For some months quite advanced scams have been active on the main NFT market

For some months quite advanced scams have been active on the main NFT market. One of the main NFT-related scams are Rug Pulls (buying a worthless NFT and the liquidity earned by the creators to develop the project is drained). Another classic scam is to do mint on a compromised page by giving the smart contract permission to empty your wallet with all the NFTs inside. Basically on METAMASK the mint of that NFT is not approved but a function that gives the criminals the authorization to empty the wallet.

This scam, on the other hand, is slightly more advanced, although quite similar. I would like to remind you that if a contract is malicious, its approval can allow the attacker to steal the entire collection you own. So a contract that was poorly designed could have these issues. One example is the Wyvern contracts used by Opensea, where a single attacker could have stolen all of your approved OPENSEA NFT. One of these criminals stole 10 Azuki, 8 Mfer and 3 Mutant Ape with a single signature. What you do is "approval to transfer your NFT to a new address".

SCAM OFFERS ON OPENSEA: BE CAREFUL!

This type of scam sees an NFT arrive in your wallet. If you use DeFi a lot, our address can easily end up in the hands of scammers. Address is public so nothing can be done. If I buy an NFT it results in a transaction with my address, these are easy to obtain. Receiving a free NFT is not a problem, the scam takes place the moment we get an offer to this NFT (which is usually a mint free pass). This pass comes with offers of almost 1 ETH. When you accept the offer, this message appears:

In short, it is not a real offer also because this pass (NFT) that has been airdropped in the wallet is worth nothing. However, it serves to entice the user to go mint on the criminals' site. The big offer is to make the user believe that this is something of value.

If you see carefully it is the same address (of the scammer) that sends offers to all NFT pass holders. In short, the scam is based on:

1) send 1 NFT pass,

2) make an offer of 900/1000$

3) get an error message (NFT is not transferable so it is impossible to accept the offer)

4) entice the user to go to their site to make mint

If you do mint, the only thing you will get is losing all your NFT. One of the alarm bells are the traded volumes: usually these scam collections do not have volumes.
