Crypto data websites Etherscan, CoinGecko, DeFi Pulse and others reported incidents of a malicious pop-up prompting users to connect their MetaMask wallets.
The phishing attack appears to come from a domain displaying the Bored Ape Yacht Club logo. As of press time, the site tied to the domain appeared to be taken down. According to a WHOIS lookup, the domain was registered today around 3 p.m. ET.
"We are investigating the root cause of this attack to fix it as soon as possible," CoinGecko founder Bobby Ong told CoinDesk in a Telegram message.
"The situation is most likely caused by a malicious ad script by Coinzilla, a crypto ad network - we have disabled it now," said Ong. "We are monitoring the situation further."
In a tweet, Etherscan urged users to "not confirm any transactions" that popped up on its website.
