Summary
Malicious code in axelarjs-sdk (npm)
Details

axelarjs-sdk@1.0.1 takes the unscoped name of @axelar-network/axelarjs-sdk 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". It was published by the npm account cutekitten05, which published wallet-adapter-base, cutekitten-test, bigbob22-test and sol-wallet-adapter with the same script on 2026-11-01.
