Simultaneous attacks compromised CoinGecko, Etherscan, Quickswap and other sites

Around 10 PM (UTC) this Friday, it was learned that several platforms related to cryptocurrencies suffered attacks of different types that could put the security of their users’ information at risk, and then perhaps their funds. The situation affected the price and statistics site CoinGecko, the Ethereum block explorer Etherscan and the decentralized exchange (DEX) QuickSwap.

In the case of CoinGecko and Etherscan, Phishing Attack Occurred Via Popup Notification when entering these portals. The message asked to connect the MetaMask wallet to, a type of advertisement that is not normally shown on these sites.

Both platforms reported that the original problem was related to Coinzilla, an advertising service that these pages use. Through a publication On its Twitter account, Coinzilla reported that the problem was caused by malicious code in an advertising campaign that managed to get past the site’s automated security checks.

“It worked for less than an hour before our team stopped it and blocked the account,” added those responsible for this advertising service, who also promised to ensure that the codes in question are removed from any third-party scripts, to help those affected and investigate who perpetrated the attack.

CoinGecko reported through its twitter account that the attack is “disabled now, but there may be some delay due to CDN caching.” “We are monitoring the situation more thoroughly. Stay vigilant and do not plug your MetaMask into CoinGecko,” they added.


As for Etherscan, ad It was similar, in the same social network. “The CoinZilla integration was disabled immediately after receiving the alert. Coinzilla later also informed us that they had fixed this issue on their end. We have been monitoring the situation ever since, we have not seen any new reports,” they wrote from the Ethereum network block explorer account.

Through a Tweetalso held Coinzilla responsible for the issue and requested to “be careful not to sign suspicious requests to your wallet, DEXTools does not automatically ask for any permissions.”

Quickswap, also compromised
