What Is a Wallet Drainer and How Does It Work?
A wallet drainer is a malicious smart contract or script designed to steal all cryptocurrency and NFTs from a connected wallet. Unlike simple phishing that tries to steal your seed phrase, drainers exploit token approvals to transfer funds without your explicit permission for each transaction.
How Wallet Drainers Operate:
When you connect your wallet to a malicious site, the drainer requests approval to spend tokens from your wallet. Many users click “Approve” without reading the permissions. Once approved, the drainer can transfer all tokens of that type from your wallet to the scammer’s address. Modern drainers use advanced techniques including:
- Permit2 signatures that look like regular approvals
- Blind signing attacks on hardware wallets
- SetApprovalForAll for NFTs (drains entire NFT collection)
- Multi-chain drainers that attack across Ethereum, BNB Chain, Polygon, Arbitrum, and Optimism simultaneously
- Gasless approvals that execute without your awareness
- Proxy contracts that hide the ultimate destination of stolen funds
– Average loss per victim: $8,500
– Largest single drain in 2026: $2.4 million
– Daily attacks: 150-300 unique drainer sites
– Most targeted chain: Ethereum (63% of attacks)
– Second most targeted: BNB Chain (22% of attacks)
Recent Wallet Drainer Attacks (2025-2026)
Understanding recent attacks helps identify patterns and avoid similar scams. Here are major wallet drainer incidents from the past 18 months:
Major Incidents:
January 2026 – Fake zkSync Airdrop Drainer: Scammers created over 50 fake zkSync claim portals promoted through Google ads. Estimated $15 million stolen from 3,000+ victims within 72 hours before takedown.
December 2025 – Inferno Drainer Returns: The infamous Inferno Drainer infrastructure re-emerged with new domains after previous takedown. Stole $22 million in two weeks targeting LayerZero and EigenLayer claimants.
October 2025 – Discord Support Scam: Hackers compromised 200+ Discord servers including major NFT projects. Fake support accounts convinced users to connect wallets for “verification,” draining $8 million.
August 2025 – Google Ad Poisoning Campaign: Attackers spent $500,000 on Google ads for “Pudgy Penguins” and “Azuki” claiming emergency migrations. Resulted in $35 million stolen from NFT holders.
June 2025 – Multichain Drainer Exploit: A single drainer contract affected Ethereum, BNB Chain, Polygon, Arbitrum, and Optimism simultaneously. Victims lost funds across all chains where they had approvals.
April 2025 – MS Drainer Shutdown: Following law enforcement action, the MS Drainer service (responsible for $300 million in theft) shut down, but new variants emerged within weeks.

Google Ad Phishing: How Scammers Hijack Search Results
Google Ads has become the primary attack vector for wallet drainers. Scammers spend thousands of dollars daily on sponsored ads that appear ABOVE legitimate search results. Here is how the attack works:
Step by Step Attack Method:
Step 1: Scammer creates a fake airdrop claim site that perfectly mimics the official project website including logos, colors, and content.
Step 2: Scammer runs Google Ads bidding on keywords like “zkSync airdrop claim” or “Starknet eligibility check.”
Step 3: When you search for the legitimate airdrop, the fake sponsored result appears at the top of Google search results, often with a green checkmark ad badge that looks official.
Step 4: You click the sponsored result thinking it is legitimate because it appears above the organic result.
Step 5: The fake site prompts you to “connect wallet to check eligibility” and requests approval to spend tokens.
Step 6: Once you approve, the drainer transfers all tokens from your wallet within seconds.
Real Example from January 2026:
A scammer spent $15,000 on Google Ads for “zkSync claim” keywords. The fake site appeared above the official zkSync link for 48 hours before Google removed the ads. During that time, over 2,000 victims lost approximately $8 million combined.
How to Protect Yourself from Google Ad Scams:
Never click sponsored results for any crypto airdrop or wallet related search. Always type the official URL directly into your browser or use bookmarks. Install an ad blocker like uBlock Origin to hide sponsored results entirely. Verify the URL matches the official project domain exactly, including correct spelling and .io/.org/.com extensions.
