What To Do If Your Crypto Wallet Is Hacked

In 2024, hackers stole $2.2 billion from the crypto space. By July 2025, $142 million had been stolen in 17 attacks, which is a 27% rise from June.

Why is this happening?

As crypto gets more popular, hackers are becoming more skilled.

In this guide, we’ll show you the steps to take if your crypto wallet is hacked, so you can take control and protect your assets.

A compromised wallet is a cryptocurrency wallet that someone else has managed to get into without your permission. When your wallet is compromised, your money and sensitive information are at risk, and you may see transactions you did not make, which can lead to losing your cryptocurrency.

Here are the main 8 signs to look for:

1. Unfamiliar Transactions

One of the first things you might notice is money disappearing from your wallet that you didn’t send. Hackers often start by moving small amounts to test access before trying to take bigger amounts.

You might also see unexpected deposits or strange conversions between coins. If your wallet balance changes without your permission, it’s a clear red flag.

2. Suspicious Login Attempts

If you get login alerts from devices or places you don’t recognize, it could mean someone is trying to get into your wallet. Multiple 2FA requests when you didn’t log in are another warning.

Hackers may try many times quickly, so repeated failed logins in your history are a strong sign.

3. Changes to Security Settings

If your password, recovery email, or security questions change without your action, your wallet could be hacked. Hackers may also turn off two-factor authentication or adjust account permissions.

4. Installation of Unfamiliar Browser Extensions

Some browser extensions steal private keys, passwords, or other wallet info. They can look normal at first. If you notice strange activity in your wallet after installing a new extension, it could be the reason for unauthorized access.

5. Phishing Emails or Messages

Hackers often send emails, text messages, or social media messages asking for passwords, private keys, or backup phrases. They look official but are fake. Sometimes these messages come after you click a link on a compromised website.

6. Slow or Unresponsive Wallet Apps

Malware or hackers can make your wallet app act strangely. If your app becomes slow, crashes, or shows wrong balances, it could mean someone is interfering with your wallet or trying to steal information.

7. Notifications From Unrecognized Devices

Many wallets alert you when a new device or location logs in. Alerts from countries you haven’t visited or devices you don’t own are strong signs someone may be accessing your wallet. Even if no money is moved yet, this is a serious warning.

8. Unexplained Account Lockouts or Password Changes

If you suddenly can’t log in or get a message that your password was changed, someone might have taken over your account. Hackers sometimes lock you out to move your funds safely.

1. If your crypto wallet gets hacked, the hacker can use your private keys to move your cryptocurrency to their own wallet.
2. Hackers can make malicious transactions from your wallet. They might send your coins to mixers or hide them using other tricks.
3. If your wallet is connected to DeFi platforms, hackers can exploit smart contract vulnerabilities to steal your assets automatically.
4. Some wallets store your personal information, like KYC (Know Your Customer) documents or linked emails. Hackers can use this info for identity theft.
5. A hack can expose your seed phrase or mnemonic phrase, giving attackers full control of your wallet. This causes financial loss and stress.
6. Hackers can change your private keys, passwords, or 2FA (two-factor authentication) settings. This can lock you out of your wallet completely.
7. If your wallet is linked to business accounts, DAO participation, or crypto exchanges, a hack can damage your reputation.
8. If your wallet interacts with DApps (decentralized applications) or smart contracts, hackers can exploit weaknesses in these contracts.

The quicker you act, the better your chances of saving your crypto.

Here are the 7 steps you should take:

Disconnect your wallet and devices

Turn off your internet right away on your phone or computer. If you use a browser wallet like MetaMask, remove the extension and go to Etherscan’s Token Approval Checker to cancel any dApp permissions the hacker might use.

On mobile, switch to airplane mode to cut off all connections instantly.

Freeze or lock your account

Big exchanges like Binance, Coinbase, or Kraken have an emergency option in their security settings to lock your account. This blocks withdrawals until you unlock it.

If your wallet app doesn’t have this feature, your top priority should be moving your funds instead.

