What happened
Blockchain security firm Blockaid detected a front-end attack on Gitcoin’s subdomain files.gitcoin.co. The compromised site contained malicious “Eleven drainer” code designed to steal users’ cryptocurrency wallet assets. Users were advised not to interact with the site while the issue is being investigated and remediated. This is a frontend compromise incident rather than an on-chain smart contract exploit.