Discord and Telegram Hack Methods
Discord and Telegram remain favorite hunting grounds for wallet drainer scammers. Understanding their methods helps you avoid falling victim:
Method 1: Compromised Server Admin Accounts
Scammers hack Discord moderators or admins through session token theft. Once compromised, they post fake “emergency claim” announcements in official announcement channels. Because the message comes from a trusted admin account, users believe it is legitimate. Always verify announcements from multiple sources including Twitter and official websites.
Method 2: Fake Support Scams
After you post a question in any crypto Discord or Telegram channel, scammers instantly DM you pretending to be official support. They claim there is an issue with your wallet or that you need to “verify” your wallet to receive an airdrop. They send a malicious link that drains your wallet. Remember: legitimate support will NEVER DM you first or ask you to connect your wallet to a verification site.
Method 3: Verification Bot Scams
Scammers add fake “verification” bots to servers that require you to connect your wallet to “verify humanity” or “sync roles.” These bots are actually wallet drainers. Never connect your wallet to any Discord verification system unless it is a well-known service like Collab.Land (and even then, verify the URL).
Method 4: Giveaway and Whitelist Scams
Scammers announce fake giveaways or whitelist opportunities requiring wallet connection to “register.” The registration page is a drainer. Legitimate giveaways never require wallet connection for entry.
Red Flags on Discord and Telegram:
Any message pressuring you to act immediately or lose an opportunity is almost certainly a scam. Messages containing shortened links (bit.ly, tinyurl, etc.) should never be trusted. Any request to “connect wallet to verify” is always a scam. Any announcement of an airdrop that was not previously announced on official Twitter is a scam.
Twitter Impersonation Scams
Twitter remains a primary platform for wallet drainer promotion despite ongoing enforcement efforts. Scammers use multiple techniques to trick users:
Verified Impersonation Accounts:
Scammers pay for Twitter Blue verification on accounts with usernames like @Starknet_Official or @zkSync_Claims. These accounts look legitimate because they have blue checkmarks. They reply to real project tweets with fake claim links. Always check the account’s handle against the official handle listed in the project’s Linktree or official website. A single underscore or extra character indicates a scam.
Compromised Influencer Accounts:
Scammers hack established crypto influencers with large followings. They post fake airdrop announcements from the compromised account. Followers trust the announcement because it comes from a familiar source. Even trusted accounts can be compromised. Always verify airdrop announcements on the official project website before connecting any wallet.
Trend-Jacking Scams:
When a legitimate airdrop is trending on Twitter, scammers flood the hashtag with fake claim links. They use automated accounts to reply to every tweet about the airdrop with malicious links. Never click links in replies, only in the original tweet from the official project account.
Quote Tweet Scams:
Scammers quote tweet legitimate project announcements with comments like “Claim here:” followed by a malicious link. The quote tweet appears in search results and can trick users who see the project name and assume the link is legitimate.
How to Verify Official Twitter Accounts:
Check the account creation date. Official project accounts were created before the project launched. Scam accounts are usually days or weeks old. Check follower count. Official projects have tens or hundreds of thousands of followers. Scam accounts have few followers. Check the account’s Linktree or website link. Verify that domain matches the official project domain exactly.
Technical Explanation: How Drainers Bypass Wallet Security
Understanding the technical mechanisms behind wallet drainers helps you recognize and avoid them. This section explains how modern drainers operate:
Token Approval Exploits:
When you approve a smart contract to spend a specific token, you are granting permission for that contract to transfer that token from your wallet. Legitimate dApps use this for swaps, lending, and deposits. Drainers use the same mechanism but with malicious contracts. Once approved, the drainer can call the transferFrom function to move your tokens to the scammer’s address without further approval from you.
SetApprovalForAll for NFTs:
NFTs use a different approval mechanism called setApprovalForAll. This grants a contract permission to transfer ALL NFTs in your wallet. One approval can drain your entire NFT collection worth millions. Many drainers request this approval under the guise of “listing” or “migrating” your NFTs.
