OpenSea’s official Discord compromised in a phishing attack that stole

OpenSea’s official Discord compromised in a phishing attack that stole at least $18k worth of NFTs

Even the biggest NFT marketplace can’t keep its channel safe from scammers

Around 4:30AM ET on Friday, the official Discord channel for OpenSea, the world’s largest NFT marketplace, joined the growing list of NFT communities that have exposed participants to phishing attacks.

In this case, a bot made a fake announcement about OpenSea partnering with YouTube, enticing users to click on a “YouTube Genesis Mint Pass” link to snag one of 100 free NFTs with “insane utility” before they’d be gone forever, as well as a few follow-up messages. Blockchain security tracking company PeckShield tagged the URL the attackers linked, “youtubenft[.]art” as a phishing site, which is now unavailable.

While the messages and phishing site are already gone, one person who said they lost NFTs in the incident pointed to this address on the blockchain as belonging to the attacker, so we can see more information about what happened next. While that identity has been blocked on OpenSea’s site, viewing it via Etherscan.io or a competing NFT marketplace, Rarible, shows 13 NFTs were transferred to it from five sources around the time of the attack. They’re now also reported on OpenSea for “suspicious activity” and, based on their prices when last sold, appear to be worth a little over $18,000.

This kind of intermediary attack in which scammers exploit NFT traders who are looking to capitalize on “airdrops” has become common for prominent Web3 organizations. It’s common for announcements to appear out of the blue, and the nature of the blockchain may give some users reasons to click first and consider the consequences later.

Beyond the desire to snag rare items, there’s the knowledge that waiting can make minting your NFT amid a rush much slower, more expensive, or even impossible (if you run out of funds during the process). If they’ve left any items or cryptocurrency in their hot wallet that’s connected to the internet, then coughing up login details to a phisher could give them away in seconds.

In a statement to The Verge, OpenSea spokesperson Allie Mack confirmed the incident, saying, “Last night, an attacker was able to post malicious links in several of our Discord channels. We noticed the malicious links soon after they were posted and took immediate steps to remedy the situation, including removing the malicious bots and accounts. We also alerted our community via our Twitter support channel to not click any links in our Discord. We have not seen any new malicious posts since 4:30am ET.”

“We continue to actively investigate this attack, and will keep our community apprised of any relevant new information. Our preliminary analysis indicates that the attack had limited impact. We are currently aware of fewer than 10 impacted wallets and stolen items amounting to less than 10 ETH,” says Mack.
