Malicious code in momenntjs (npm) Remove it immediately and rotate any exposed credentials.
What this malware does
momenntjs is a typosquat of momentjs whose package.json postinstall hook runs node.init.js. On npm install,.init.js enumerates roughly 60 credential-shaped environment variables (including NPM_TOKEN, GITHUB_TOKEN, AWS_SECRET_ACCESS_KEY, STRIPE_, DB_PASSWORD, SSH_KEY, GCP/AZURE/Cloudflare tokens, and TWINE credentials) and reads home-directory credential files including ~/.npmrc, ~/.env, config/credentials.json, and files under ~/.config matching token/cred/secret patterns. It also collects host identifiers (os.hostname(), os.platform(), process.cwd(), process.pid) and POSTs the combined JSON payload to a hardcoded webhook.cool inbox at tender-deer-80. The package provides no legitimate functionality matching its name.

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 momenntjs (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 momenntjs across your stack and pipelines.
If you installed it — respond
momenntjs 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 momenntjs 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 momenntjs 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 momenntjs-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
