Summary
Malicious code in solidity-gas-watcher (npm)
Details

solidity-gas-watcher ships index.js and lib/config.js, byte-identical to the hardhat-roof and chai-foundry payloads: a pino copy whose entry point loads an obfuscated dropper. It is a new name for the hardhat-roof (MAL-2026-17509) and chai-foundry (MAL-2026-13356) campaign; the file hashes below match that record's evidence. The package presents itself as an ordinary utility, so the code runs on import or install without the user knowing.
