Which versions of simple-date-formatter-new-7 are malicious?

The following npm versions of simple-date-formatter-new-7 are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate simple-date-formatter-new-7 if I installed it?

Remove simple-date-formatter-new-7 from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed simple-date-formatter-new-7 — how do I know if it already compromised me?

If simple-date-formatter-new-7 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.

Is simple-date-formatter-new-7 part of a known attack campaign?

Yes — simple-date-formatter-new-7 is associated with the IN-MAL-2026-014423 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find simple-date-formatter-new-7 across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for simple-date-formatter-new-7 (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 simple-date-formatter-new-7 across your stack and pipelines.

What this malware does

Package is advertised as a date-formatting utility but its postinstall script probes an internal-range Kubernetes API (10.45.196.138:8080, endpoints /version, /api, /api/v1/namespaces, /api/v1/pods, /api/v1/secrets, /api/v1/nodes plus two adjacent hosts) and POSTs the concatenated responses to an out-of-band collector at safjhdvsfwzhieemkdzbgr54r0yjhrmok.oast.fun/escinfo11. Runs automatically on npm install. The tarball also ships a postinstall.js containing a getSSHKeys() function that enumerates ~/.ssh and POSTs a JSON payload with the directory listing, username, and platform to a hardcoded remote IP 124.221.154.135:443/post over HTTPS. The advertised purpose (formatDate() in index.js) is a thin cover story unrelated to the shipped install-time behavior.
