Summary

Hide ▲

MEXC API Automator is a malicious Chrome extension that steals MEXC API keys from authenticated browser sessions and can give attackers control over reachable wallets and balances. It creates new keys with withdrawal permissions, hides that permission in the UI, and sends the Access Key and Secret Key to a hardcoded Telegram bot. Because the keys remain valid until revoked, the abuse can persist even after the extension is removed.
