Phishing is a form of method that hackers and scammers use to steal your NFTs. It usually involves using a fake message sent to you regarding NFTs that leads you to click on a particular link.

This link may contain a malware or virus that could potentially hack your computer. Normally, however, clicking on such links nowadays can take you to another website, that is Asks you to enter your secret recovery phrase from your NFT or crypto wallet.

There are many instances where many people who have no knowledge of such things fall for such attacks and get their NFT and Crypto stolen.

This is dangerous and common on social media apps like Discord, where hackers create identical profile copies of different Blue Chip NFT projects and notify the user about a fake giveaway or Mint releases. Many people who fall for this have to enter their secret recovery phrase. If the victim falls for it, they will lose their NFT and crypto assets completely.

bug exploits

The more sophisticated form of theft involves hackers identifying exploitable code in websites and smart contracts. These holes in the code’s logic allow attackers to run unintended code or gain permission to do things they wouldn’t otherwise do. Recently, for example, the Treasure Marketplace ( was hit by a wave of thefts where a hacker discovered an exploit and was able to mine hundreds of NFTs for free.

These kinds of exploits are hard to avoid because they rely on the underlying code of the website and smart contract to be good, something out of the hands of the typical collector. Fortunately, as with Treasure’s market operation, NFTs were quickly returned and the situation was resolved. As the nascent NFT space takes shape, these bugs and vulnerabilities are likely to become less commonplace.

Presenting themselves as well-known investment gurus, these fake accounts are simply looking for wallet information such as seed phrases and passwords. Give these scammers enough information and they will drain your wallet of your NFTs and crypto.

Theft of works of art

A growing form of scam in the NFT space is also theft of works of art. These are collections of tokens where artists are completely unaware that their work is being used for this purpose. These often include fan art from popular games and shows or conceptual art from places like DeviantArt ( A good source of information on how to solve this form of theft is the Twitter account NFT theft (, which specializes in artists removing NFTs with their work.
