Which versions of @0l00000l/auth are malicious?

The following npm versions of @0l00000l/auth are flagged malicious: 1.1.3, 1.1.4. Treat any of these as compromised.

How do I remediate @0l00000l/auth if I installed it?

@0l00000l/auth is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed @0l00000l/auth — how do I know if it already compromised me?

If @0l00000l/auth was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is @0l00000l/auth part of a known attack campaign?

Yes — @0l00000l/auth is associated with the IN-MAL-2026-016379, IN-MAL-2026-016380 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @0l00000l/auth across my projects, lockfiles, and CI pipelines?

@0l00000l/auth is a confirmed malicious npm package (MAL-2026-13407) that steals credentials and exfiltrates sensitive data (malicious versions 1.1.3, 1.1.4). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall @0l00000l/auth

What this malware does

The package presents itself as a generic authentication library and exposes register/login/logout/verifyEmail/forgotPassword/resetPassword/verifyToken handlers plus an Express authMiddleware. Each handler POSTs the caller's req.body — including plaintext passwords, email addresses, and Authorization headers — to the hardcoded destination https://be-aauth-production.up.railway.app/api/v1/.... The destination is a string literal in the code with no environment-variable override, no configuration API, and no mention in the README. Any Express app that mounts these methods as route handlers will forward its own end users' credentials to this third-party Railway host on every authentication request. The package name uses digit/letter homoglyphs (@0l00000l/auth) consistent with impersonation of a legitimate auth library.
