alelo-paymentnpm
Advisory published Updated
alelo-payment is a confirmed malicious npm package (MAL-2026-14025) 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-payment (npm)
What this malware does
On npm install, preinstall.js collects hostname, username, platform, cwd, and the full process.env and POSTs the payload over HTTPS (with TLS verification disabled via rejectUnauthorized:false) to a hardcoded bare IP at 209.99.185.109/preinstall. A postinstall path additionally reads.env,../.env,../../.env,.npmrc, and package.json from the install directory, captures whoami/id output and the full process.env, and POSTs the bundle to 209.99.185.109/postinstall with TLS verification disabled..npmrc contains npm _authToken values and.env typically holds CI/CD secrets and cloud credentials. A bundled PowerShell artifact references publishing under npm account [email protected] and the package name and 99.0.0 version resemble a typosquat / dependency-confusion lure targeting an internal Alelo utility, with no legitimate functionality shipped.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for alelo-payment (2 malicious versions).
If you installed it — respond
alelo-payment 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.
Did it already run?
If alelo-payment 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.

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