Change your login details and security settings

Update your wallet password, email password, and recovery details. Always use Google Authenticator or Authy for two-factor authentication (2FA) instead of SMS, since hackers can hijack your phone number with a SIM swap.

If your seed phrase is stolen, that wallet is no longer safe, so you must create a new one.

Move remaining funds to a secure wallet

Send any crypto that’s still safe to a hardware wallet like Ledger or Trezor. These keep your private keys offline, so hackers can’t touch them.

If you don’t have a hardware wallet, create a brand-new hot wallet with a new seed phrase. First, do a small test transfer to be sure the new wallet is working, then move the rest.

Collect and secure evidence

Save all transaction IDs (TXIDs) from blockchain explorers like Etherscan, Blockchain.com, or BscScan. Take screenshots of every suspicious withdrawal, login alert, or strange activity.

Write down the timeline of what happened. This proof will be useful when you contact exchanges, police, or recovery services.

Scan for malware and secure your devices

Run a full check with trusted tools like Malwarebytes or Bitdefender. Look for spyware, clipboard hijackers (that secretly change copied wallet addresses), or malicious browser extensions.

Remove anything suspicious and update your computer, phone, browser, and apps so there are no weak points left.

Contact a cybersecurity professional

If you’re not very technical or if the hack looks serious, reach out to a cybersecurity or digital forensics expert. They can check how your wallet was hacked, secure your devices, and sometimes even trace stolen funds on the blockchain.

You should contact your wallet provider or exchange immediately to freeze your account. Make sure to give them all details like your wallet address, the hacker’s address, transaction IDs (TXIDs), timestamps, and screenshots of anything suspicious.

Next, file a report with your local or international cybercrime authorities.

For example: FBI IC3 (ic3.gov) in the U.S., Action Fraud (actionfraud.police.uk) in the UK, and Europol (europol.europa.eu) in Europe. Make sure you include all technical details such as TXIDs, wallet addresses, and any messages from the hacker.

You can also track your stolen cryptocurrency using blockchain explorers like Etherscan, BSCScan, or PolygonScan. If you notice the funds moving toward an exchange, alert them immediately - they might be able to freeze the funds.

Share your wallet and the hacker’s wallet addresses on Reddit, Telegram groups, or crypto forums. This can warn others and sometimes help you gather tips or info about the hacker or similar attacks.

Here are 8 ways to secure your wallet:

01 # Use a Hardware Wallet (Cold Storage)

A hardware wallet like Ledger Nano X or Trezor Model T holds your private keys offline. That means hackers cannot reach them through the internet.

These devices use secure chips and sign transactions inside the device, so your private key never leaves it. Only buy from official stores to avoid fake or tampered devices.

02 # Enable Two-Factor Authentication

2FA adds extra protection. The safest type is TOTP (Time-Based One-Time Password), which gives codes through apps like Google Authenticator or Authy.

Avoid SMS-based codes because hackers can do a SIM swap and steal them. Make sure 2FA is on for login and withdrawals on your wallet or exchange.

03 # Use Strong and Unique Passwords

Your passwords should be long and mix letters, numbers, and symbols, at least 16 characters. Use a password manager like 1Password to store the passwords.

Never reuse passwords across your wallet, exchange, or email accounts. If one gets hacked, all your accounts can be at risk.

04 # Regularly Update Your Wallet Software

Updates may improve encryption, such as AES-256, or add new safety features for your seed phrase. Always download updates from official sources and check cryptographic signatures if available. Never download from unknown links.

05 # Be Careful of Phishing Scams

Phishing is the most common way hackers steal crypto. Fake emails or websites pretend to be wallets or exchanges. Always check the website URL, make sure it has HTTPS, and consider using tools like MetaMask, PhishFort, or CryptoScamDB to block suspicious sites. Never click links in unknown messages.

06 # Store Recovery Phrase Securely

Your recovery phrase is the key to your wallet. Keep it offline, like written on paper or engraved on metal. Store it in a fireproof safe.

Never save it on your phone or computer. For extra safety, you can use Shamir Backup to split the seed into parts.

