OpenSea Says It Patched an NFT Phishing Vulnerability

OpenSea, a popular marketplace for non-fungible tokens, has closed an NFT phishing loophole discovered by Check Point Research, a division of publicly traded security firm Check Point Software Technologies.

Check Point wrote about the discovery in a blog post on Wednesday and outlined the scam in a video, saying that clicking pop-ups associated with malicious, airdropped NFTs could have provided access to customers’ wallets.The company said that it notified OpenSea of the vulnerability on Sept. 26 and that OpenSea fixed the issue and verified the fix within an hour.“It’s important to note had an attacker attempted to take advantage of this flaw, the end user would have needed to approve the malicious transaction through a wallet signature,” OpenSea wrote in its own blog post about the issue on Wednesday. It said it hadn’t been able to identify any instances where the vulnerability was exploited.The phishing attack is a common tactic in the world of NFTs – thieves will send fishy tokens to public addresses on the Ethereum blockchain and wait for users to interact with them.Scams are still pervasive on the platform, and throughout crypto in general, as CoinDesk outlined in this piece on NFT phishing schemes.