Permit and Permit2 Attacks:
EIP-2612 permit signatures allow token approvals without an on-chain transaction. You simply sign a message off-chain, and the contract can execute the transfer. Drainers present a signature request that looks like a regular wallet signature but actually approves spending. Users sign without realizing they are granting permission. Permit2, introduced by Uniswap, extends this functionality and has been exploited by sophisticated drainers.
Blind Signing on Hardware Wallets:
Hardware wallets like Ledger and Trezor display transaction details on a small screen. Drainers use complex contract interactions that show up as unreadable data on these screens. Users see “Contract Interaction” without understanding what they are approving. This “blind signing” is responsible for many high-value drains. Only sign transactions you fully understand.
Proxy Contracts and Address Poisoning:
Modern drainers use proxy contracts where the ultimate destination address is not visible in the initial approval. The approval goes to a proxy that can be updated to point to any address. After you approve, the scammer updates the proxy to point to their drainer address. Your approval that seemed safe becomes dangerous.
Multi-Chain Drainers:
Advanced drainers use cross-chain approvals to drain funds across multiple networks. If you have approved the same wallet address on Ethereum, BNB Chain, and Polygon, a single approval can drain all three chains simultaneously. Always revoke approvals on every chain you use.
10 Signs You Are on a Wallet Drainer Site
Recognizing malicious sites before connecting your wallet is your best defense. Look for these warning signs:
Sign 1 – Suspicious URL: The domain has typos like “starknet-claims.org” instead of “starknet.io” or uses .org, .net, .xyz when the official site uses .io or .com. Always check the URL carefully before connecting.
Sign 2 – Urgency Language: The site says “Claim within 24 hours” or “Final chance” or “Limited slots remaining.” Scammers create urgency to prevent you from thinking critically. Legitimate airdrops give weeks or months for claims.
Sign 3 – No Social Proof: The site lacks links to official Twitter, Discord, or GitHub. Or the social links go to fake accounts. Check that social media links lead to verified accounts with large followings.
Sign 4 – Connection Required Immediately: The site asks you to connect your wallet before showing any information. Legitimate sites show eligibility information first or allow you to check without connecting.
Sign 5 – Unusual Permission Requests: When connecting, the wallet shows requests for “Set Approval For All” (for NFTs) or approval for token spending limits. Legitimate eligibility checks do not require these permissions.
Sign 6 – No Whitepaper or Documentation: The site has no technical documentation, team information, or roadmap. Legitimate projects provide extensive documentation.
Sign 7 – Grammar and Spelling Errors: Professional projects hire professional writers. Multiple grammar errors, awkward phrasing, or inconsistent terminology indicate a rushed scam site.
Sign 8 – No GitHub or Open Source Code: Legitimate blockchain projects are open source. If the site cannot link to verified GitHub repositories, it is likely a scam.
Sign 9 – Copy-Pasted Design: The site looks identical to another project’s site with only the name changed. Scammers reuse templates. Compare the design to the official project site you know.
Sign 10 – Found Through Google Ad or DM: If you arrived via a sponsored Google result or a direct message, treat the site as suspicious. Legitimate projects rely on organic traffic and official announcements, not paid ads for airdrop claims.
Immediate Steps If You Connected to a Malicious Site
If you suspect you have connected your wallet to a drainer site, time is critical. Follow these steps immediately:
Step 1: Disconnect Your Wallet
Immediately disconnect your wallet from the site. In MetaMask, click on the site connection in the wallet interface and select disconnect. In other wallets, navigate to connected sites and remove the suspicious site. This prevents immediate additional transactions but does NOT revoke existing approvals.
Step 2: Do NOT Sign Any More Transactions
Do not approve any more requests from any site until you have completed all security checks. Every additional signature could be another approval for the drainer.
Step 3: Move Remaining Funds Immediately
If you have funds remaining in the compromised wallet, move them to a new wallet address immediately. The drainer may have approval to spend specific tokens but may not have drained everything yet. Create a new wallet, generate a new seed phrase, and transfer all remaining assets including ETH for gas fees.
