Description
The npm package 'testtestkjkldfnjdfn' contains malicious code that executes during installation via a heavily obfuscated preinstall script. This script uses a large, control-flow-flattened Function constructor to decode and run XOR-encrypted code, enabling arbitrary code execution on the installer's machine without user knowledge. The package masquerades as a utility but primarily serves as a loader for this malicious payload.
