Coinmarketcap has been hacked - DO NOT INTERACT
Coinmarketcap has been hacked and is showing a wallet stealer overlay. Do not interact with the site until further clarification.

This attack is probably from a supply chain compromise involving a third party ad network or analytics integration used by CoinMarketCap.
Some malicious actor gained access to inject obfuscated JS through an external script loader, possibly via a compromised ad slot. Not sure yet. The injected code dynamically loads a payload from a really suspicious domain designed to mimic legitimate CDNs. This payload displays a fake CoinMarketCap branded modal prompting users to connect their cryptocurrency wallet, aiming to phish wallet credentials.
CoinMarketCap accounts are likely not compromised. This is a client side injection rather than an internal backdoor.
