zomato-servernpm
Malicious code in zomato-server (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
The package's package.json declares a preinstall lifecycle hook that runs curl to POST the installer's hostname, whoami, current working directory, and a base64-encoded dump of the full process environment to http://d8s0b82plbq3u5sb2vo0sb3a9obr4yjt7.oast.site over plain HTTP. The destination is an Interactsh-style out-of-band collection subdomain unrelated to any legitimate Zomato infrastructure. This fires automatically on npm install without user consent, leaking any credentials, tokens, or secrets present in environment variables (CI tokens, npm auth, AWS keys, etc.). The package itself ships only a 62-byte stub index.js exporting { name, version } and impersonates the Zomato brand (description 'Zomato server-side utilities', repo pointing at github.com/zomato/zomato-server), consistent with a dependency-confusion lure targeting Zomato internal builds.
The OpenSSF Package Analysis project identified 'zomato-server' @ 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
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for zomato-server (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging zomato-server across your stack and pipelines.
If you installed it — respond
zomato-server 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-server was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks zomato-server before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

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