Malicious code in vybscan-testbed-inert-postinstall (npm)
Details
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (f4e6f35e49b7701bb75a88eb63fcf918c389272d5282093c8422d9e1f388dd38) package.json declares a postinstall lifecycle script that runs `id` and reads the process environment, piping the collected host identity and environment variables to a remote endpoint via curl. This fires automatically on `npm install` without user interaction, causing the installer's environment variables (which routinely contain credentials, tokens, and API keys) and user/host identity to be transmitted off-host to an attacker-controlled destination.
