Confirmed malicious package as part of coordinated supply chain attack targeting npm ecosystem

Note: This report is updated by a verification record

The package exhibits multiple suspicious behaviors. The package.json contains a preinstall script that executes node setup_bun.js, which is flagged as suspicious by the LLM. Both bun_environment.js and setup_bun.js access multiple bash startup files, indicating potential persistence attempts. The combination of these factors suggests malicious intent.
