What Are Poison Attacks?
Address poisoning is a scam that exploits user behavior rather than directly hacking systems. Here's how it works:
- Impersonating Addresses: Scammers generate wallet addresses that closely resemble those you’ve recently interacted with.
- Sending Small Transactions: They send tiny amounts of cryptocurrency, often just fractions of a cent, to your wallet.
- Poisoning Transaction History: This transaction appears in your history, alongside legitimate transactions.
The aim is to trick you into copying and using the fake address for future transactions, leading to funds being sent to the scammer.
Poison Attacks on Solana
Solana, known for its speed and low transaction costs, has been a prime target for address poisoning. The low fees make it easy for attackers to send numerous small transactions without incurring significant costs.
When your Solana wallet is targeted:
- You may notice unfamiliar microtransactions in your history.
- These transactions often come from addresses mimicking those you’ve used.
While the Solana network itself remains secure, this scam relies on human error. Users who copy-paste wallet addresses from their transaction history without careful verification risk sending funds to an attacker.
How to Protect Yourself
To safeguard yourself from address poisoning when using VALR or any other platform, consider the following measures:
- Verify Entire Addresses: Always double-check the full recipient address before initiating a transaction. Avoid relying solely on the first and last few characters, as scammers often create addresses that mimic these segments.
- Use Wallet Address Book: VALR allows you to save and label trusted addresses. Utilize this feature to ensure you're sending funds to the correct recipients.
- Conduct Test Transactions: For significant transfers, send a small amount first to confirm the accuracy of the recipient's address. This step can help prevent substantial losses due to address errors.
- Stay Informed: Regularly update your knowledge about emerging scams and security practices.
By implementing these practices, you can significantly reduce the risk of falling victim to address poisoning scams on VALR, or any other cryptocurrency platform/wallet.