07 # Monitor Wallet Activity

Check your wallet transactions on blockchain explorers like Etherscan or Blockchain.com. Set up alerts for outgoing transactions or big balance changes. Some wallets and exchanges let you use APIs to track activity automatically.

08 # Avoid Storing Large Amounts

Exchanges are hot wallets and are online. They are easier targets for hackers or scams. Keep only small amounts for trading. Move the rest to cold storage or a multi-signature wallet, which requires multiple keys to approve transactions.

Crypto wallets are prime targets for attackers. Here are 14 common ways hackers use:

• Phishing (websites, emails, DMs) - Attackers clone wallet pages or send fake links. If you type your seed phrase or private key, it is then sent to an attacker-controlled server, so they get direct access to funds.
• Malicious Mobile/Desktop Apps - Fake wallet apps copy trusted apps. If you install one, it can run spyware that reads your keystrokes, clipboard, or auto-sends your private keys to the attacker’s server.
• Browser Extension Attacks - Malicious extensions inject JavaScript into pages you visit. They can read wallet info, change transactions before you sign, or hijack approvals in MetaMask and other Web3 tools you use.
• Malicious dApps & Smart-Contract Approvals - Attackers make contracts with hidden code. When you approve them, they get unlimited token allowance and can call contract functions to take your tokens without needing your private key.
• Seed Phrase & Private Key Leakage - Clipboard hijackers and spyware watch your copy-paste. If you save screenshots or use cloud sync, your seed or key can be exposed and accessed by remote attackers.
• SIM Swapping - Hackers trick phone companies to move your number to their SIM. They then use SMS codes to reset logins or get into wallets and exchanges tied to your number.
• Malware & Keyloggers - Remote-access trojans (RATs) and keyloggers run silently and record your typing, clipboard, and screens. They scan for wallet files and send them or the captured data straight to the attacker’s server.
• Social Engineering & Impersonation - Scammers pretend to be support or trusted people on Telegram, Discord, or Twitter. They get you to do “checks” that end with you revealing seeds or signing malicious transactions.
• Supply-Chain Attacks - Hackers compromise official wallet downloads or code libraries. Malicious updates add backdoors that quietly capture private keys or change transaction code before it hits the blockchain.
• Weak Randomness or Poor Key Storage - Wallets using weak RNG (random number generation) make predictable keys. If developers use Flawed entropy, attackers can brute-force or precompute private keys and take over wallets.
• Fake Tokens & Rug Pulls - Attackers launch tokens with hidden code. When you trade or approve them, those hidden functions let the creators siphon your funds through the token contract logic.
• Exchange Account Hacks - Exchanges keep hot wallets and may be breached. Attackers use leaked passwords, phished credentials, or insider access to drain user balances from centralized platforms on a large scale.
• Physical Theft & Coercion - Attackers steal phones, laptops, or hardware wallets. In coercion cases, people are forced to reveal seed phrases or unlock wallets under threat.
• Man-in-the-Middle on Public Wi-Fi - On open networks, attackers intercept your traffic. They can inject scripts, point you to fake nodes, or alter transaction data while it’s in transit between you and the network.

The world of cryptocurrency has many myths, especially about hacks. It is important to know the truth.

Myth 1 # Hardware Wallets Can’t Be Hacked

Many people think hardware wallets like Ledger or Trezor cannot be hacked. But no device is 100% safe. Hackers can use supply-chain attacks, fake firmware updates, or malware on your computer.

For example, in 2020, some Ledger users lost money after installing a fake browser extension. Hardware wallets are very safe, but only if you set them up and use them correctly.

Myth 2 # Exchanges Will Always Refund Stolen Crypto

Some think exchanges will always give back stolen money. This is not true. Even big exchanges have limits. Most losses cannot be reversed once the hacker moves your funds.

The 2014 Mt. Gox hack lost 850,000 BTC, and users got almost nothing. Small exchanges can collapse after a hack, too. That is why keeping big amounts in a cold wallet is safer than on an exchange.

