Malicious VS Code Extensions Masquerading as Solidity Tools Steal Crypto Wallets, API Keys and Credentials
Two malicious Visual Studio Code extensions promoted as Solidity development utilities have been used to steal cryptocurrency wallet data from browsers along with API keys and stored credentials. The extensions, identified as helper-beeps.solidity-pro and web3devtoolsx.solidity-pro, target developers working with smart contracts and Web3 environments where sensitive tokens and sessions are commonly present. Attackers rely on the trusted VS Code marketplace to deliver the payload through a simple installation rather than any complex exploit. Once active, the extensions harvest browser-based crypto wallet information, saved credentials, environment files, SSH keys and API tokens. A single compromised workstation can therefore expose repositories, cloud services and directly drain cryptocurrency funds. Security researchers recommend immediate removal of both extensions, rotation of all accessible secrets and adoption of stricter extension allow-list policies. The incident highlights ongoing supply-chain risks in developer tooling ecosystems.
