Many DeFi protocols give out airdrop rewards to users who interact with them, and on-chain users have become accustomed to airdrops, but some fake airdrops may hack users' wallets. These fake airdrops are generally characterized by large and compelling amounts of tokens.

If a user authorizes a contract when selling the token, it could give the issuer permission to transfer wallet assets, leading to the theft of assets.

AScoin advises that there are no airdrops that require users to credit an external wallet address in order to receive the rewards and that people should be extremely wary of airdrops that require you to transfer tokens to the project owner, as there is a high probability that they will be such scams.

The most effective way to prevent such airdrop scams is to not trust any airdrops of unknown origin, and platforms will not freely give airdrops to on-chain wallet addresses. In the face of the complicated blockchain environment, you must do a good job of accumulating security knowledge and strengthening your knowledge of anti-fraud. Do not open three-party links and authorize them at will, and do not lose and share private keys and helper words with anyone for safekeeping.
