Description
The weavedb-node-client npm package version 0.45.3 contains a malicious preinstall script that executes a packed native Linux binary. This binary acts as an infostealer targeting developer environments, harvesting credentials for cloud providers, source control, package registries, and cryptocurrency wallets. It also uses kernel-level rootkit techniques to hide its presence and exhibits worm-like behavior by stealing GitHub and npm credentials to propagate further malicious packages. Any system running npm install for this package on Linux is at risk of full compromise.
