The promise of blockchain technology—“be your own bank”—comes with great responsibility. While decentralization empowers users to control their digital assets, it also makes crypto wallets prime targets for cybercriminals. According to blockchain security firm CertiK, 223 hacking incidents occurred in the first quarter of 2024 alone, resulting in over $502 million in stolen digital assets. At the heart of many of these attacks are two increasingly sophisticated scams: ice phishing and address poisoning.
These threats exploit human behavior, not just technical vulnerabilities. By understanding how they work, recognizing real-world cases, and adopting proactive security habits, you can significantly reduce your risk of becoming the next victim.
The Two Most Dangerous Crypto Wallet Scams in 2024
Ice Phishing: Losing Control Without Knowing It
Ice phishing is a social engineering attack designed to trick users into voluntarily signing malicious blockchain transactions that grant hackers access to their wallets. Unlike traditional phishing—which steals login credentials—ice phishing manipulates users into authorizing transactions that drain their funds.
Hackers often create urgency with messages like “Limited-time NFT drop!” or “Claim your airdrop now!” These prompts lead victims to approve deceptive smart contracts that appear harmless but contain hidden permissions allowing attackers to withdraw assets.
Common Ice Phishing Tactics:
- Fake transaction requests: Malicious transactions disguised as legitimate dApp interactions.
- Deceptive approval prompts: Users are asked to “approve” a token for use on a platform, unknowingly giving full spending rights to a hacker.
- Altered transaction details: The destination address or amount is changed silently during the signing process.

Real-World Case: A Hacker Stole Millions in Bored Ape NFTs
In 2022, attackers exploited a little-known feature on OpenSea to execute an ice phishing attack. They sent users a signature request that appeared to be for logging into the platform but actually authorized the transfer of high-value NFTs—like Bored Ape Yacht Club—for zero ETH.
Because blockchain signatures are often long strings of unreadable code, most users don’t review them thoroughly. Once signed, the transaction gave hackers unrestricted access to transfer the NFTs immediately. This incident highlighted how easily trust in familiar platforms can be weaponized.
Another Major Breach: $121 Million Lost in 10 Hours
In November 2021, hackers compromised Badger DAO’s frontend by stealing Cloudflare API keys. They injected malicious JavaScript into the official website that prompted users to sign what looked like routine transactions. In reality, these approvals allowed the attackers to drain connected wallets.
Within just 10 hours, nearly 200 wallets were emptied, totaling around $121 million in cryptocurrency. This case underscores how even reputable DeFi protocols can become vectors for ice phishing when their infrastructure is breached.
Address Poisoning: Fake Wallet Addresses That Look Real
Address poisoning (also known as "zero-transfer" or "address spoofing") relies on psychological manipulation rather than direct hacking. Since wallet addresses are long alphanumeric strings (e.g., 0xAbC...123), users rarely verify them character by character. Scammers exploit this by sending tiny or zero-value transactions from addresses that closely resemble legitimate ones.
Once the fake address appears in your transaction history, you might accidentally copy it during a future transfer—sending your funds directly to the scammer.
How Zero-Transfer Attacks Work:
- The attacker identifies a wallet frequently used for transactions.
- They generate a similar-looking address (e.g., changing
atoo, or adding/removing one digit). - A 0 ETH or 0 USDT transaction is sent from this fake address to your wallet.
- When you later make a withdrawal, you may unknowingly copy the poisoned address from your history.
For example:
- Your real address ends in
...0451cb - The scammer sends 0 USDC from an address ending in
...ff451cb - At a glance, they look identical—but sending funds to the fake one means irreversible loss.
Real Incident: A Trader Lost $68 Million in WBTC
In May 2024, a crypto trader fell victim to an address poisoning attack after transferring funds normally. Within minutes, a 0 ETH transaction appeared from a nearly identical address. Mistaking it for a previous counterparty, the user copied it and sent 1,155 WBTC—worth approximately $68 million—to the attacker’s wallet.
Even Binance nearly became a victim in 2023 when a senior trader almost transferred $20 million in USDT to a spoofed address. Fortunately, the mistake was caught in time, and Tether froze the tokens before the funds could be moved.

How to Protect Yourself: 4 Essential Security Habits
Cybersecurity starts with awareness and discipline. Here are four proven practices to safeguard your crypto assets:
1. Never Trust Unverified Links or Prompts
Always double-check URLs before connecting your wallet. Avoid clicking links in emails, DMs, or social media posts—even if they appear to come from trusted sources. Instead, manually type in the official website address.
2. Enable Two-Factor Authentication (2FA)
Use authenticator apps like Google Authenticator or Authy (not SMS) to add an extra layer of protection against unauthorized access.
3. Regularly Audit Wallet Permissions
Check which dApps have approval to spend your tokens. Revoke access from unused or suspicious platforms using tools like Revoke.cash or built-in wallet features.
4. Verify Full Wallet Addresses Before Sending
Never rely solely on transaction history for address copying. Always compare the full address—especially the first and last six characters—or use a whitelist system where approved addresses are saved securely.
Advanced Protection: Use Tools Like XRAY to Detect Risky Addresses
To combat rising fraud, advanced tools are now available to help both individuals and institutions identify risky addresses before damage occurs.
One such solution is XRAY, a blockchain wallet analysis tool that allows users to:
- Identify whether an address belongs to a major exchange (e.g., Binance, Coinbase)
- Detect potential scams or suspicious activity
- Verify if a romantic interest’s wallet actually holds funds (useful against “pig-butchering” scams)
By simply pasting an address into the XRAY bot on LINE, users can gain insights into its risk profile—helping prevent irreversible losses from address poisoning or impersonation scams.
Law enforcement agencies also use such tools to trace illicit fund flows and respond faster to crypto-related crimes.

Frequently Asked Questions (FAQ)
Q: What’s the difference between phishing and ice phishing?
A: Traditional phishing steals your private keys or passwords through fake websites or malware. Ice phishing doesn’t steal credentials—it tricks you into approving a malicious blockchain transaction that gives attackers spending control over your assets.
Q: Can I recover funds after an ice phishing attack?
A: Once a transaction is confirmed on-chain, recovery is extremely unlikely. Unlike banks, blockchains don’t offer chargebacks. Prevention through careful verification is critical.
Q: Is address poisoning only dangerous for large transfers?
A: No. Even small transfers can be targeted. The scammer’s goal is to get their fake address into your history so you might reuse it later for bigger transactions.
Q: Are hardware wallets immune to these attacks?
A: Hardware wallets protect private keys but cannot stop you from approving malicious transactions. If you sign a harmful contract or send funds to a fake address, the wallet will execute it as instructed.
Q: How can I tell if an approval request is dangerous?
A: Look for red flags: unlimited token allowances, unfamiliar contract names, or requests from unknown dApps. Use tools like Blockaid or MetaMask’s built-in scanner to assess risks before signing.
Q: Does checking the first and last few characters of an address guarantee safety?
A: Not anymore. Scammers now craft addresses that match both ends exactly (e.g., same first 6 and last 6 characters). Always verify the entire string or use trusted verification tools.
By staying informed and adopting secure habits, you can confidently navigate the world of crypto without falling prey to increasingly clever scams. As cyber threats evolve, so must our defenses—knowledge, vigilance, and smart tools are your best allies in protecting digital wealth.
