Solidity Pro VS Code Extensions Were Stealing Everything
VS Code is a free code editor made by Microsoft, used by millions of developers worldwide. A pair of malicious extensions named "Solidity Pro" lurked inside it, quietly draining credentials, crypto wallets, and API keys from anyone who installed them, according to The Hacker News.
The extensions targeted Ethereum developers by impersonating legitimate coding tools. Early versions quietly contacted external servers to download and run hidden code. Later versions upgraded to full information-stealing malware, capable of harvesting browser profiles, cryptocurrency wallet vaults, SSH private keys, GitHub and GitLab tokens, AWS credentials, OpenAI API keys, and more. Everything collected was sent directly to the attackers via a Telegram bot.
What made this campaign particularly difficult to catch was deliberate patience. The malicious code sat dormant for hours or days after installation. By the time it activated, both the user and automated security scanners had already moved on. The attackers also released clean versions in between to build trust, making detection even harder.
The extensions have been removed from the Open VSX marketplace, but the GitHub repository for one of them remains publicly accessible.
This campaign shares tactics with WhiteCobra, a known threat group previously linked to distributing credential-stealing malware through VS Code extensions.
What you should do: If you have installed any Solidity-related VS Code extensions recently, remove them immediately and audit your installed extension list. Rotate any API keys, tokens, or passwords stored in your development environment. Check your crypto wallet for unauthorised transactions.
