Clones websites of Blockworks and Etherscan have popped up to share fake news of a $37M Uniswap approval exploit, scaring readers into connecting to a crypto wallet drainer.

Phishing scammers have cloned the websites of crypto media outlet Blockworks and Ethereum blockchain scanner Etherscan to trick unsuspecting readers into connecting their wallets to a crypto drainer.

A fake Blockworks site displays a fake “BREAKING” news report of a supposed multimillion-dollar “approvals exploit” on the decentralized exchange Uniswap and encourages users to a faked Etherscan website to rescind approvals. 

The fake Uniswap news article was posted on Reddit across several popular crypto-related subreddits by seemingly compromised Reddit accounts.

The fake Etherscan website, which displays a purported token and smart contract approval checker, instead contains a wallet drainer.

Blockchain security firm Beosin reviewed the drainer’s smart contract and told Cointelegraph the attacker hopes to drain wallets with at least 0.1 Ether (ETH), worth $180. However, the drainer is incorrectly set up as “there is no phishing transaction prompted after a wallet is connected.”

An age check of the domains shows the fake Etherscan site, approvalscan.io, was registered on Oct. 25 and the faked Blockworks site, blockworks.media, was registered a day later.

In an Oct. 25 X (Twitter) post, Web3 anti-scam platform Scam Sniffer showed that scammers had deployed a wallet drainer on a website cloning the crypto news outlet Decrypt.

Sam Sniffer told Cointelegraph the faked Blockworks and Decrypt sites are, however, run by different scammers.
