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

Note: This report is updated by a verification record

The package has two files, bun_environment.js and setup_bun.js, that match the bash_persist_persistent YARA rule, indicating access to multiple bash startup files. This could be used for malicious persistence, but it's also possible that the package is legitimately trying to set up a specific environment for Bun. The package.json file also matches the npm_preinstall_command YARA rule, which indicates that the package runs an external command during the preinstall phase. While this is a potential vector for malicious activity, it's not inherently malicious. Given the low confidence and the lack of stronger indicators, I cannot classify this package as malware.
