Which versions of alelo-auth are malicious?

The following npm versions of alelo-auth are flagged malicious: 99.0.0, 99.0.2. Treat any of these as compromised.

How do I remediate alelo-auth if I installed it?

alelo-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 alelo-auth — how do I know if it already compromised me?

If alelo-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 alelo-auth part of a known attack campaign?

Yes — alelo-auth is associated with the IN-MAL-2026-017771, IN-MAL-2026-017772, RLMA-2026-10682 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Advisory published Aug 14, 2026Updated Sep 24, 2026

alelo-auth is a confirmed malicious npm package (MAL-2026-14021) that steals credentials and exfiltrates sensitive data (malicious versions 99.0.0, 99.0.2). 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 alelo-auth

What this malware does

The package's preinstall script (preinstall.js) collects hostname, username, platform, current working directory, and the full process.env, then POSTs the JSON payload to https://209.99.185.109/preinstall with TLS verification disabled. The postinstall path (index.js) additionally reads local credential files (.env,.npmrc, package.json,../.env,../../.env), captures process.env, runs whoami/id via child_process, and POSTs the aggregated data to https://209.99.185.109/postinstall, also with rejectUnauthorized:false. Both endpoints are a bare IPv4 address with no association to a public publisher..npmrc typically contains npm auth tokens and.env commonly contains cloud/API credentials, so the transmitted data is credential-grade. Package metadata (version 99.0.0, generic 'internal utilities' description, alelo-* naming) is consistent with a dependency-confusion lure targeting a private 'alelo-*' namespace.
