According to The edgeA bot in the channel made a false announcement that the NFT Market was partnering with YouTube and that users would have to click on a “YouTube Genesis Mint Pass” to get one of 100 free NFTs before they are gone forever.
Just like cybercriminals often do in phishing emailsthis message brought a sense of urgency to make users click on a link to a site that blockchain security firm PeckShield has now flagged as a phishing site.
At the same time, as the NFT space moves quite quickly, users knew from past experience that they only had a limited time to claim one of the free NFTs and probably didn’t want to miss out.
While the malicious messages have been removed from OpenSea’s Discord channel and the phishing site has also been removed, one user said they lost NFTs in the incident and pointed to an address on the blockchain that belonged to the responsible cybercriminals.
View the address on Etherscan.io or any competing NFT marketplace rare shows that 13 NFTs were actually transferred by five users around the time of the attack and based on their prices when they were last sold, all five NFTs appear to be worth just over $18k.
While OpenSea has not yet explained how its Discord channel was hacked, one possible explanation is that the cybercriminals webhook functionality that organizations use to monitor bots posting on their channels.
In a statement to The edgeOpenSea spokesperson Allie Mack provided further details on how the company responded to the incident, saying:
“Last night, an attacker was able to post malicious links in several of our Discord channels. We noticed the malicious links shortly after they were posted and immediately took action to remedy the situation, including removing the malicious bots and accounts. We have also warned our community through our Twitter support channel not to click on links in our Discord. Our preliminary analysis shows that the attack had a limited impact. We are currently aware of fewer than 10 affected wallets and stolen items worth less than 10 ETH.”
