFTs should, as far as possible, take place in a calm environment, far from stress and haste. To avoid this type of trap, always be focused, take the time to check addresses carefully and implement the rules of good practice, as set out above. These security measures may seem redundant, but they serve above all to protect our assets and prevent the risks associated with address poisoning and other threats.
Finally, the security of our portfolios depends, in part, on our commitment to these security measures, and to keeping abreast of the latest trends and techniques used by cybercriminals.
