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 file contains a preinstall script (setup_bun.js) which is flagged as suspicious by an LLM. The npm_preinstall_command YARA rule also matches this. Furthermore, both setup_bun.js and bun_environment.js match the bash_persist_persistent YARA rule, indicating potential attempts to modify bash startup files for persistence. The combination of these factors suggests malicious intent.