Step 4: Revoke All Token Approvals
Use Revoke.cash, Etherscan token approval checker, or Rabby Wallet’s approval manager to revoke all approvals. Revoke every approval, even for tokens that have already been drained. Drainers can return for more if approvals remain active.
Step 5: Check for Hidden Approvals
Some drainers use non-standard approval methods. Check for permit signatures and permit2 approvals which may not appear in standard approval checkers. Use specialized tools like ApprovalRevoker or check Etherscan for “Permit” transactions.
Step 6: Monitor Your Wallet Address
Continue monitoring the compromised wallet address for unexpected activity. Set up alerts on Etherscan or similar block explorers. Drainers sometimes wait days or weeks before executing transfers.
Step 7: Report the Incident
Report the malicious site to security tools like Pocket Universe, Wallet Guard, and Scam Sniffer. Also report to the project being impersonated so they can issue warnings to their community.
Step 8: Never Use That Wallet Again
Even after revoking approvals, the wallet address is compromised. Create a new wallet with a new seed phrase and never use the compromised address again. Some drainers install backdoors that persist beyond revocations.
How to Revoke Malicious Token Approvals
Revoking approvals is the most critical step after connecting to a malicious site. Here are detailed instructions for each method:
Method 1: Using Revoke.cash (Easiest for Beginners)
Step 1: Go to revoke.cash (type manually, never click links).
Step 2: Connect your wallet (use the compromised wallet address).
Step 3: Select the network where you gave approvals (Ethereum, BNB Chain, Polygon, etc.).
Step 4: Review the list of token approvals and contract approvals.
Step 5: Click “Revoke” next to any suspicious approvals, especially recent ones or unknown contract addresses.
Step 6: Confirm the revocation transaction in your wallet (gas fee required).
Step 7: Repeat for every network where you have approvals.
Method 2: Using Etherscan (More Technical)
Step 1: Go to etherscan.io and search for your wallet address.
Step 2: Click on the “Token Approvals” tab (under More dropdown).
Step 3: Review the list of approved contracts and token allowances.
Step 4: Click “Revoke” next to each approval you want to remove.
Step 5: Confirm the transaction in your wallet (gas fee required).
Method 3: Using Rabby Wallet (Built-in Protection)
Step 1: Install Rabby Wallet browser extension.
Step 2: Import your wallet using your seed phrase (only do this if you have secured your funds).
Step 3: Click on the “Approval Manager” in the wallet interface.
Step 4: Review all approvals across all networks in one dashboard.
Step 5: Revoke any suspicious approvals.
What to Look For When Revoking:
Revoke any approval to an unknown contract address. Revoke any approval with unlimited spending allowance (shows as “Unlimited” or very high number). Revoke any approval created around the same time you visited the suspicious site. Revoke any approval for SetApprovalForAll on NFTs. When in doubt, revoke everything and re-approve only the dApps you trust.
Prevention: How to Never Get Drained Again
Prevention is far better than recovery. Implement these security practices immediately:
Use a Hardware Wallet for Large Holdings
Ledger and Trezor devices require physical confirmation for every transaction. Even if you accidentally connect to a drainer site, the drainer cannot execute transfers without you pressing the button on the device. Never approve blind signatures. Always verify transaction details on the device screen. Keep your seed phrase offline and never enter it into any computer or website.
Use a Dedicated Burner Wallet for Airdrop Farming
Create a separate hot wallet for airdrop interactions. Keep only the minimum funds needed for gas fees in this wallet. If this wallet gets drained, your losses are limited to gas fees and any tokens in that wallet. Never connect your main holdings wallet to any airdrop site or unknown dApp. Consider this the most important rule of airdrop safety.
Install Security Browser Extensions
Wallet Guard blocks known malicious sites and simulates transactions before execution. Pocket Universe provides transaction simulation and warning popups. Scam Sniffer maintains a database of malicious domains. Rabby Wallet has built-in security features including approval warnings and transaction simulation. Install all of these extensions for layered protection.
