Description
The npm package 'chai-as-thread' version 7.0.8 is a malicious typosquatting package that executes remote code. Upon requiring the package, it spawns a detached Node.js child process that runs a script which fetches and executes arbitrary JavaScript code from a remote URL. The package name mimics a legitimate package, and its README impersonates another project to lure victims. This behavior enables remote code execution with full require access.
