Malicious package

alelo-sdknpm

Advisory published Updated

alelo-sdk is a confirmed malicious npm package (MAL-2026-14026) 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.

Malicious code in alelo-sdk (npm)

MAL-2026-14026
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall alelo-sdk

What this malware does

[email protected] ships lifecycle scripts that harvest installer data and POST it to a hardcoded bare-IP endpoint (209.99.185.109) with TLS certificate verification disabled. preinstall.js collects hostname, username, platform, cwd, and the full process.env and sends the JSON to https://209.99.185.109/preinstall. The postinstall path (index.js) additionally reads.env,.npmrc, and parent-directory.env files, executes whoami/id, and POSTs the collected content to https://209.99.185.109/postinstall..npmrc typically contains npm publish tokens and.env files typically contain cloud and API credentials, so any environment where this package is installed (developer workstation or CI) has its secrets extracted. Package metadata (name 'alelo-sdk', version 99.0.0, description 'internal utilities', author 'Alelo Dev Team') is the canonical dependency-confusion shape targeting a private 'alelo' internal scope with an inflated version number.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for alelo-sdk (2 malicious versions).

  2. If you installed it — respond

    alelo-sdk 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.

  3. Did it already run?

    If alelo-sdk 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.

Frequently asked questions

No. alelo-sdk on npm has been identified as a malicious package (versions 99.0.0, 99.0.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks alelo-sdk-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
