Scam Sniffer Warns of Increased Risk of Transaction Simulation Spoofing Attacks
Scam Sniffer, a leading digital security firm, has issued a warning about the heightened risk of transaction simulation spoofing attacks in Web3 wallets. These malicious attacks, which involve tricking users into approving malicious transactions by simulating or mimicking legitimate transaction requests within the wallet interface, have been on the rise.
In late 2024, Scam Sniffer exposed a fraudulent scheme using fake influencers and malicious Telegram bots to steal crypto assets. This incident underscores the importance of the new recommendations issued by Scam Sniffer.
The recommendations aim to protect users from potential asset drain by hackers. If a user signs a transaction, hackers can potentially drain their wallet. To prevent this, Scam Sniffer experts advise the following:
- Verify transaction details carefully before approving, especially the recipient address and amount, to avoid blindly approving spoofed transactions.
- Use wallets with strong anti-phishing and transaction alert features that clearly show actual transaction data separate from any simulation or preview.
- Avoid installing unknown or untrusted browser extensions or wallet add-ons, as these can inject malicious code to spoof transaction prompts.
- Regularly update wallet software and browser extensions to patch vulnerabilities that attackers might exploit for transaction simulation.
- Leverage security tools like transaction simulators outside the wallet to independently verify transactions before signing.
- Employ hardware wallets where possible, since physical confirmation on a hardware device makes spoofing significantly harder.
In addition to these recommendations, Scam Sniffer suggests that Web3 wallet developers update the frequency of transaction simulation to match the actual block creation time. This adjustment is aimed at reducing the time delay between transaction simulation and execution, which could potentially allow attackers to manipulate contract states on-chain on January 10, 2025.
Scam Sniffer experts also recommend forcing a fresh simulation result before critical operations. This measure is intended to ensure that users are presented with the most accurate and up-to-date transaction information before they approve any transactions.
By following these recommendations, users and developers can significantly reduce the risk of falling victim to transaction simulation spoofing attacks. As always, it's crucial to remain vigilant and proactive in protecting digital assets.

Given the context of the text, here are the two sentences that contain all the given words:
- To protect users from potential asset drain by hackers, Scam Sniffer experts advise using wallets with strong anti-phishing and transaction alert features, which can help in identifying Ethereum transactions more securely.
- By leveraging security tools like transaction simulators outside the wallet, users can independently verify Ethereum transactions before signing, providing an additional layer of cybersecurity.
