Malicious code in @sudoughnym/enviro-demo (npm)
Details
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (02c1c204d0f458d13d7140f4b7a007d551095665a418e9146037be9a5b2b7957) @sudoughnym/enviro-demo@99.99.99 ships preinstall.js and postinstall.js lifecycle scripts that run automatically on `npm install`. Both scripts collect host identifiers and environment metadata — os.hostname(), process.cwd(), pid, node version, platform, process.env.USER, the first ten environment variable names, and the total env count — and POST them as JSON to https://webhook.site/f83b073c-a04a-4ac5-8930-507051bd22f7, a third-party webhook capture service not associated with the package's stated publisher. The package version (99.99.99) and its own description identify it as a dependency-confusion proof-of-concept targeting an internal `enviro` package name; the inflated semver is intended to outrank private-registry versions so internal build systems resolve to this public package. Installer harm: any build or developer machine that resolves to this version leaks host identity and environment-variable layout (which can include secret-bearing variable names) to an attacker-controlled endpoint on every install.
