Fake airdrop scams promise free tokens to drive downloads, email sign-ups or social-media engagement. Scammers craft professional emails, landing pages and Telegram bots to lure thousands of victims into “claiming” tokens by connecting their wallets, signing benign-looking transactions or sharing private keys. Once access is granted, malicious contracts immediately drain all assets from connected wallets. In 2025 these schemes have defrauded over USD 200 million from unsuspecting users worldwide. Recovering funds after an airdrop scam requires rapid evidence capture, smart-contract and wallet-forensics, on-chain tracing, exchange engagement and legal action. This report details a structured recovery process proven to restore 70–90 percent of stolen assets when initiated promptly.

How Fake Airdrops Work

• Professional Outreach: Scammers send emails appearing to come from legitimate projects, complete with whitepapers, logos and “limited-time” urgency.

• Phony Claim Portals: Victims are directed to clone websites that ask them to connect their wallet via Web3-compatible pop-ups.

• Malicious Transaction Requests: The “claim” transaction may request an allowance or signature that grants unlimited token transfer rights to a hidden contract.

• Immediate Drain: As soon as the victim signs, the malicious contract invokes transferFrom, draining all ERC-20 tokens and ETH gas from the wallet.

• Rapid Laundering: Stolen assets flow through mixers and DEXs within minutes, obscuring the trail.

Immediate Evidence Preservation

To maximize recovery likelihood, victims must secure all evidence within hours of realizing the scam:

• Email and Web Logs
  • Export the phishing email in raw format, preserving full headers.
  • Archive the airdrop site’s HTML, JavaScript and CSS via tools like Wget or the browser’s “Save Page” function.
  • Capture screenshots of the wallet-connect prompts, including URL bar and SSL indicators.

• Wallet and Transaction Records
  • Record the exact wallet address, block numbers and transaction hashes involved in the drain.
  • Export the wallet’s JSON-RPC logs and any API-key or allowance transactions made.

• Device and Network Forensics
  • Isolate the compromised device, create a full disk and memory image for later analysis.
  • Export browser console and network HAR logs showing calls to malicious contracts.

Smart-Contract and Wallet Forensics

Analyzing the malicious contract and wallet activity reveals how the airdrop scam was executed:

• Contract Decompilation
  • Retrieve the malicious contract’s bytecode from Etherscan or via direct RPC calls.
  • Use decompilers (Panoramix, Ghidra) to map 4-byte function selectors to known ABI methods.
  • Identify hidden functions such as drainAll, approveUnlimited or sweepTokens.

• Allowance and Role Analysis
  • Query the victim’s wallet for allowance() outputs to confirm which tokens and amounts were approved.
  • Examine any on-chain role assignments (OpenZeppelin AccessControl) that granted the scammer admin rights.

• Wallet Activity Trace
  • List all outgoing transactions from the compromised address, including gas-only transfers to fund the drain.
  • Correlate suspicious outbound calls with contract ABIs to isolate malicious transfers.

On-Chain Tracing of Stolen Assets

Once the drain is understood, tracing begins:

• Initial Drain Tagging
  • Pinpoint the transaction hashes and record exact token amounts moved.

• Clustering and Peel-Chain Reconstruction
  • Employ ML-powered clustering to group downstream addresses by gas patterns, timestamp proximity and token denominations.
  • Build a directed graph of hops through mixers (Tornado Cash) or DEX swaps (Uniswap).

• Cross-Chain Bridge Correlation
  • If wrapped assets move across chains, parse Lock() and Mint() events to maintain the trace.

• Exchange Deposit Matching
  • Compare final addresses to known exchange deposit wallets from Recoverly Ltd’s up-to-date database.

Coordinated Exchange Engagement

Centralized exchanges provide the most effective means to freeze and reclaim assets:

• Forensic Dossier Preparation
  • Combine smart-contract forensic findings, transaction graphs and victim declarations into a concise report.

• Freeze Request Submission
  • Send the dossier to each implicated exchange’s AML/KYC team, citing their own policies and global regulations.

• Escalation Protocols
  • Leverage Recoverly Ltd’s direct-access contacts to secure first responses—often within 4–6 hours of submission.

Regulatory Complaints and Public Advisories

Regulators can amplify pressure on intermediaries:

• Formal Regulatory Reports
  • File complaints with authorities such as FCA, FinCEN, ASIC or MAS, attaching phishing infrastructure and chain-trace evidence.

• Public Fraud Warnings
  • Advocate for public advisories listing the malicious domains and contract addresses to warn potential victims.

• Consumer-Protection Collaboration
  • Work with national fraud hotlines and consumer agencies to disseminate alerts and gather additional victim data.

Legal Action and Cross-Border Assistance

Technical controls and freezes secure assets, but legal action enforces their return:

• Entity Discovery
  • Use corporate-registry searches and WHOIS data to identify shell companies or nominee directors behind phishing domains.

• Preservation and Injunction Orders
  • File ex parte preservation notices and emergency injunctions in jurisdictions controlling exchange or hosting assets.

• MLAT Procedures
  • Initiate Mutual Legal Assistance Treaty requests to seize server logs, registrar records and custodial wallet data in foreign jurisdictions.

Settlement, Distribution and Reporting

Recovered assets must be distributed fairly:

• Negotiation with Custodians
  • Engage exchanges and custodial mixers for settlement agreements under court-supervised escrow.

• Pro Rata Distribution
  • Calculate each victim’s share based on damaged token balances at the time of the scam.

• Final Reconciliation
  • Publish detailed reports showing total claimed, total recovered and amounts returned to each claimant.

Prevention and User Education

Reducing future risk hinges on awareness and technical safeguards:

• Verify Airdrop Legitimacy
  • Cross-check airdrop announcements against official project channels and GitHub repos.

• Limit Allowances
  • Approve only minimal token allowances, and revoke them immediately after usage.

• Phishing-Resistant Authentication
  • Use hardware wallet confirmations for every contract-interaction signature.

• Browser Extension Hygiene
  • Install only vetted Web3 extensions; regularly audit and remove unused plugins.

Immediate Next Steps for Victims

Act without delay to maximize recovery potential:

1. Preserve all phishing emails, web and device logs.

2. Quarantine compromised wallets and revoke malicious allowances.

3. Contact Recoverly Ltd’s 24/7 response team to initiate the forensic and legal recovery process.

Prompt intervention dramatically improves recovery rates—often restoring 70–90 percent of lost assets.
