Discover how to avoid Web3 scams and protect your crypto assets. A comprehensive guide on the 4 common fraud methods, 7 essential precautions, and the steps to secure your Web3 wallet. Expert tips to prevent blockchain scams on Gate.
Cryptocurrency Scam Method (1): Encouraging Clicks on Suspicious Links and Authorizing Wallets
Web3 wallets serve as our gateway to the decentralized world, but they are constantly targeted by malicious actors. These fraudsters use bait such as mining, airdrops, or high-yield activities to entice users to click on unknown links and authorize their wallets on malicious sites, or to obtain their recovery phrases and private keys, resulting in asset loss. Due to the anonymity and decentralization of digital assets, recovering stolen funds is often difficult. Therefore, staying vigilant is essential.
Common methods of encouraging clicks include three main approaches:
- High-yield activities: Fraudsters promise exceptional gains through fake mining projects or fictitious airdrops, prompting users to open suspicious links and authorize their wallets.
- Impersonation of official entities: Scammers pose as official representatives of legitimate platforms to gain users' trust and obtain wallet authorization.
- Sending suspicious links: Unsolicited links or activities are sent directly to wallet addresses, encouraging users to authorize their Web3 wallets without prior verification.
Cryptocurrency Scam Method (2): Malicious Modification of Permissions
This scam often occurs during recharge processes via the TRC blockchain. Fraudsters exploit the psychology of "taking advantage of a good deal" by offering gift cards, fuel cards, or other products at abnormally low prices. They may also use SMS verification platforms to perform recharges. When users use the provided links to recharge, scammers activate malicious code that modifies permissions, obtaining the signature of the password and gaining full control of the wallet address.
Scammers typically carry out this fraud in two steps:
- First step: Through "lures" and various manipulation methods, they induce users to click on third-party links. From the recharge interface, they redirect to the wallet and use malicious code to automatically fill in the token contract address (Token).
- Second step: During the transfer process, warnings about permission modifications and associated risks appear. If the user proceeds, it results in malicious permission changes. On the next transfer attempt, an error message appears, but in reality, the user has already lost control of the address.
Cryptocurrency Scam Method (3): Using Similar Addresses to Deceive Users
Scammers generate addresses that are extremely similar to legitimate ones using address generators. This "spoofing" technique aims to deceive users when copying receive addresses. By creating addresses with the same first and last characters as the legitimate address, scammers exploit the common habit of users only checking the beginning and end of an address. This negligence can lead to funds being sent to the fraudulent address, resulting in irreversible asset loss.
Cryptocurrency Scam Method (4): Encouraging Disclosure of the Recovery Phrase or Private Key
Fraudsters employ various tactics to obtain sensitive wallet information. They may ask users to share their screens under the pretext of helping with investments, offer to buy or sell goods at low prices, or negotiate cryptocurrencies privately. Under these pretenses, they guide users to create a wallet and, through psychological manipulation, lead them to reveal their recovery phrase or private key. Once obtained, scammers gain full access to the wallet, leading to complete asset theft.
Precaution Against Scams 1: Project Verification
It is crucial to thoroughly understand the context of any project before engaging. Take the time to research the team behind it, their roadmap, and reputation in the community. If you encounter suspicious or unfamiliar activity, the first step is to contact the official customer service for confirmation. Never rely solely on unverified sources, as scammers often create fake websites and social media accounts imitating legitimate projects.
Precaution Against Scams 2: Address Confirmation
Never copy an unknown blockchain address to make a transfer without careful verification. Before withdrawing or transferring, meticulously check the address from start to finish, character by character. Ensure the address is correct before proceeding. It is recommended to perform a small test transfer first to verify the address. If any anomaly is detected, stop immediately and do not continue with the transaction.
Precaution Against Scams 3: Regular Wallet and Private Key Security Checks
Never click on suspicious links or participate in unsolicited airdrop activities received in your wallet. It is vital to regularly check if your Web3 wallet has authorized unknown sites and revoke permissions immediately if necessary. Many malicious sites obtain excessive permissions that allow them to spend your tokens without your explicit consent.
On hardware, avoid using internet-connected devices to back up or transmit your private keys. Never take screenshots or photos of your private keys, as these files can be compromised by malware or hackers. Devices connected to the internet always pose a risk of data leakage.
Precaution Against Scams 4: Physical Backup
Never disclose your private key, password, or recovery phrase to anyone, regardless of circumstances. No legitimate customer service will ever ask for this information. When possible, use physical media to back up these critical data. The safest method is to write your recovery phrase on paper and store it in a safe place like a safe deposit box. You can also use dedicated offline storage devices that are never connected to the internet, eliminating remote hacking risks.
Precaution Against Scams 5: Distrust of Unknown Links
Never click on unknown links, and do not connect your Web3 wallet to third-party applications with unknown risks. Malicious links can install spyware or Trojans on your device, or redirect you to phishing sites imitating legitimate platforms. Even if a link appears to come from a trusted source, always verify the full URL and look for signs of impersonation, such as subtle misspellings in the domain name.
Precaution Against Scams 6: Caution with Third-Party Applications
Never import your private key into unknown third-party websites. Do not download or use wallet apps from unverified sources provided by third parties. Always download applications only from official app stores or official project websites. If abnormal behavior occurs on your device, such as unusual slowness, frequent pop-ups, or excessive battery consumption, perform a full antivirus scan to detect potential Trojans or malware.
Precaution Against Scams 7: Vigilance Against Suspicious Websites
Never click on links to websites promoting gift cards, fuel cards, or recharge cards at abnormally low prices found online. Do not participate in recharges on these sites, especially those offering redirection services for recharging. Once you click a suspicious link and make a transfer, it is highly likely that your address permissions are maliciously altered, leading to financial losses. Legitimate recharge services only require you to transfer to the provided receive address, without redirection or additional permissions.
What to Do in Case of Cryptocurrency Scam? 3 Steps to Calmly Manage the Situation
Management Step 1: Transfer Remaining Assets
If you discover your wallet has been compromised, act immediately to transfer all remaining assets to a secure address. Time is critical, as scammers can empty your wallet at any moment. Create a new wallet on a clean, secure device, and transfer all unexploited funds there. Remember to verify all tokens and digital assets you hold, not just major cryptocurrencies.
Management Step 2: Delete the Compromised Wallet
After securing your remaining assets, immediately delete the compromised wallet. If you need to continue using wallet services, create a new wallet with a new recovery phrase. Never reuse a compromised wallet, even if you believe the issue is resolved.
To delete the wallet: On the Web3 wallet homepage, click the profile icon at the top left, then "Wallet Management". Click the wallet management icon at the top right and select "Edit Wallet". Click the red minus icon next to the relevant wallet, then confirm deletion.
Management Step 3: Proper Handling of Wallet Recovery Phrase and Private Key
It is absolutely vital to securely back up your wallet's recovery phrase and private key. Never take screenshots of your recovery phrase, as internet-connected devices always risk data leaks. The recommended method is to write down your recovery phrase manually and store it safely, out of sight and in a secure location.
Additionally, never authorize unknown third-party project software to access your wallet to prevent data leaks that could lead to asset loss. Remember, in the world of cryptocurrencies, you are your own bank, and your asset security fully depends on your personal security practices.
