Summary
Malicious code in bigbob22-test (npm)
Details

bigbob22-test@1.0.0 has no functional code and an empty README. 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". It was published by the npm account cutekitten05, which used the same script in wallet-adapter-base, axelarjs-sdk, cutekitten-test and sol-wallet-adapter on 2026-11-01.