Myth 3 # If I Have a Strong Password, I’m Safe

Passwords are important, but not enough. Hackers can use phishing, keyloggers, or SIM swaps to bypass even strong passwords.

For example, a 16-character password is useless if your email or phone is hacked. You need strong passwords, two-factor authentication, offline storage, and careful monitoring to stay safe.

Myth 4 # Crypto Is Completely Anonymous, So I Can’t Be Traced

Some people think crypto is private. But blockchain is public. Every transaction is recorded and can be traced. Authorities and blockchain experts can follow stolen funds across wallets and exchanges.

For example, in the 2021 Poly Network hack, $600 million was stolen, but almost all funds were recovered because the transactions were public.

Myth 5 # Small Amounts Don’t Matter, Hackers Won’t Target Me

Hackers often test wallets by stealing small amounts first. They do this to check access before trying to steal large sums.

Even small balances can be used for phishing or other scams. Every wallet needs protection, no matter how small your balance is.

Myth 6 # Once Funds Are Stolen, There’s Nothing I Can Do

Crypto theft is hard to reverse, but you are not powerless. Reporting the hack to exchanges, authorities, and blockchain experts can help recover money or prevent more theft.

Save all transaction IDs, hacker wallet addresses, and screenshots. Acting fast increases your chances of stopping further loss.

Myth 7 # Only Tech-Savvy People Can Be Hacked

Even experienced users can be hacked. Hackers are smart and use social tricks, fake airdrops, or scam apps. Being tech-savvy lowers risk, but does not stop it. Awareness and careful steps are just as important as knowledge.

Myth 8 # Insurance Covers All Crypto Hacks

Some wallets and exchanges offer insurance. But it often has limits. Most policies do not cover phishing, user mistakes, or third-party apps. Counting only on insurance can give false confidence.

A better way is to split your crypto between cold wallets, hot wallets, and insured platforms.

Myth 9 # Public Wi-Fi Is Safe for Wallet Access

Public networks are risky. Hackers can intercept your traffic, redirect you to fake wallet sites, or change your transactions. Even experts have lost crypto this way. Always use a VPN or avoid logging in on open networks.

What is the safest type of crypto wallet in 2025?

Cold storage wallets like Ledger or Trezor are safest. They keep private keys in secure elements (SE chips) and sign transactions offline, so your keys never leave the device.

How long does it take to trace stolen cryptocurrency on the blockchain?

Blockchain transactions are visible instantly. Recovery speed depends on the exchange's KYC/AML checks and if the hacker uses mixers, tumblers, or privacy coins.

Is using a VPN enough to protect my crypto wallet from hackers?

No. VPNs protect against man-in-the-middle (MITM) attacks but cannot stop clipboard hijackers, keyloggers, or malicious smart contract approvals. Use them with hardware wallets and anti-malware.

Can hackers still access my wallet if I change my password and 2FA?

Yes, if they already have your seed phrase or private keys. Wallet security depends on cryptographic keys, not just login details.

What should I avoid doing immediately after a wallet hack?

Avoid logging back in with the same device. If malware or a RAT (remote-access trojan) is installed, the hacker can still watch and steal new credentials.

How do I choose between a hardware wallet and a multi-signature wallet for safety?

Hardware wallets protect individuals. Multi-sig wallets like Gnosis Safe are better for teams since they require multiple signatures before a transaction can go through.

Can a crypto wallet be hacked?

Yes. No wallet is fully hack-proof.

Can someone steal my crypto if they have my wallet address?

No. Wallet addresses are public by design. To move funds, hackers need your private key, seed phrase, or a signed smart contract approval.

Which crypto platform has never been hacked?

No major platform is 100% hack-free, but some, like Kraken and Gemini, have strong records because of strict custody policies, cold storage, and SOC 2 audits.

Can police or authorities really help if my wallet is hacked?

Yes. Agencies like the FBI IC3 and Europol work with blockchain analytics firms such as Chainalysis and Elliptic to track funds across chains and exchanges.

Crypto wallet hacks are happening more often, but if you know the signs and act quickly, you can prevent major losses.
