Description
The npm package 'chai-as-rendered' is a typosquat of 'chai-as-promised' and contains malicious code. It spawns a detached child process that fetches and executes a remote JSON payload, giving the attacker full require access on the host system. The package uses base64 obfuscation to conceal the remote URL and request headers. The package name and keywords impersonate the legitimate 'pino' package to deceive users.
