This is a common tactic where hackers lure users to a legitimate looking website with the promise of free NFTs. Once a user tries to connect his Metamask to the website, a fake error is generated which prompts the user into entering his seed phrase. Once the user has access to your seed phrase he can gain control to your wallet and steal all your funds and NFTs.

Another way these hackers lure a user to their phishing website is by acting as support in the Telegram and Discord pages of tokens. They then lure users seeking support through private messages that ask the user to visit the phishing websites and connect their wallets to it.

Precaution: Never ever type your seed phrase. You should write your seed phrase in a piece of paper, store it safely and forget about it.

If a user is screen sharing there is an option in Metamask to reveal the seed phrase. Hackers often lurk as customer support staff in the social pages of tokens such as Telegram and Discord. They will tell the user that they will “debug” their systems by using screen share and to follow a set of instructions which would reveal the user’s seed phrase to the hacker.

Precaution: Using hardware wallets is the safest method to store your crypto and NFTs.

There are software which install backdoors to a user’s computer and gives hackers access to the user’s file system, computer memory and screen. Users should only install software after careful consideration and checking their validity. Users should never open random files and software.

Precaution: Never open suspicious files and use a hardware wallet
