In recent months, cryptocurrency wallet thefts have surged, with high-profile cases making headlines. Even global celebrities aren't immune — in April 2022, Jay Chou (Jay Zhou), the renowned Taiwanese artist, fell victim to an NFT heist. On April 1st — ironically, April Fools’ Day — he posted on social media that his Bored Ape NFT had been stolen: “I thought it was an April Fools’ joke at first, but when I checked, it was really gone…”
Within just one hour, the NFT was resold multiple times. At market value, the stolen digital asset was worth over $500,000 USD — more than 3 million RMB.

An investigation into the incident revealed the root cause: Chou had unknowingly signed a malicious transaction that granted control of his NFT to the attacker’s wallet. Once authorized, the hacker swiftly transferred the asset out of his account.
This case highlights a growing threat in the crypto space — wallet compromise through user error or lack of awareness. While many assume blockchain technology is inherently secure, the weakest link often lies not in the network, but in how users manage their wallets.
Let’s dive into the most common ways crypto wallets are compromised and how you can protect your digital assets.
Understanding Hot Wallet Risks
Hot wallets — cryptocurrency wallets connected to the internet — offer convenience for frequent transactions but come with increased security risks. They are the most commonly targeted by attackers due to their online exposure.
Here are the primary reasons hot wallets get hacked:
1. Downloading Fake Wallet Apps
One of the most frequent causes of theft is downloading counterfeit wallet software from phishing websites. These fake apps mimic legitimate wallets almost perfectly, tricking users into installing malware that captures private keys or seed phrases.
👉 Avoid downloading malicious apps by learning how to verify official crypto tools.
Always double-check URLs before downloading any wallet. Bookmark official sites and avoid clicking on search engine ads or social media links that claim to offer “free” or “enhanced” versions of popular wallets.
2. Private Key or Seed Phrase Exposure
Your seed phrase (usually 12 or 24 words) is the master key to your wallet. If someone gains access to it, they can fully control your funds.
Common causes of exposure include:
- Storing seed phrases in unsecured locations (e.g., cloud notes, photos, plain text files)
- Falling for fake airdrop scams that prompt users to enter their seed phrase on phishing sites
- Sharing them with fraudulent customer support agents
Never share your seed phrase with anyone — no legitimate service will ever ask for it.
3. Over-Authorizing dApps and Platforms
Decentralized applications (dApps) often require wallet connectivity via tools like MetaMask. However, when users sign authorization requests without reviewing them carefully, they may unknowingly grant excessive permissions — such as unlimited token spending rights.
Attackers exploit this through signature spoofing, where a seemingly harmless action (like viewing an NFT) is actually a transaction that approves asset transfers.
Always review contract permissions before signing. Use wallet tools that show detailed transaction breakdowns and revoke unnecessary authorizations regularly.
4. Vulnerabilities in Wallet Software
Even trusted wallet providers can suffer from security flaws. Hackers continuously scan for bugs in smart contracts or app code that could allow unauthorized access.
While developers work hard to patch vulnerabilities, zero-day exploits (previously unknown flaws) do exist. This means no software is 100% safe — especially if not updated regularly.
Keep your wallet apps and firmware up to date, and monitor official channels for security advisories.
Cold Wallets Aren’t Foolproof Either
Cold wallets — hardware devices that store private keys offline — are widely regarded as the most secure option for long-term crypto storage. However, they are not immune to threats.
Buying Counterfeit Hardware Wallets
Some users attempt to save money by purchasing secondhand or discounted cold wallets from unofficial sources. This opens the door to sophisticated scams.
For example, scammers may:
- Buy a genuine hardware wallet
- Record its original seed phrase and recovery details
- Re-seal and resell it at a discount with fake labels
Once you use this tampered device, any funds sent to it are instantly accessible to the scammer.
Always buy hardware wallets directly from official manufacturers or authorized retailers. Never use a device that has been pre-initialized or shows signs of tampering.
Best Practices for Wallet Security
While no system is completely invulnerable, following these guidelines can drastically reduce your risk:
- Use hardware wallets for large holdings – Store significant assets offline.
- Verify all URLs and downloads – Ensure you’re using authentic wallet software.
- Never share your seed phrase – Not with anyone, anywhere.
- Review transaction details carefully – Especially when interacting with dApps.
- Revoke unused dApp permissions – Use blockchain explorers or wallet tools to audit approvals.
- Enable two-factor authentication (2FA) – Where applicable, use authenticator apps instead of SMS.
- Keep software updated – Apply firmware and app updates promptly.
Frequently Asked Questions (FAQ)
Q: Can someone steal my crypto if they only know my wallet address?
A: No. Your public wallet address is meant to be shared — it’s like your bank account number. Theft occurs only if someone gains access to your private key or seed phrase.
Q: Is it safe to connect my wallet to dApps?
A: Yes, but with caution. Always verify the legitimacy of the dApp and review permission requests before signing. Avoid granting unlimited token allowances.
Q: What should I do if my wallet gets hacked?
A: Immediately stop using the compromised wallet, transfer remaining funds (if possible) to a new secure wallet, and revoke all dApp permissions. Report the incident to relevant platforms and monitor for further activity.
Q: How can I check if a dApp has malicious intent?
A: Use trusted sources like community forums, audit reports from firms like CertiK or PeckShield, and tools that analyze contract safety before interaction.
Q: Should I write down my seed phrase?
A: Yes — but store it securely offline. Avoid digital storage methods. Consider using metal backup solutions designed for long-term seed phrase preservation.
Q: Are hardware wallets hack-proof?
A: While highly secure, they can still be compromised through supply chain attacks or user error. Always verify device authenticity upon receipt.

Final Thoughts
The Jay Chou NFT theft serves as a powerful reminder: security in crypto starts with the user. Whether you're using a hot wallet for daily trades or a cold wallet for long-term storage, vigilance is key.
There’s no such thing as absolute security — only layers of protection. By understanding common attack vectors like fake apps, seed phrase leaks, over-authorizations, and counterfeit hardware, you can take proactive steps to safeguard your digital wealth.
Stay informed, stay cautious, and never underestimate the value of good security hygiene in the decentralized world.
