zomato-confignpm
Advisory published Updated
zomato-config is a confirmed malicious npm package (MAL-2026-6251) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in zomato-config (npm)
What this malware does
Dependency-confusion package targeting an internal Zomato namespace. The package ships only a stub index.js (module.exports = { name: 'zomato-config', version: '1.0.0' }) with no real functionality. Its package.json preinstall lifecycle hook runs curl to POST hostname, whoami, pwd, and the full process environment (base64-encoded via env | base64 -w0) to http://d8s0b82plbq3u5sb2vo0sb3a9obr4yjt7.oast.site/install/.... This fires automatically on npm install and leaks any environment-variable secrets present at install time (CI tokens, cloud credentials, npm/GitHub tokens) to an attacker-controlled out-of-band interaction host. The shape (empty payload + recon beacon to oast.site + internal-sounding name) matches a dependency-confusion reconnaissance / exfiltration package.
The OpenSSF Package Analysis project identified 'zomato-config' @ 1.0.0 (npm) as malicious.
It is considered malicious because:
-
The package communicates with a domain associated with malicious activity.
-
The package executes one or more commands associated with malicious behavior.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for zomato-config (version 1.0.0).
If you installed it — respond
zomato-config 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 zomato-config 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 zomato-config-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