Never Click Google Ads for Crypto
Install uBlock Origin or another ad blocker to hide sponsored results entirely. Bookmark official project websites. Type URLs manually instead of searching. If you must search, scroll past sponsored results to organic results only. The organic result is usually the legitimate site.
Verify URLs Through Multiple Sources
Before connecting your wallet, verify the URL through at least two independent sources. Check the project’s Twitter bio for the official link. Check CoinGecko or CoinMarketCap for verified links. Check the project’s Discord announcements. Never trust a single source, especially search results.
Revoke Approvals Monthly
Set a recurring calendar reminder to revoke all token approvals every month. Even legitimate dApps can be hacked or go rogue. Regular revocation limits your exposure. Use Revoke.cash or Rabby Wallet’s approval manager for this monthly maintenance.
Use Multiple Wallets with Different Purposes
Create separate wallets for different activities. One wallet for long-term holdings that never connects to any dApp. One wallet for DeFi interactions with trusted protocols only. One wallet for airdrop farming with minimal funds. One wallet for NFT trading. This compartmentalization limits damage from any single compromise.
Test with Small Amounts First
Before approving any significant transaction, test with a small amount. Send $10 worth of tokens and see if they can be withdrawn. If the site is malicious, you lose only the test amount. Never approve unlimited spending allowances on new or untested dApps.
Keep Your Seed Phrase Offline Forever
Never store your seed phrase digitally. Do not take photos of it. Do not type it into any computer, phone, or website. Do not save it in cloud storage, email, or notes apps. Write it on paper or stamp it on metal and store it in a secure physical location. The only time you enter your seed phrase is when restoring a wallet, and that should happen only on the hardware wallet device itself, never on a computer keyboard.
Safest Wallets That Block Drainers
Not all wallets offer the same security features. These wallets provide the best protection against drainers:
Rabby Wallet (Strongest Security Features)
Rabby Wallet is currently the safest browser wallet for Ethereum and EVM chains. It includes transaction simulation that shows exactly what will happen when you approve a transaction. It warns about unlimited approvals and suspicious contract interactions. It has a built-in approval manager for easy revocation. It identifies known malicious contracts and blocks interactions. Rabby is highly recommended for anyone serious about airdrop safety.
MetaMask with Security Extensions
MetaMask remains the most popular wallet but lacks built-in security features. When using MetaMask, install Wallet Guard, Pocket Universe, and Scam Sniffer extensions for protection. These extensions add transaction simulation, malicious site blocking, and approval warnings. Never use MetaMask without these security layers for airdrop farming.
Hardware Wallets (Ledger and Trezor)
Hardware wallets provide the strongest protection for long-term holdings. The private keys never leave the device. Even if your computer is compromised, funds cannot be moved without physical button confirmation. However, blind signing remains a risk. Always verify transaction details on the device screen before approving. Use Ledger Live or Trezor Suite for managing assets.
Braavos and Argent X for Starknet
For Starknet users, Braavos and Argent X offer account abstraction with built-in security features including session key limits and two-factor authentication. These wallets limit the damage drainers can cause by restricting spending amounts and requiring multiple confirmations for large transfers.
Phantom for Solana
Phantom includes built-in transaction simulation and warning systems for Solana users. It flags suspicious transactions and unknown contract interactions. Phantom also offers a “Trusted Apps” feature that limits approvals to verified applications.
How to Report Wallet Drainer Sites
Reporting malicious sites helps protect the entire crypto community. Here is how to report effectively:
Report to Security Tools:
Report to Scam Sniffer at report.scamsniffer.io. Report to Pocket Universe through their Discord. Report to Wallet Guard through their website. These tools block malicious sites for all users once confirmed.
Report to Google Safe Browsing:
Use Google’s Safe Browsing reporting page at safebrowsing.google.com/safebrowsing/report_phish/. This adds the site to Google’s blocklist, preventing Chrome and other browsers from loading it.
Report to Cloudflare:
Many drainer sites use Cloudflare protection. Report abuse to Cloudflare at cloudflare.com/abuse/form. Cloudflare will terminate the site’s protection, making it inaccessible.
