Fake Project Airdrop Phishing Scams: Inducing Signature Authorization to Steal Wallet Assets

Who Gets Targeted

The victims are primarily new entrants or crypto holders with significant holdings who lack sufficient understanding of smart contract permissions. They generally exhibit a sense of luck and fanaticism regarding airdrop benefits, are eager to claim high-interest or risk-free tokens, and lack a deep understanding of underlying authorization mechanisms. When faced with exquisitely forged official pages and pop-up prompts, they often blindly sign authorization agreements, unaware that their wallet assets are being silently transferred, effectively handing over control of their digital assets.

骗局怎么运作

• Forging project identity and airdrop pages: Attackers register accounts on mainstream social media and communities that closely resemble well-known projects and create high-fidelity airdrop pages. The pages claim to celebrate the mainnet launch by airdropping 100,000 cryptocurrencies to early users, inducing users to click the 'Connect Wallet' button, thereby entering a smart contract trap.
• Pop-up inducements and red dot notifications to create urgency: After a user connects their wallet, a pop-up window with a red exclamation mark immediately appears, claiming that the wallet has unclaimed high-value rewards and that quantities are limited. By leveraging this visual urgency and herd mentality, attackers force users to click confirm in a hurry without carefully reading the authorization details.
• Malicious signature authorization to gain asset control: When a user clicks confirm in the wallet pop-up, they are not performing a standard transfer, but signing a 'Permit' authorization mechanism document. This mechanism allows the user to authorize the scammer's contract to control their crypto tokens. The scammer's contract then gains the highest permission to silently transfer user assets without requiring any further passwords.
• Fake tokens and slippage mechanisms to drain assets: In Solana chain fake token incidents, attackers first deposit a small amount of fake tokens into the user's wallet as bait, inducing victims to exchange them on decentralized exchanges. During the authorization process for the exchange, the malicious contract hijacks permissions through abnormal slippage settings, instantly draining all mainstream assets from the wallet.
• Phishing link proliferation and automated community harvesting: Attackers use the victim's wallet contact list or social media authorization interfaces to automatically send airdrop promotional posters containing short phishing links to other groups, forming a viral spread. The posters usually feature fake data, such as '10 million USD distributed today,' to further reinforce trust, thereby expanding the scope of the harvest and the scale of asset theft.

红旗信号（看到这些快跑）

• 🚩 The sudden appearance of unknown tokens in the wallet interface, accompanied by website links prompting users to claim or exchange rewards, is often a direct signal and warning of a fake airdrop.
• 🚩 When a pop-up signature prompt involves 'authorization' or 'unlimited allowance' wording instead of a clear, standard transfer recipient address, it is highly likely to be a malicious smart contract permission hijack.
• 🚩 Airdrop promotional activities are only published through unofficial community channels and have not been synchronized or announced on the project's official domain or verified main social media accounts.
• 🚩 Connecting a wallet requires authorization for an unknown smart contract, and the prompt box requests authorization for a range of token types far exceeding those required for the airdrop.
• 🚩 The website design is crude but features an urgent countdown timer or frequent pop-ups, urging users to confirm signatures or connect wallets as quickly as possible, using herd mentality to block rational thinking.

真实案例

• In August 2026, according to blockchain security firm SlowMist, a wave of malicious applications impersonating well-known wallets circulated in major app stores and communities, leading to the theft of assets from tens of thousands of users, with cumulative losses reaching 1.3 billion USD. Most victims were novice users who trusted installation packages shared in communities. (Source: https://news.sysxhz.com/newskx/20260810/1664010.html)
• In 2026, a blockchain security research institution disclosed a cryptocurrency phishing case involving 800 million KRW. Victims were attracted by high-interest bait and signed smart contract authorization agreements on meticulously forged phishing pages, resulting in all tokens in their wallets being hijacked and instantly transferred.
• On a day in 2026, a fake token phishing incident occurred on the Solana blockchain. Attackers used airdropped fake tokens to induce holders to exchange them on a forged decentralized exchange, triggering a malicious authorization contract that drained all assets from the victims' wallets.
• In May 2026, in the fake Jupiter airdrop CJUP phishing incident jointly warned by Solana ecosystem monitoring platform Solana Floor and WEEX, the scam group airdropped fake CJUP tokens to a large number of wallet addresses and imitated the Jupuary airdrop event. They induced users to visit phishing sites, connect wallets, and sign malicious authorizations to achieve rapid asset transfer, causing irreversible loss of digital assets for users.

• In 2026, the Tencent Cloud Developer Community released a technical defense research report, warning developers and users to be vigilant against smart contract permission hijacking under the guise of high-interest bait, and to prevent wallets from being drained via authorization signatures.
• In 2026, multiple local anti-fraud centers issued warnings, pointing out that new types of scams using airdropped tokens for phishing are spreading in crypto communities, specifically reminding users not to click on unknown links sent by strangers.

How to Protect Yourself

• ✅ When receiving unknown airdrops or seeing airdrop red dot notifications, do not click on the attached links to connect your wallet. Always verify the authenticity of the airdrop event on the project's official domain or verified official social media accounts first.
• ✅ When authorizing in a wallet pop-up, you must carefully read the authorization terms. Especially if you see wording about 'unlimited authorization' or transferring assets to unknown contracts, decisively refuse to click confirm to protect your assets.
• ✅ Use well-known security plugins that feature malicious address blocking. These tools will pop up clear red risk warnings when they detect that a user has opened a known phishing site or a high-risk authorization page.
• ✅ For large crypto assets, use cold wallets or hardware wallets for isolated storage. Never authorize any smart contract that has not undergone professional code auditing while connected to the internet.
• ✅ If you encounter unknown tokens deposited directly into your wallet, do not attempt to exchange them on any platform. The best practice is to hide or ignore the asset directly within the wallet to cut off any possibility of triggering a phishing link.
