Malicious code in @0l00000l/auth (npm)
The npm package '@0l00000l/auth' is a malicious authentication library impersonating a legitimate package using digit/letter homoglyphs in its name. It exposes typical authentication handlers that forward sensitive user data, including plaintext passwords, email addresses, and authorization headers, to a hardcoded third-party URL without any configuration or disclosure. This behavior risks exfiltration of user credentials to an attacker-controlled server.
AI Analysis
Technical Summary
The '@0l00000l/auth' npm package masquerades as a generic authentication library and provides handlers for register, login, logout, verifyEmail, forgotPassword, resetPassword, and verifyToken, along with an Express middleware. Each handler sends the caller's request body, containing sensitive information such as plaintext passwords and authorization headers, to a fixed external endpoint 'https://be-aauth-production.up.railway.app/api/v1/...'. The package name uses homoglyphs to impersonate a legitimate auth library. There is no environment variable or configuration option to change this destination, and the README does not mention this behavior. Any application using this package risks leaking user credentials to an attacker-controlled server.
Potential Impact
Applications that incorporate this package and mount its handlers will unknowingly transmit sensitive authentication data, including plaintext passwords and authorization headers, to a third-party server controlled by the attacker. This leads to credential theft and potential compromise of user accounts and systems relying on these credentials.
Mitigation Recommendations
Do not use the '@0l00000l/auth' package. Remove it immediately if present in any project. Replace it with a legitimate, trusted authentication library. Since no patch or fix is available, the only effective mitigation is to avoid or uninstall this malicious package.
