As the world of cryptocurrencies grows rapidly with innovation, the increasing security threats in this area cannot be ignored. A new type of attack, known as "address poisoning," has emerged, posing a serious threat to crypto users. In this article, we will explore what address poisoning is, how it works, and how you can protect yourself from such attacks.
What is Address Poisoning?
Address poisoning is a method of attack that involves tricking users by imitating cryptocurrency wallet addresses. The basic principle of the attack is for hackers to analyze the transactions of targeted wallets and create addresses very similar to those the wallets normally send money to, then send small amounts of money to these addresses. Victims, mistaking these addresses for familiar ones, may mistakenly make large transfers of money.
Recent Cases and Losses
In the past four months, 21 Safe Wallet users have lost 5 million dollars due to such attacks. These cases highlight the serious consequences that address poisoning can have. A critical role in these attacks is played by the Create2 function in Solidity. Security firm Slowmist reported another group of hackers using the Create2 function to steal 3 million dollars from 11 victims.
The Role of the Create2 Function
Create2 is a function in Solidity, the programming language of Ethereum. This function allows for the pre-computation of contract addresses. However, this feature can be exploited by malicious individuals. Hackers can use this function to create addresses similar to existing ones and convince users to send money to these addresses.
Ways to Protect Yourself
As a crypto user, here are ways to protect yourself from such attacks:
- Careful Address Verification: Always check the sending address carefully before each transaction.
- Use Secure Wallets: Choose reliable wallet providers.
- Stay Alert to Suspicious Transactions: Be cautious of unexpected small transfers.
With the rapid growth of the crypto sector, security threats are also increasing. New types of attacks like address poisoning require users to be careful and informed. Always be vigilant and conduct your transactions safely.