Report to Domain Registrars:
Identify the domain registrar using WHOIS lookup. Contact the registrar’s abuse department with evidence. Registrars including Namecheap, GoDaddy, and Porkbun will suspend malicious domains when properly reported.
Report to Project Teams:
Notify the legitimate project being impersonated via their official Twitter or Discord. Project teams can issue warnings to their communities, preventing more victims.
Report to the Community:
Post warnings on Twitter with the malicious URL (spell it as hxxps:// to prevent accidental clicks). Share in Discord scam alert channels. Contribute to community-maintained blocklists on GitHub.
Information to Include in Reports:
The malicious URL exactly as it appears. Screenshots of the fake site. Screenshots of the drainer transaction on Etherscan or other block explorers. The contract address of the drainer if known. The date and time you encountered the site. Any other identifying information about the scam operation.
Frequently Asked Questions About Wallet Drainers
Q1: Can a wallet drainer steal my funds without me approving anything?
No. Wallet drainers require you to sign an approval transaction or signature. Simply visiting a malicious site without connecting your wallet or signing anything cannot drain your funds. However, some advanced drainers use zero-click exploits that require only visiting the site. These are extremely rare and typically target specific browser vulnerabilities. Keeping your browser and wallet extensions updated prevents most zero-click attacks.
Q2: Can a hardware wallet be drained if I connect to a malicious site?
Yes, if you approve the transaction on the hardware wallet device. Hardware wallets secure your private keys but they do not prevent you from signing malicious transactions. If you press the button approving the transaction, the drainer can execute. Always verify transaction details on the hardware wallet screen. If the screen shows “Contract Interaction” without clear details, do not approve.
Q3: How do I know if my wallet has been drained?
Check your wallet balance on a block explorer like Etherscan. If you see outgoing transfers you did not authorize, your wallet has been compromised. Also check for approvals you did not create. If you see unexpected approvals, revoke them immediately even if funds remain.
Q4: Can drained funds be recovered?
Rarely. Blockchain transactions are irreversible. Once funds are transferred to the scammer’s address, they cannot be recovered unless the scammer voluntarily returns them (extremely unlikely) or law enforcement seizes the funds (possible but rare for amounts under $1 million). Some recovery services claim to help but most are scams themselves. Prevention is the only reliable protection.
Q5: Are mobile wallets safer than browser extensions?
Mobile wallets have a smaller attack surface than browser extensions because they do not interact with web pages directly. However, drainers can still trick mobile wallet users through WalletConnect sessions. Always verify transaction details on your mobile device before approving. Never approve transactions from unknown dApps.
Q6: Can a drainer steal funds from multiple chains at once?
Yes. Modern multi-chain drainers request approvals on multiple networks simultaneously. If you have approved on Ethereum, the same approval pattern can be repeated on BNB Chain, Polygon, Arbitrum, and others. Always revoke approvals on every network where you have interacted with the malicious site.
Q7: What is the difference between a drainer and a phishing site?
Phishing sites trick you into entering your seed phrase or private keys, giving the scammer full control of your wallet. Drainers keep your keys but gain approval to transfer specific tokens. Drainers are more common now because they work even on users who know never to share seed phrases.
Q8: How do I check if my wallet has malicious approvals?
Use Revoke.cash and connect your wallet. Look for approvals to unknown contract addresses, especially those created recently or with unlimited allowances. Also check Etherscan’s Token Approvals tab. Any approval you do not recognize should be revoked.
Q9: Can antivirus software detect wallet drainers?
Traditional antivirus software does not detect smart contract drainers. However, security extensions like Wallet Guard and Scam Sniffer do detect known malicious sites and simulate transactions. Install these specialized tools for crypto security.
Q10: What should I do if I accidentally approved a drainer transaction?
Move all remaining funds to a new wallet address immediately. Then revoke all approvals on the compromised wallet. Never use that wallet address again. Report the malicious site to security tools. Consider the drained funds gone and focus on securing remaining assets.
